Constructor Detail

IdentityLinkPredicate

public IdentityLinkPredicate(IdentityLinkType expectedType,
                             Collection<? extends Id> expectedValues)

Constructs a new predicate instance.

Parameters:

expectedType - the type of identity links used in this predicate

expectedValues - the expected identity link values used in the comparison

Method Detail

getTypePredicate

public Predicate getTypePredicate()

getValuesPredicate

public Predicate getValuesPredicate()

toString

public String toString()

Overrides:

toString in class Object

apply

public Predicate apply(PredicateTransformation transformation)

Description copied from class: Predicate

Applies the given transformation, returning the transformed predicate. If the predicate implementation wraps sub-predicates then this method needs to be overwritten to transform the sub-predicates as well.

Overrides:

apply in class Predicate

Parameters:

transformation - the predicate transformation to be applied

Returns:

the transformed predicate (or the current instance if no transformation was applied)
