  +--alice.respect.Reactor

All Implemented Interfaces:

Reactor

public class Reactor

extends java.lang.Object

implements Reactor

this class defines the ReSpecT tuple centre reactor component.

the specified reactions are parsed and executed using tuProlog engines.

Constructor Summary

Reactor(TupleCentreVM m)

Method Summary

static LogicTuple	checkReactionSpec(LogicTuple spec)
boolean	evalReaction(TriggeredReaction z) reaction exectution is realized solving the goal represented by reaction body
java.lang.String	getOutTCactivityClassFile()
Tuple	getReactionSpec() Gets the current reactive behaviour of the tuple centre
alice.tuprolog.Term	getTerm(Event ev)
java.util.ArrayList	getTriggeredReactions(Event ev) the triggered reactions are collected the tuProlog engine, finding all the solutions of the requested goal
void	onNewVMStableState() invoked by the tuple centre virtual machine when stable state is reached
void	reset() Resets the reactive component of the machine
void	setOutTCactivityClassFile(java.lang.String classFile)
boolean	setReactionSpec(Tuple spec) Sets the specification describing the reactive behaviour It's like the program specyfing the behaviour of the tuple centre reacting to communication events.
boolean	triggerReaction(Event ev) Checks if any reaction is triggered by a communication event

Method Detail

reset

public void reset()

Description copied from interface: Reactor

Resets the reactive component of the machine

Specified by:

reset in interface Reactor

getTriggeredReactions

public java.util.ArrayList getTriggeredReactions(Event ev)

the triggered reactions are collected the tuProlog engine, finding all the solutions of the requested goal

Specified by:

getTriggeredReactions in interface Reactor

Following copied from interface: alice.tuplemedium.Reactor

Parameters:

ev - the event triggering reactions

Returns:

the triggered reactions

triggerReaction

public boolean triggerReaction(Event ev)

Description copied from interface: Reactor

Specified by:

triggerReaction in interface Reactor

Following copied from interface: alice.tuplemedium.Reactor

Parameters:

ev - the event triggering reactions

Returns:

the triggered reactions

evalReaction

public boolean evalReaction(TriggeredReaction z)

reaction exectution is realized solving the goal represented by reaction body

Specified by:

evalReaction in interface Reactor

Following copied from interface: alice.tuplemedium.Reactor

Parameters:

z - the triggered reaction to be evaluated

Returns:

true if the evaluation has been successful, false if not

getTerm
