Class UbiquitousReaction

java.lang.Object
  lime.Reaction
      lime.UbiquitousReaction

All Implemented Interfaces:

java.io.Serializable

public class UbiquitousReaction

extends Reaction

Specifies reactions that are location-independent and get installed on the whole shared tuple space. In other words, these reactions are installed on every node in the system (i.e., those currently present and, upon engagement, also on the new ones).

This kind of reaction can be used only to define weak reaction operations, using the LimeTupleSpace.addWeakReaction method. Strong reactions require LocalizedReactions to be passed to the addStrongReaction method.

Constructor Detail

UbiquitousReaction

public UbiquitousReaction(LimeTemplate template,
                          ReactionListener listener,
                          short mode)

Create the reaction.

Parameters:

template - tuples in the shared tuple space that match this template will trigger execution of the reaction, i.e., invocation of the listener.

listener - the reaction listener, which specifies the computation to take place when the reaction is fired.

mode - the reaction mode (see Reaction).
