Method Detail

throwExceptionIfCallerDisconnected

void throwExceptionIfCallerDisconnected(String regionName)
                                        throws CallerDisconnectedException

Throw an exception if the caller who made this IPC call has disconnected. If called from outside the context of IPC, this does nothing.

Throws:

CallerDisconnectedException

isClientCellBlockSupport

boolean isClientCellBlockSupport()

If the client connected and specified a codec to use, then we will use this codec making cellblocks to return. If the client did not specify a codec, we assume it does not support cellblocks and will return all content protobuf'd (though it makes our serving slower). We need to ask this question per call because a server could be hosting both clients that support cellblocks while fielding requests from clients that do not.

Returns:

True if the client supports cellblocks, else return all content in pb
