Enumerator

kOnlyPrepStep

Used to request that the class specific implementation of TObject::Write just prepare the objects to be ready to be written but do not actually write them into the TBuffer. This is just for example by TBufferMerger to request that the TTree inside the file calls TTree::FlushBaskets (outside of the merging lock) and TBufferMerger will later ask for the write (inside the merging lock). To take advantage of this feature the class needs to overload TObject::Write and use this enum value accordingly. (See TTree::Write and TObject::Write) Do not use, this feature will be migrate to the Merge function (See TClass and TTree::Merge)

AbstractMethod()

void TObject::AbstractMethod ( const char * method ) const

inherited

Call this function within a function that you don't want to define as purely virtual, in order not to force all users deriving from that class to implement that maybe (on their side) unused function; but at the same time, emit a run-time warning if they try to call it, telling that it is not implemented in the derived class: action must thus be taken on the user side to override it.

In other word, this method acts as a "runtime purely virtual" warning instead of a "compiler purely virtual" error.

Warning

This interface is a legacy function that is no longer recommended to be used by new development code.

Note

The name "AbstractMethod" does not imply that it's an abstract method in the strict C++ sense.

Definition at line 1149 of file TObject.cxx.

AddToTObjectTable()

void TObject::AddToTObjectTable ( TObject * op )

staticprivateinherited

Private helper function which will dispatch to TObjectTable::AddObj.

Included here to avoid circular dependency between header files.

AppendPad()

void TObject::AppendPad ( Option_t * option = "" )

virtualinherited

Append graphics object to current pad.

In case no current pad is set yet, create a default canvas with the name "c1".

CheckedHash()

ULong_t TObject::CheckedHash ( )

inlineinherited

Check and record whether this class has a consistent Hash/RecursiveRemove setup (*) and then return the regular Hash value for this object.

The intent is for this routine to be called instead of directly calling the function Hash during "insert" operations. See TObject::HasInconsistenTObjectHash();

(*) The setup is consistent when all classes in the class hierarchy that overload TObject::Hash do call ROOT::CallRecursiveRemoveIfNeeded in their destructor. i.e. it is safe to call the Hash virtual function during the RecursiveRemove operation.

Clone()

TObject * TObject::Clone ( const char * newname = "" ) const

virtualinherited

Make a clone of an object using the Streamer facility.

If the object derives from TNamed, this function is called by TNamed::Clone. TNamed::Clone uses the optional argument to set a new name to the newly created object.

If the object class has a DirectoryAutoAdd function, it will be called at the end of the function with the parameter gDirectory. This usually means that the object will be appended to the current ROOT directory.

GetErrorCode()

Int_t TSQLStatement::GetErrorCode ( ) const

virtualinherited

Abstract base class defining SQL statements, which can be submitted in bulk to DB server.

This is alternative to TSQLServer::Query() method, which allows only pure text queries and pure text result in TSQLResult classes. TSQLStatement is designed to support following features:

• usage of basic data types (like int or double) as parameters in SQL statements
• bulk operation when inserting/updating/selecting data in database
• uasge of basic data types when accessing result set of executed query

1. Creation of statement

To create an instance of the TSQLStatement class, the TSQLServer::Statement() method should be used. Depending on the driver used for an ODBC connection, the appropriate object instance will be created. For the moment there are six different implementations of the TSQLStatement class: for MySQL, Oracle, PostgreSQL, SQLite3 and ODBC. Hopefully, support of ODBC will allow usage of statements for most existing RDBMS.

