Detailed Description

TCPSession2

TCPSession defines the nature of the interaction with the client and stores persistent data for a defined session. TCPSession objects are not sockets but instead provide a communications control mechanism. Protocol conversations are provided through extensions from this object.

TCPSession2 is designed to be 'connected' instead of being served by a server.

Member Function Documentation

onBlockReceived()

void core::TCPSession2::onBlockReceived ( coreutils::ZString &  block )

protectedvirtual

Override the onBlockReceived method to receive a string of characters that represents a single block of data of length determined by the block length value. If onDataReceived was overriden this method will not be called unless the onDataReceived calls this method explicitly using the class and member name.

onConnected()

void core::TCPSession2::onConnected ( )

protectedvirtual

This method is called from within the protocol method when protocol is called on the initial connection where the data is an empty string. Use this method to deliver a message to the connection upon connection.

onDataReceived()

void core::TCPSession2::onDataReceived ( coreutils::ZString &  data )

overrideprotectedvirtual

Override this method to receive data directly from the socket as data is received. If you need data split by line termination characters then override the onLineReceived method instead.

Reimplemented from core::Socket.

onLineReceived()

void core::TCPSession2::onLineReceived ( coreutils::ZString &  line )

protectedvirtual

Override the onLineReceived method to receive a string of characters that represents a single line of data terminated by a LF or CRLF. If onDataReceived was overriden this method will not be called unless the onDataReceived calls this method explicitly using the class and member name.

output()

void core::TCPSession2::output ( std::stringstream &  out )

virtual

The output method is called by a socket session (TCPSession) and will output the detail information for the client socket. When extending BMATCPSocket or BMASession you can override the method to add attributes to the list.

Reimplemented from core::TCPSocket.

protocol()

void core::TCPSession2::protocol ( coreutils::ZString &  data )

protectedvirtual

Override the protocol method to manage and control the session communications in your inherited session. If you do not override this method then the Session default will process the 'commands' added to the server object using the processRequest method on the session input.

When data is received within the session two modes are available to pass the data through the protocol method: LINE or BLOCK.

send()

void core::TCPSession2::send

(

)

The send method is used to output the contents of the out stream to the session containing the stream.

setBlockSize()

void core::TCPSession2::setBlockSize ( int  size = 0 )

protected

Use setBlockSize to set the amount of data that should be read at once from the session data buffer. If this value is set to 0 then the data will be retrieved

terminate()

void core::TCPSession2::terminate

(

)

Use this method to terminate this TCPSession.

Member Data Documentation

out

std::stringstream core::TCPSession2::out

Use out to send data to the session socket or other session sockets.
