Method Detail

getTrigger

public List<JGrapeTrigger<?>> getTrigger(Class<?> domainClass,
                                         JGrapeTrigger.TriggerType type)

Description copied from interface: TriggerProvider

Provides a list of triggers for the specified domain class and trigger type. The list includes triggers specified for all super classes and interfaces. The sequence of triggers are the following:

1. Triggers defined on superclass, Interface triggers before class triggers (recursively from Object.class and down to specified domain class)
2. Local interface triggers (super interface before sub-interface)
3. Triggers defined on specified domain class.

Consider the following class hierarchy: Interface IA Interface IB extends IA Interface IBB class A implements IA class B implements IB, IBB And for each class and interface, one or more registered triggers. The derived trigger list for class B is then:

1. triggers for IA
2. triggers for A
3. triggers for IB
4. triggers for IBB
5. triggers for B

Specified by:

getTrigger in interface TriggerProvider

Parameters:

domainClass - the domain class.

type - the trigger type.

Returns:

the list of triggers for the specified class, including super class triggers and interface triggers.
