Member Function Documentation

bool LogCabin::Client::TestingCallbacks::stateMachineQuery	(	Protocol::Client::StateMachineQuery_Request &	request,
		Protocol::Client::StateMachineQuery_Response &	response
	)		[virtual]

Handle a read-only state machine query, such as Tree::read or Tree::listDirectory.

The default implementation just returns false.

Parameters:

[in,out]	request	Protocol buffer containing request details. You can modify this and return false to have a slightly different request executed against the in-memory data structure.
[out]	response	Protocol buffer where response details should be filled in if true is returned.

Returns:

True if handled, false to query the in-memory data structure.

bool LogCabin::Client::TestingCallbacks::stateMachineCommand	(	Protocol::Client::StateMachineCommand_Request &	request,
		Protocol::Client::StateMachineCommand_Response &	response
	)		[virtual]

Handle a read-write state machine command, such as Tree::read or Tree::listDirectory.

The default implementation just returns false.

Parameters:

[in,out]	request	Protocol buffer containing request details. You can modify this and return false to have a slightly different request executed against the in-memory data structure.
[out]	response	Protocol buffer where response details should be filled in if true is returned.

Returns:

True if handled, false to query the in-memory data structure.
