Method Detail

criteriaBuilder

CriteriaBuilderImpl criteriaBuilder()

Access to the CriteriaBuilder

Returns:

The CriteriaBuilder

isJunction

boolean isJunction()

Is this a conjunction or disjunction?

Returns:

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

render

java.lang.String render(boolean isNegated,
                        RenderingContext renderingContext)

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.

Parameters:

isNegated - Should the predicate be negated.

renderingContext - The context for rendering

Returns:

The rendered predicate fragment.
