Method Summary

protected abstract AnnotationSet	doMatch(Annotation annot, AnnotationSet as)
boolean	doMatch(Object annotValue, AnnotationSet context) Sets up environment for concreate class to do the specific matching check
protected Collection<Annotation>	filterMatches(AnnotationSet containedSet) If there are attribute constraints, filter the set.
void	setValue(Object v) If the given value is a Constraint, then check if there are any additional attribute/feature-checks on the constraint.

EmbeddedConstraintPredicate

                                   Object value)

Method Detail

doMatch

public boolean doMatch(Object annotValue,
                       AnnotationSet context)
                throws JapeException

Sets up environment for concreate class to do the specific matching check

Specified by:

doMatch in class AbstractConstraintPredicate

Throws:

JapeException

doMatch

protected abstract AnnotationSet doMatch(Annotation annot,
                                         AnnotationSet as)

filterMatches

protected Collection<Annotation> filterMatches(AnnotationSet containedSet)

If there are attribute constraints, filter the set.

Parameters:

containedSet -

Returns:

setValue

public void setValue(Object v)

If the given value is a Constraint, then check if there are any additional attribute/feature-checks on the constraint. If so, then store the constraint for use during matching calls. If not, then only the annotation type for the constraint is stored since the full constraint is not needed.

Specified by:

setValue in interface ConstraintPredicate

Overrides:

setValue in class AbstractConstraintPredicate
