Class Retriggers

Object

AbstractBehavior

PrimaryBehavior

Retriggers

All Implemented Interfaces:

Behavior, Proxied

public final class Retriggers
extends PrimaryBehavior

Retriggers behavior.

This behavior is used to trigger the computation of dependent values only when they already exist. It will not create new values.

This behavior supports self-triggering, where the update of a value will trigger the computation of the next existing value for the same Point. This is also supported by the value selection in super which will select the previous value on self-reference.

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. Asks for an other pass if the result Point is not the notice Point.

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.

All of this is prefixed by a preliminary pass to get the next notice when using 'SelectPreviousValue'.

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.

If this is a self-trigger, retriggers the computation of the next value. Otherwiser retriggers the computation of all the results between 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.