// first, connect to the database TSQLServer* serv = TSQLServer::Connect("mysql://hostname.domain:3306/test", "user", "pass"); // check if connection is ok if ((serv!=0) && serv->IsConnected()) { // create instance of sql-statement TSQLStatement* stmt = serv->Statement("CREATE TABLE TESTTABLE (ID1 INT, ID2 INT, FFIELD VARCHAR(255), FVALUE VARCHAR(255))"; // process statement stmt->Process(); // destroy object delete stmt; } delete serv;

2. Insert data to data base

There is a special syntax of SQL queries which allows to use values provided as parameters. For instance, to insert one row into the TESTTABLE created with the previous example, one can simply execute a query like:

serv->Query("INSERT INTO TESTTABLE VALUES (1, 2, \"name1\", \"value1\"");

However, when many (100-1000) rows should be inserted, each call of TSQLServer::Query() method will cause communication loop with database server, and the statement has to be evaluated each time instead of using a prepared statement. As a result, insertion of data takes too much time.

TSQLStatement provides a mechanism to insert many rows at once. First of all, an appropriate statement should be created:

TSQLStatement* stmt = serv->Statement("INSERT INTO TESTTABLE (ID1, ID2, FFIELD, FVALUE) VALUES (?, ?, ?, ?)", 100);

Here question marks "?" indicate where statement parameters can be inserted. To specify values of parameters, SetInt(), SetDouble(), SetString() and other methods of the TSQLStatement class should be used. Before parameters values can be specified, the NextIteration() method of statement class should be called. For each new row, NextIteration() has to be called first, then parameters values are specified. There is one limitation for most type-aware DBMS - once a parameter is set as integer via SetInt(), all other rows should be specified as integer. At the end, TSQLStatement::Process() should be called. Here a small example:

// first, create statement TSQLStatement* stmt = serv->Statement("INSERT INTO TESTTABLE (ID1, ID2, FFIELD, FVALUE) VALUES (?, ?, ?, ?)", 100);

for (int n=0;n<357;n++) if (stmt->NextIteration()) { stmt->SetInt(0, 123); stmt->SetUInt(1, n+10); stmt->SetString(2, Form("name %d",n), 200); stmt->SetString(3, Form("value %d", n+10), 200); }

stmt->Process(); delete stmt;

The second argument in the TSQLServer::Statement() method specifies the depth of of buffers which are used to keep parameter values (100 in the example). It is not a limitation of the number of rows which can be inserted with the statement. When buffers are filled, they will be submitted to database and can be reused again. This happens transparent to the user in the NextIteration() method.

Oracle and some ODBC drivers support buffering of parameter values and, as a result, bulk insert (update) operation. MySQL (native driver and MyODBC 3) does not support such a mode of operation, therefore adding new rows will result in communication loop to database.

Local databases (SQLite3) do not use any buffering at all in the TSQLStatement implementation (but inside the library). They still profit from the usage of prepared statements. When inserting many rows into a SQLite3 database, consider using a transaction via the methods StartTransaction() and Commit() of the TSQLServer, as autocommit is active by default and causes a sync to disk after each single insert.

One should also mention differences between Oracle and ODBC SQL syntax for parameters. ODBC (and MySQL) use question marks to specify the position where parameters should be inserted (as shown in the example). Oracle uses :1, :2 and so on as marks to specify the position of parameter 0, 1, and so on. Therefore, similar to the example, a query will look like:

TSQLStatement* stmt = serv->Statement("INSERT INTO TESTTABLE (ID1, ID2, FFIELD, FVALUE) VALUES (:1, :2, :3, :4)", 100);

SQLite3 supports both these syntaxes and some more.

There is a possibility to set a parameter value to NULL with the SetNull() method. If this method is to be called for the first iteration, one should first call another Set... method to identify the actual type which will be used for the parameter later.

3. Getting data from database

To request data from a database, the SELECT statement should be used. After a SELECT statement is created, it must be processed with the TSQLStatement::Process() method and the result of statement should be stored in internal buffers with the method TSQLStatement::StoreResult(). Information about selected fields (columns) can be obtained with GetNumFields() and GetFieldName() methods. To receive data for the next result row, NextResultRow() method should be called. Value from each column can be retrieved with the GetInt(), GetDouble(), GetString() and other methods.

