Constructor & Destructor Documentation

◆ TMessage() [1/3]

TMessage::TMessage ( const TMessage & )

private

◆ TMessage() [2/3]

TMessage::TMessage	(	void *	buf,
		Int_t	bufsize
	)

protected

Create a TMessage object for reading objects.

The objects will be read from buf. Use the What() method to get the message type.

Definition at line 71 of file TMessage.cxx.

◆ TMessage() [3/3]

TMessage::TMessage	(	UInt_t	what = `kMESS_ANY`,
		Int_t	bufsiz = `TBuffer::kInitialSize`
	)

Create a TMessage object for storing objects.

The "what" integer describes the type of message. Predifined ROOT system message types can be found in MessageTypes.h. Make sure your own message types are unique from the ROOT defined message types (i.e. 0 - 10000 are reserved by ROOT). In case you OR "what" with kMESS_ACK, the message will wait for an acknowledgement from the remote side. This makes the sending process synchronous. In case you OR "what" with kMESS_ZIP, the message will be compressed in TSocket using the zip algorithm (only if message is > 256 bytes).

Definition at line 46 of file TMessage.cxx.

◆ ~TMessage()

TMessage::~TMessage ( )

virtual

Clean up compression buffer.

Definition at line 106 of file TMessage.cxx.

Member Function Documentation

◆ CompBuffer()

char * TMessage::CompBuffer ( ) const

inline

Definition at line 89 of file TMessage.h.

◆ CompLength()

Int_t TMessage::CompLength ( ) const

inline

Definition at line 90 of file TMessage.h.

◆ Compress()

Int_t TMessage::Compress ( )

Compress the message.

The message will only be compressed if the compression level > 0 and the if the message is > 256 bytes. Returns -1 in case of error (when compression fails or when the message increases in size in some pathological cases), otherwise returns 0.

Definition at line 302 of file TMessage.cxx.

◆ EnableSchemaEvolution()

void TMessage::EnableSchemaEvolution ( Bool_t enable = kTRUE )

inline

Definition at line 78 of file TMessage.h.

◆ EnableSchemaEvolutionForAll()

void TMessage::EnableSchemaEvolutionForAll ( Bool_t enable = kTRUE )

static

Static function enabling or disabling the automatic schema evolution.

By default schema evolution support is off.

Definition at line 116 of file TMessage.cxx.

◆ ForceWriteInfo()

void TMessage::ForceWriteInfo	(	TVirtualStreamerInfo *	info,
		Bool_t	force
	)

virtual

Force writing the TStreamerInfo to the message.

Reimplemented from TBufferIO.

Definition at line 132 of file TMessage.cxx.

◆ Forward()

void TMessage::Forward ( )

Change a buffer that was received into one that can be send, i.e.

forward a just received message.

Definition at line 144 of file TMessage.cxx.

◆ GetClass()

TClass * TMessage::GetClass ( ) const

inline

Definition at line 71 of file TMessage.h.

◆ GetCompressionAlgorithm()

Int_t TMessage::GetCompressionAlgorithm ( ) const

inline

Definition at line 100 of file TMessage.h.

◆ GetCompressionLevel()

Int_t TMessage::GetCompressionLevel ( ) const

inline

Definition at line 106 of file TMessage.h.

◆ GetCompressionSettings()

Int_t TMessage::GetCompressionSettings ( ) const

inline

Definition at line 112 of file TMessage.h.

◆ GetStreamerInfos()

TList * TMessage::GetStreamerInfos ( ) const

inline

Definition at line 80 of file TMessage.h.

◆ operator=()

void TMessage::operator= ( const TMessage & )

private

◆ Reset() [1/2]

void TMessage::Reset ( void )

virtual

Reset the message buffer so we can use (i.e. fill) it again.

Reimplemented from TBufferIO.

Definition at line 178 of file TMessage.cxx.

◆ Reset() [2/2]

void TMessage::Reset ( UInt_t what )

inline

Definition at line 74 of file TMessage.h.

◆ SetCompressionAlgorithm()

void TMessage::SetCompressionAlgorithm ( Int_t algorithm = ROOT::RCompressionSetting::EAlgorithm::kUseGlobal )

Definition at line 240 of file TMessage.cxx.

◆ SetCompressionLevel()

void TMessage::SetCompressionLevel ( Int_t level = ROOT::RCompressionSetting::ELevel::kUseMin )

Definition at line 261 of file TMessage.cxx.

◆ SetCompressionSettings()

void TMessage::SetCompressionSettings ( Int_t settings = ROOT::RCompressionSetting::EDefaults::kUseGeneralPurpose )

Definition at line 284 of file TMessage.cxx.

◆ SetLength()

void TMessage::SetLength ( ) const

protected

Set the message length at the beginning of the message buffer.

This method is only called by TSocket::Send().

Definition at line 201 of file TMessage.cxx.

◆ SetWhat()

void TMessage::SetWhat ( UInt_t what )

Using this method one can change the message type a-posteriory.

In case you OR "what" with kMESS_ACK, the message will wait for an acknowledgement from the remote side. This makes the sending process synchronous.

Definition at line 221 of file TMessage.cxx.

◆ TagStreamerInfo()

void TMessage::TagStreamerInfo ( TVirtualStreamerInfo * info )

virtual

Remember that the StreamerInfo is being used in writing.

When support for schema evolution is enabled the list of TStreamerInfo used to stream this object is kept in fInfos. This information is used by TSocket::Send that sends this list through the socket. This list is in turn used by TSocket::Recv to store the TStreamerInfo objects in the relevant TClass in case the TClass does not know yet about a particular class version. This feature is implemented to support clients and servers with either different ROOT versions or different user classes versions.

Reimplemented from TBufferIO.

Definition at line 167 of file TMessage.cxx.

◆ TestBitNumber()

Bool_t TMessage::TestBitNumber ( UInt_t bitnumber ) const

inlineprivate

Definition at line 59 of file TMessage.h.

◆ Uncompress()

Int_t TMessage::Uncompress ( )

Uncompress the message.

The message will only be uncompressed when kMESS_ZIP is set. Returns -1 in case of error, 0 otherwise.

Definition at line 387 of file TMessage.cxx.

◆ UsesSchemaEvolution()

Bool_t TMessage::UsesSchemaEvolution ( ) const

inline

Definition at line 79 of file TMessage.h.

◆ UsesSchemaEvolutionForAll()

Bool_t TMessage::UsesSchemaEvolutionForAll ( )

static

Static function returning status of global schema evolution.

Definition at line 124 of file TMessage.cxx.

◆ What()

UInt_t TMessage::What ( ) const

inline

Definition at line 75 of file TMessage.h.

◆ WriteProcessID()

UShort_t TMessage::WriteProcessID ( TProcessID * pid )

virtual

Check if the ProcessID pid is already in the message.

If not, then:

mark bit 0 of fBitsPIDs to indicate that a ProcessID has been found
mark bit uid+1 where uid id the uid of the ProcessID

Reimplemented from TBufferIO.
