cz.cuni.amis.pogamut.base.communication.command.react
Class CommandReactOnce<COMMAND extends CommandMessage>

java.lang.Object
  cz.cuni.amis.pogamut.base.communication.command.react.CommandReact<COMMAND>
      cz.cuni.amis.pogamut.base.communication.command.react.CommandReactOnce<COMMAND>

Type Parameters:

COMMAND -

public abstract class CommandReactOnce<COMMAND extends CommandMessage>
extends CommandReact<COMMAND>

This abstract class allows you to easily hook a specific event-handling behavior. It automatically register a listener for a specified IWorldCommand for you and calls CommandReactOnce#react(IWorldCommand) method automatically. The CommandReactOnce#react(IWorldCommand) will be called only once (upon first event received).

If you need to react every time, use CommandReact.

Use CommandReact.enable() and CommandReact.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!