There are no strict limitations on which method should be used to get column values. GetString() can be used as a generic method, which should always return correct result, but also conversions between most basic data types are supported. For instance, if a column contains integer values, GetInt(), GetLong64(), GetDouble() and GetString() methods can be used. If column has floating point format, GetDouble() and GetString() methods can be used without loss of precision while GetInt() or GetLong64() will return only the integer part of the value. One also can test whether a value is NULL with the IsNull() method.

The buffer length specified for a statement in the TSQLServer::Statement() call will also be used to allocate buffers for column values. Usage of these buffers is transparent for users and does not limit the number of rows which can be accessed with one statement. Again, local databases do not work with buffers inside TSQLStatement at all and ignore this value. Example of select query:

stmt = serv->Statement("SELECT * FROM TESTTABLE", 100); // process statement if (stmt->Process()) { // store result of statement in buffer stmt->StoreResult();

// display info about selected field std::cout << "NumFields = " << stmt->GetNumFields() << std::endl; for (int n=0;n<stmt->GetNumFields();n++) std::cout << "Field " << n << " = " << stmt->GetFieldName(n) << std::endl;

// extract rows one after another while (stmt->NextResultRow()) { Double_t id1 = stmt->GetDouble(0); UInt_t id2 = stmt->GetUInt(1); const char* name1 = stmt->GetString(2); const char* name2 = stmt->GetString(3); std::cout << id1 << " - " << id2 << " " << name1 << " " << name2 << std::endl; } }

4. Working with date/time parameters

The current implementation supports date, time, date&time and timestamp data (all time intervals are not supported yet). To set or get date/time values, the following methods should be used: SetTime()/GetTime() - only time (hour:min:sec), SetDate()/GetDate() - only date (year-month-day), SetDatime()/GetDatime() - date and time SetTimestamp()/GetTimestamp() - timestamp with seconds fraction For some of these methods TDatime type can be used as parameter / return value. Be aware that TDatime supports only dates after 1995-01-01. There are also methods to get year, month, day, hour, minutes and seconds separately.

Note that different SQL databases treat date/time types differently. For instance, MySQL has all correspondent types (TIME, DATE, DATETIME and TIMESTAMP), Oracle native driver supports only DATE (which is actually date and time) and TIMESTAMP ODBC interface provides access for time, date and timestamps, for PostgreSQL, TIMESTAMP is available and can be retrieved via all methods, the implementation for SQLite interprets the column content as a timestamp with second fraction. Due to these differences, one should use correct methods to access such data. For instance, in MySQL SQL type 'DATE' is only date (one should use GetDate() to access such data), while in Oracle it is date and time. Therefore, to get complete data from a 'DATE' column in Oracle, one should use the GetDatime() method.

The only difference between timestamp and date/time is that timestamp has a fractional seconds part. Be aware that the fractional part has different meanings (actual value) in different SQL plugins. For PostgreSQL, it is given back as microseconds, while for SQLite3, milliseconds correspond to the fraction (similar to the DATETIME-functions implemented in the SQLite3 language).

5. Binary data

Most modern data bases support just binary data, which is typically has SQL type name 'BLOB'. To access data in such columns, GetBinary()/SetBinary() methods should be used. The current implementation implies that the complete content of the column must be retrieved at once. Therefore, very big data of gigabytes size may cause a problem.

In addition, for PostgresSQL, the methods GetLargeObject()/SetLargeObject() are implemented with similar syntax. They retrieve a large object for the OID given in the column of the statement. For non-PostgreSQL databases, calling GetLargeObject()/SetLargeObject() is redirected to GetBinary()/SetBinary().

Since ROOT 6.36, the GetLargeObject/GetBinary(Int_t col, void* &mem, Long_t& size) API is defined strictly to return new memory mem that must be released with delete [] (unsigned char *) mem by the caller. Older uses of this API (such as those of oracle, mysql, odbc) that relied on internal buffer management (owning pointers) were removed in ROOT 6.38. returns error code of last operation if res==0, no error Each specific implementation of TSQLStatement provides its own error coding

Hash()

ULong_t TObject::Hash ( ) const

virtualinherited

Return hash value for this object.

