IChainedCommandHandler<T>.GetCommandState Method

Definition

Called to determine the state of the command. This method should never return Unspecified as it would prevent calling following command handlers. nextCommandHandler should be called instead. If a IChainedCommandHandler<T> handles a command it doesn't own, its GetCommandState(T, Func<CommandState>) should always call nextCommandHandler" to give a chance a ICommandHandler that owns the command to enable or disable it.
