Type Parameters:

Direct Known Subclasses:

CommandReactOnce

public abstract class CommandReact<COMMAND extends CommandMessage>
extends java.lang.Object

This abstract class allows you to easily hook a specific outgoing-command-handling behavior. It automatically register a listener for a specified CommandMessage for you and calls react(CommandMessage) method automatically.

If you need to react only once to the event, use EventReactOnce.

Use EventReact.enable() and EventReact.disable() to enable react / disable react. The reaction is enabled as default.

WARNING:Use as anonymous class, but save it as a field of your class! Note, that we're using weak-references to listeners and if you do not save pointer to the object, it will be gc()ed!