Note: If this routine is overloaded in a derived class, this derived class should also add

ROOT::CallRecursiveRemoveIfNeeded(*this)

Otherwise, when RecursiveRemove is called (by ~TObject or example) for this type of object, the transversal of THashList and THashTable containers will will have to be done without call Hash (and hence be linear rather than logarithmic complexity). You will also see warnings like

Error in <ROOT::Internal::TCheckHashRecursiveRemoveConsistency::CheckRecursiveRemove>: The class SomeName overrides
TObject::Hash but does not call TROOT::RecursiveRemove in its destructor.

HasInconsistentHash()

Bool_t TObject::HasInconsistentHash ( ) const

inlineinherited

Return true is the type of this object is known to have an inconsistent setup for Hash and RecursiveRemove (i.e.

missing call to RecursiveRemove in destructor).

Note: Since the consistency is only tested for during inserts, this routine will return true for object that have never been inserted whether or not they have a consistent setup. This has no negative side-effect as searching for the object with the right or wrong Hash will always yield a not-found answer (Since anyway no hash can be guaranteed unique, there is always a check)

SaveAs()

void TObject::SaveAs ( const char * filename = "", Option_t * option = "" ) const

virtualinherited

Save this object in the file specified by filename.

• if "filename" contains ".root" the object is saved in filename as root binary file.
• if "filename" contains ".xml" the object is saved in filename as a xml ascii file.
• if "filename" contains ".cc" the object is saved in filename as C code independent from ROOT. The code is generated via SavePrimitive(). Specific code should be implemented in each object to handle this option. Like in TF1::SavePrimitive().

• otherwise the object is written to filename as a CINT/C++ script. The C++ code to rebuild this object is generated via SavePrimitive(). The "option" parameter is passed to SavePrimitive. By default it is an empty string. It can be used to specify the Draw option in the code generated by SavePrimitive.

Definition at line 989 of file TObject.cxx.

Write() [2/2]

Int_t TObject::Write ( const char * name = nullptr, Int_t option = 0, Int_t bufsize = 0 ) const

virtualinherited

Write this object to the current directory.

The data structure corresponding to this object is serialized. The corresponding buffer is written to the current directory with an associated key with name "name".

Writing an object to a file involves the following steps:

• Creation of a support TKey object in the current directory. The TKey object creates a TBuffer object.
• The TBuffer object is filled via the class::Streamer function.
• If the file is compressed (default) a second buffer is created to hold the compressed buffer.
• Reservation of the corresponding space in the file by looking in the TFree list of free blocks of the file.
• The buffer is written to the file.

Bufsize can be given to force a given buffer size to write this object. By default, the buffersize will be taken from the average buffer size of all objects written to the current file so far.

If a name is specified, it will be the name of the key. If name is not given, the name of the key will be the name as returned by GetName().

The option can be a combination of: kSingleKey, kOverwrite or kWriteDelete Using the kOverwrite option a previous key with the same name is overwritten. The previous key is deleted before writing the new object. Using the kWriteDelete option a previous key with the same name is deleted only after the new object has been written. This option is safer than kOverwrite but it is slower. NOTE: Neither kOverwrite nor kWriteDelete reduces the size of a TFile– the space is simply freed up to be overwritten; in the case of a TTree, it is more complicated. If one opens a TTree, appends some entries, then writes it out, the behaviour is effectively the same. If, however, one creates a new TTree and writes it out in this way, only the metadata is replaced, effectively making the old data invisible without deleting it. TTree::Delete() can be used to mark all disk space occupied by a TTree as free before overwriting its metadata this way. The kSingleKey option is only used by TCollection::Write() to write a container with a single key instead of each object in the container with its own key.

An object is read from the file into memory via TKey::Read() or via TObject::Read().

The function returns the total number of bytes written to the file. It returns 0 if the object cannot be written.

Reimplemented in TBuffer, TCollection, TDirectory, TDirectoryFile, TFile, TMap, TParallelMergingFile, TSQLFile, TTree, and TXMLFile.
