Class Trigger

java.lang.Object
oracle.as.scheduler.BaseMetadata<Trigger>
oracle.as.scheduler.Trigger

All Implemented Interfaces:

java.io.Serializable

public class Trigger

extends BaseMetadata<Trigger>

implements java.io.Serializable

This class encapsulate the definition of a trigger for event based scheduling. Similar to the time-based scheduling that is defined by a Schedule definition, the event-based scheduling is defined by a Trigger definition. A Trigger definition defines what events the associated request depends on for execution. It also provides support for specifying event filters.

Constructor Detail

Trigger

public Trigger(java.lang.String name,
               java.lang.String displayNameKey,
               java.lang.String descriptionKey,
               org.w3c.dom.Document expression,
               Filter[] filters,
               java.lang.String[] resourceBundleIDs)

Constructs a new instance and associate resource bundles

Parameters:

name - - the name for the new Trigger object. The name is also used as the default display name unless otherwise specifially set.

displayNameKey - - the key of the entry in the resourcebundles to lookup the name. Optional

descriptionKey - - the key of the entry in the resourcebundles to lookup the description. Optional.

expression - the XML document fragment representing the trigger expression

filters - the list of event filters. These filters are only used to select what events are of interest to the trigger. Each filter is meant to select one event.

A filter used for this purpose can include up to one operator. That operator is assumed to be Operator.AND. The only fields supported are Event.NAME and Event.TYPE. The comparison operator between the different filters in the array is OR.

resourceBundleIDs - -- an array of resource bundle id. Optional

Trigger

public Trigger(java.lang.String name,
               java.lang.String description,
               org.w3c.dom.Document expression,
               Filter[] filters)

Constructs a new instance

Parameters:

name - - the name for the new Trigger object. The name is also used as the default display name unless otherwise specifially set.

description - - optional description to be associated with the new Trigger.

expression - the XML document fragment representing the trigger expression

filters - the list of event filters. These filters are only used to select what events are of interest to the trigger. Each filter is meant to select one event.

A filter used for this purpose can include up to one operator. That operator is assumed to be Operator.AND. The only fields supported are Event.NAME and Event.TYPE. The comparison operator between the different filters in the array is OR.

Trigger

protected Trigger(java.lang.String name,

                  Filter[] filters,
                  MetadataObjectId objectId)

INTERNAL USE ONLY Constructs a new instance

Parameters:

name - - the name for the new Trigger object. The name is also used as the default display name unless otherwise specifially set.

description - - optional description to be associated with the new Trigger.

expression - the XML document fragment representing the trigger expression

filters - the list of event filters. These filters are only used to select what events are of interest to the trigger. Each filter is meant to select one event.
