virtual

Send a character string buffer.

Use kind to set the TMessage "what" field. Returns the number of bytes in the string str that were sent and -1 in case of error. In case the kind has been or'ed with kMESS_ACK, the call will only return after having received an acknowledgement, making the sending process synchronous.

◆ Send() [2/4]

Int_t TUDPSocket::Send ( const TMessage & mess )

virtual

Send a TMessage object.

Returns the number of bytes in the TMessage that were sent and -1 in case of error. In case the TMessage::What has been or'ed with kMESS_ACK, the call will only return after having received an acknowledgement, making the sending process synchronous. Returns -4 in case of kNoBlock and errno == EWOULDBLOCK. Returns -5 if pipe broken or reset by peer (EPIPE || ECONNRESET). support for streaming TStreamerInfo added by Rene Brun May 2008 support for streaming TProcessID added by Rene Brun June 2008

◆ Send() [3/4]

Int_t TUDPSocket::Send ( Int_t kind )

virtual

Send a single message opcode.

Use kind (opcode) to set the TMessage "what" field. Returns the number of bytes that were sent (always sizeof(Int_t)) and -1 in case of error. In case the kind has been or'ed with kMESS_ACK, the call will only return after having received an acknowledgement, making the sending process synchronous.

Definition at line 427 of file TUDPSocket.cxx.

◆ Send() [4/4]

Int_t TUDPSocket::Send	(	Int_t	status,
		Int_t	kind
	)

virtual

Send a status and a single message opcode.

Use kind (opcode) to set the TMessage "what" field. Returns the number of bytes that were sent (always 2*sizeof(Int_t)) and -1 in case of error. In case the kind has been or'ed with kMESS_ACK, the call will only return after having received an acknowledgement, making the sending process synchronous.

Definition at line 445 of file TUDPSocket.cxx.

◆ SendObject()

Int_t TUDPSocket::SendObject	(	const TObject *	obj,
		Int_t	kind = `kMESS_OBJECT`
	)

virtual

Send an object.

Returns the number of bytes sent and -1 in case of error. In case the "kind" has been or'ed with kMESS_ACK, the call will only return after having received an acknowledgement, making the sending synchronous.

Definition at line 566 of file TUDPSocket.cxx.

◆ SendProcessIDs()

void TUDPSocket::SendProcessIDs ( const TMessage & mess )

protected

Check if TProcessIDs must be sent.

The list of TProcessIDs in the object in the message is found by looking in the TMessage bits. We send only the TProcessIDs not yet send on this socket.

Definition at line 651 of file TUDPSocket.cxx.

◆ SendRaw()

Int_t TUDPSocket::SendRaw	(	const void *	buffer,
		Int_t	length,
		ESendRecvOptions	opt = `kDefault`
	)

virtual

Send a raw buffer of specified length.

Using option kOob one can send OOB data. Returns the number of bytes sent or -1 in case of error. Returns -4 in case of kNoBlock and errno == EWOULDBLOCK. Returns -5 if pipe broken or reset by peer (EPIPE || ECONNRESET).

Definition at line 586 of file TUDPSocket.cxx.

◆ SendStreamerInfos()

void TUDPSocket::SendStreamerInfos ( const TMessage & mess )

protected

Check if TStreamerInfo must be sent.

The list of TStreamerInfo of classes in the object in the message is in the fInfos list of the message. We send only the TStreamerInfos not yet sent on this socket.

◆ SetCompressionAlgorithm()

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

See comments for function SetCompressionSettings.

Definition at line 1016 of file TUDPSocket.cxx.

◆ SetCompressionLevel()

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

See comments for function SetCompressionSettings.

Definition at line 1031 of file TUDPSocket.cxx.

◆ SetCompressionSettings()

void TUDPSocket::SetCompressionSettings ( Int_t settings = ROOT::RCompressionSetting::EDefaults::kUseCompiledDefault )

Used to specify the compression level and algorithm: settings = 100 * algorithm + level.

level = 0, objects written to this file will not be compressed. level = 1, minimal compression level but fast. .... level = 9, maximal compression level but slower and might use more memory. (For the currently supported algorithms, the maximum level is 9) If compress is negative it indicates the compression level is not set yet.

The enumeration ROOT::RCompressionSetting::EAlgorithm associates each algorithm with a number. There is a utility function to help to set the value of the argument. For example, ROOT::CompressionSettings(ROOT::kLZMA, 1) will build an integer which will set the compression to use the LZMA algorithm and compression level 1. These are defined in the header file Compression.h.

Note that the compression settings may be changed at any time. The new compression settings will only apply to branches created or attached after the setting is changed and other objects written after the setting is changed.
