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::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).

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.

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

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.
