Class AlwaysTriggers

Object

AbstractBehavior

PrimaryBehavior

AlwaysTriggers

All Implemented Interfaces:

Behavior, Proxied

public final class AlwaysTriggers
extends PrimaryBehavior

Always triggers behavior.

Always triggers the computation of a result with the same timestamp as the notice. It also retriggers the computation of subsequent dependents up to the next appearance of itself.

Method Detail

isResultFetched

public boolean isResultFetched(PointValue noticeValue,
                               ResultValue resultValue)

Asks if result value has been fetched.

Specified by:

isResultFetched in interface Behavior

Overrides:

isResultFetched in class AbstractBehavior

Parameters:

noticeValue - The triggering point value

resultValue - The the result value.

Returns:

True if the result value has been fetched.

prepareTrigger

public boolean prepareTrigger(PointValue noticeValue,
                              Batch batch)

Allows a behavior to prepare for a call to Behavior.trigger(org.rvpf.base.value.PointValue, org.rvpf.metadata.processor.Batch).

Will be called until all the batch behaviors return true.

On the first pass, asks for the next notice.

On the second pass, if there is a next notice, asks for all the results between this notice and the next. Otherwise, asks for all the results at or after the notice.

Specified by:

prepareTrigger in interface Behavior

Overrides:

prepareTrigger in class AbstractBehavior

Parameters:

noticeValue - A point value acting as potential trigger.

batch - The current batch context.

Returns:

True if ready for trigger.

trigger

public void trigger(PointValue noticeValue,
                    Batch batch)

Triggers the computation of results if needed.

This is called after all the calls to the Behavior.prepareTrigger(org.rvpf.base.value.PointValue, org.rvpf.metadata.processor.Batch) method have returned true.

Sets up a result at the notice's time.

Also retriggers the computation of all the results btween this notice and the next, defaulting to the end of time.

Specified by:

trigger in interface Behavior

Overrides:

trigger in class AbstractBehavior

Parameters:

noticeValue - A point value acting as potential trigger.

batch - The current batch context.

doValidate

protected boolean doValidate()

Does validate this behavior.

Overrides:

doValidate in class AbstractBehavior

Returns:

True when valid.
