构造器详细资料

BooleanExpressionPredicate

public BooleanExpressionPredicate(CriteriaBuilderImpl criteriaBuilder,
                                  javax.persistence.criteria.Expression<Boolean> expression)

方法详细资料

getExpression

public javax.persistence.criteria.Expression<Boolean> getExpression()

Get the boolean expression defining the predicate.

返回:

The underlying boolean expression.

registerParameters

public void registerParameters(ParameterRegistry registry)

从接口复制的说明: ParameterContainer

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

指定者:

registerParameters 在接口中 ParameterContainer

参数:

registry - The parameter registry with which to register.

render

public String render(boolean isNegated,
                     RenderingContext renderingContext)

从接口复制的说明: PredicateImplementor

Form of Renderable.render(org.hibernate.query.criteria.internal.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.

指定者:

render 在接口中 PredicateImplementor

参数:

isNegated - Should the predicate be negated.

renderingContext - The context for rendering

返回:

The rendered predicate fragment.
