ROOT top level object description.
The TROOT object is the entry point to the ROOT system. The single instance of TROOT is accessible via the global gROOT. Using the gROOT pointer one has access to basically every object created in a ROOT based program. The TROOT object is essentially a container of several lists pointing to the main ROOT objects.
The following lists are accessible from gROOT object:
The TROOT class provides also many useful services:
The ROOT object must be created as a static object. An example of a main program creating an interactive version is shown below:

Initialize the ROOT system.
The creation of the TROOT object initializes the ROOT system. It must be the first ROOT related action that is performed by a program. The TROOT object must be created on the stack (can not be called via new since "operator new" is protected). The TROOT object is either created as a global object (outside the main() program), or it is one of the first objects created in main(). Make sure that the TROOT object stays in scope for as long as ROOT related actions are performed. TROOT is a so called singleton so only one instance of it can be created. The single TROOT object can always be accessed via the global pointer gROOT. The name and title arguments can be used to identify the running application. The initfunc argument can contain an array of function pointers (last element must be 0). These functions are executed at the end of the constructor. This way one can easily extend the ROOT system without adding permanent dependencies (e.g. the graphics system is initialized via such a function).

Reimplemented from TDirectory.
| Bool_t TROOT::IsRootFile | ( | const char * | filename | ) | const |
Check if class "classname" is known to the interpreter (in fact, this check is not needed anymore, so classname is ignored).
If not it will load library "libname". If the library couldn't be found with original libname and if the name was not prefixed with lib, try to prefix with "lib" and search again. If DynamicPathName still couldn't find the library, return -1. If check is true it will only check if libname exists and is readable. Returns 0 on successful loading, -1 in case libname does not exist or in case of error and -2 in case of version mismatch.
Helper function used by TClass::GetClass().
This function attempts to load the dictionary for 'classname' either from the TClassTable or from the list of generator. If silent is 'true', do not warn about missing dictionary for the class. (typically used for class that are used only for transient members)
The 'requestedname' is expected to be already normalized.
Load a macro in the interpreter's memory.
Equivalent to the command line command ".L filename". If the filename has "+" or "++" appended the macro will be compiled by ACLiC. The filename must have the format: [path/]macro.C[+|++[g|O]]. The possible error codes are defined by TInterpreter::EErrorCode. If check is true it will only check if filename exists and is readable. Returns 0 on successful loading and -1 in case filename does not exist or in case of error.

Execute a macro in the interpreter.
Equivalent to the command line command ".x filename". If the filename has "+" or "++" appended the macro will be compiled by ACLiC. The filename must have the format: [path/]macro.C[+|++[g|O]][(args)]. The possible error codes are defined by TInterpreter::EErrorCode. If padUpdate is true (default) update the current pad. Returns the macro return value.

Process interpreter command via TApplication::ProcessLine().
On Win32 the line will be processed asynchronously by sending it to the CINT interpreter thread. For explicit synchronous processing use ProcessLineSync(). On non-Win32 platforms there is no difference between ProcessLine() and ProcessLineSync(). The possible error codes are defined by TInterpreter::EErrorCode. In particular, error will equal to TInterpreter::kProcessing until the CINT interpreted thread has finished executing the line. Returns the result of the command, cast to a Longptr_t.
Process interpreter command directly via CINT interpreter.
Only executable statements are allowed (no variable declarations), In all other cases use TROOT::ProcessLine(). The possible error codes are defined by TInterpreter::EErrorCode.
Process interpreter command via TApplication::ProcessLine().
On Win32 the line will be processed synchronously (i.e. it will only return when the CINT interpreter thread has finished executing the line). On non-Win32 platforms there is no difference between ProcessLine() and ProcessLineSync(). The possible error codes are defined by TInterpreter::EErrorCode. Returns the result of the command, cast to a Longptr_t.

Delete all global interpreter objects created since the last call to Reset.
If option="a" is set reset to startup context (i.e. unload also all loaded files, classes, structs, typedefs, etc.).
This function is typically used at the beginning (or end) of an unnamed macro to clean the environment.
IMPORTANT WARNING: Do not use this call from within any function (neither compiled nor interpreted. This should only be used from a unnamed macro (which starts with a { (curly braces) ). For example, using TROOT::Reset from within an interpreted function will lead to the unloading of the dictionary and source file, including the one defining the function being executed.
