Detailed Description

Defines the interface that xmog_jvm uses to communicate with a server.

The lack of uniformity between connector/stream pairs among the possible IPC types that xmog may want to use (TCP, UDP, UNIX pipe, MEM_Stream, etc.) make a strategy the best way to approach this. Since there is a limited number of operations that xmog_jvm needs to take advantage of, it's easier to encapsulate them behind a strategy than to try to ifdef things elsewhere. This class defines an interface which other strategy classes representing the actual IPC mechanisms need to inherit from.

Member Function Documentation

connect()

virtual int xmog_i_comm_strategy::connect ( const ACE_TCHAR *  dest, const ACE_Time_Value *  timeout = 0  )

pure virtual

Connect to a peer identified by dest.

Parameters

dest	The address of the peer. Derived classes determine what form this should be in.

Return values

0	for success
-1	for failure.

Implemented in xmog_i_comm_tcp.

disconnect()

virtual void xmog_i_comm_strategy::disconnect ( void  )

pure virtual

Disconnect from the peer.

Implemented in xmog_i_comm_tcp.

get_handle()

virtual ACE_HANDLE xmog_i_comm_strategy::get_handle ( void  )

pure virtual

Obtain the IPC handle for this strategy. This is a handle that can be registered with an ACE_Reactor for INPUT, OUTPUT events.

Implemented in xmog_i_comm_tcp.

recv()

virtual int xmog_i_comm_strategy::recv ( ACE_Message_Block &  b )

pure virtual

Receive data into the specified ACE_Message_Block from the peer.

Parameters

b	ACE_Message_Block to store data. Data is placed starting at the block's wr_ptr. b.space() is used to get the max amount of data to receive. wr_ptr is updated to reflect received data.

Return values

0	Success.
-1	Failure.

Implemented in xmog_i_comm_tcp.

send()

virtual int xmog_i_comm_strategy::send ( ACE_Message_Block &  b )

pure virtual

Send data in the specified ACE_Message_Block to the peer.

Parameters

b	ACE_Message_Block to send. Data is sent starting at the block's rd_ptr. b.length() is used to get the amount of data to send. rd_ptr is updated to reflect sent data.

Return values

0	Success.
-1	Failure.

Implemented in xmog_i_comm_tcp.
