NegatedPredicateWrapper

public NegatedPredicateWrapper(PredicateImplementor predicate)

Method Detail

getOperator

public Predicate.BooleanOperator getOperator()

Specified by:

getOperator in interface Predicate

isJunction

public boolean isJunction()

Description copied from interface: PredicateImplementor

Is this a conjunction or disjunction?

Specified by:

isJunction in interface PredicateImplementor

Returns:

true if this predicate is a junction (AND/OR); false otherwise

isNegated

public boolean isNegated()

Specified by:

isNegated in interface Predicate

getExpressions

public List<Expression<Boolean>> getExpressions()

Specified by:

getExpressions in interface Predicate

not

public Predicate not()

Specified by:

not in interface Predicate

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.

render

public String render(RenderingContext renderingContext)

Specified by:

render in interface Renderable

renderProjection

public String renderProjection(RenderingContext renderingContext)

Specified by:

renderProjection in interface Renderable
