Constructor Detail

CompositePredicate

public CompositePredicate(CompositePredicate.Operator operator,
                          Collection<? extends Predicate> predicates)

Creates a predicate instance which concatenates the given predicates with the specified operator.

Parameters:

predicates - all predicates to be concatenated

operator - the logical operator

Method Detail

getOperator

public CompositePredicate.Operator getOperator()

The logical operator which defines the type of concatenation.

Returns:

the operator

getPredicates

public com.google.common.collect.ImmutableList<Predicate> getPredicates()

All predicates to be concatenated.

Returns:

the predicates;

createRenderingModePredicate

public RenderingModePredicate createRenderingModePredicate(RenderingMode renderingMode)

Description copied from class: RenderingModePredicate

create the same predicate but with given renderingMode flag

Specified by:

createRenderingModePredicate in class RenderingModePredicate

Parameters:

renderingMode - flag to set in the predicate

Returns:

new renderingModePredicate which is the same as the original one but with the enforced renderingFlag

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)
