Examples of javax.slee.ChildRelation

javax.slee.ChildRelation
The ChildRelation interface is used by SBBs that require child relationships with other SBBs. Any child-relation accessor method defined in an SBB abstract class must have this interface as its return type.
A ChildRelation object, and any java.util.Iterator objects obtained from it, are only valid within the transaction in which they materialized.
A ChildRelation object conforms to the Java Collections API with the following exceptions:
- The add and addAll methods throw java.lang.UnsupportedOperationException if an attempt is made to modify the collection. The {@link #create create} method should be used instead to add child SBBentities to the collection.
- If an SBB entity is removed from a collection as a result of a clear, remove, removeAll, or retainAll method call on a ChildRelation object, or by a remove method call on a java.util.Iterator object obtained from a ChildRelation object, a cascade delete of the SBB entity tree rooted at the removed SBB entity is initiated. This means that removing an SBB entity from a ChildRelation collection has the same behavior as if the {@link SbbLocalObject#remove remove}method was invoked on the removed SBB entity itself.
If a null parameter is passed to any method, a java.lang.NullPointerException is thrown.
