Returns the context with which this dispatcher was created.

Specified by:

getContext in interface CommandDispatcher<A extends Comparable<A>,M extends GroupMember<A>>

Returns:

a command execution context

dispatchToMember

public <R,
E extends Exception> CompletionStage<R> dispatchToMember(Command<R,? super C,E> command,
 CacheContainerGroupMember member)
                                                            throws IOException

Description copied from interface: CommandDispatcher

Executes the specified command on the specified group member. If the member has no corresponding dispatcher, the returned completion stage throws a CancellationException.

command - the command to execute

member - the group member on which to execute the command

Returns:

the future result of the command execution

Throws:

IOException - if the command could not be sent
