public class TriggerImpl

extends java.lang.Object

implements Trigger

Provides the basic implementation for the trigger classes. (setting parameters, types)

protected long	end
protected boolean	is_periodical
protected long	next The update number of the next time when it should run.
protected long	start
protected long	step

Constructor Summary

TriggerImpl()

Method Summary

protected void	adjustPeriodicalSchedule() This method shoulb be invoked after execution if the trigger is periodical.
void	execute() This method should be overridden by the concrete implementations.
void	initialize(java.util.StringTokenizer params) Sets the type and the scheduling information according to the type.
void	setParameters(java.util.StringTokenizer st) Should be overridden in implementations.
boolean	shouldBeExecuted(long up_date) If the current update number equals the next time then it should execute.
boolean	shouldBeRemoved() If it's not periodical or it passed its end value then it should be removed.

Method Detail

shouldBeRemoved

public boolean shouldBeRemoved()

If it's not periodical or it passed its end value then it should be removed.

Specified by:

shouldBeRemoved in interface Trigger

shouldBeExecuted

public boolean shouldBeExecuted(long up_date)

If the current update number equals the next time then it should execute.

Specified by:

shouldBeExecuted in interface Trigger

Following copied from interface: physis.core.triggers.Trigger

Parameters:

update_count - The number of already performed updates. A trigger may ignore this information if its execution doesn't depend on time but some other conditions.

execute

public void execute()

This method should be overridden by the concrete implementations.

Specified by:

execute in interface Trigger

adjustPeriodicalSchedule

protected void adjustPeriodicalSchedule()

This method shoulb be invoked after execution if the trigger is periodical.

initialize

public void initialize(java.util.StringTokenizer params)

Sets the type and the scheduling information according to the type.

Specified by:

initialize in interface Trigger

setParameters

public void setParameters(java.util.StringTokenizer st)

Should be overridden in implementations.

Specified by:

setParameters in interface Trigger
