Constructor Detail

BooleanAssertionPredicate

public BooleanAssertionPredicate(CriteriaBuilderImpl criteriaBuilder,
                         Expression<Boolean> expression,
                         Boolean assertedValue)

Method Detail

getExpression

public Expression<Boolean> getExpression()

getAssertedValue

public Boolean getAssertedValue()

registerParameters

public void registerParameters(ParameterRegistry registry)

Description copied from interface: ParameterContainer

Register any parameters contained within this query component with the given registry.

Specified by:

registerParameters in interface ParameterContainer

Parameters:

registry - The parameter registry with which to register.

render

public String render(boolean isNegated,
            RenderingContext renderingContext)

Description copied from interface: PredicateImplementor

Form of Renderable.render(org.hibernate.jpa.criteria.compile.RenderingContext) used when the predicate is wrapped in a negated wrapper. Allows passing down the negation flag.

Note that this form is no-op in compound (junction) predicates. The reason being that compound predicates are more complex and the negation is applied during its creation.

Specified by:

render in interface PredicateImplementor

Parameters:

isNegated - Should the predicate be negated.

renderingContext - The context for rendering

Returns:

The rendered predicate fragment.
