构造器详细资料

CompoundPredicate

public CompoundPredicate(CriteriaBuilderImpl criteriaBuilder,
                         javax.persistence.criteria.Predicate.BooleanOperator operator)

Constructs an empty conjunction or disjunction.

参数:

criteriaBuilder - The query builder from which this originates.

operator - Indicates whether this predicate will function as a conjunction or disjunction.

CompoundPredicate

public CompoundPredicate(CriteriaBuilderImpl criteriaBuilder,
                         javax.persistence.criteria.Predicate.BooleanOperator operator,
                         javax.persistence.criteria.Expression<Boolean>... expressions)

Constructs a conjunction or disjunction over the given expressions.

参数:

criteriaBuilder - The query builder from which this originates.

operator - Indicates whether this predicate will function as a conjunction or disjunction.

expressions - The expressions to be grouped.

CompoundPredicate

public CompoundPredicate(CriteriaBuilderImpl criteriaBuilder,
                         javax.persistence.criteria.Predicate.BooleanOperator operator,
                         List<javax.persistence.criteria.Expression<Boolean>> expressions)

Constructs a conjunction or disjunction over the given expressions.

参数:

criteriaBuilder - The query builder from which this originates.

operator - Indicates whether this predicate will function as a conjunction or disjunction.

expressions - The expressions to be grouped.

方法详细资料

getOperator

public javax.persistence.criteria.Predicate.BooleanOperator getOperator()

指定者:

getOperator 在接口中 javax.persistence.criteria.Predicate

getExpressions

public List<javax.persistence.criteria.Expression<Boolean>> getExpressions()

指定者:

getExpressions 在接口中 javax.persistence.criteria.Predicate

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(RenderingContext renderingContext)

从接口复制的说明: Renderable

Perform the rendering, returning the rendition

指定者:

render 在接口中 Renderable

isJunction

public boolean isJunction()

从接口复制的说明: PredicateImplementor

Is this a conjunction or disjunction?

指定者:

isJunction 在接口中 PredicateImplementor

返回:

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

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.

not

public javax.persistence.criteria.Predicate not()

Create negation of compound predicate by using logic rules: 1. not (x || y) is (not x && not y) 2. not (x && y) is (not x || not y)

指定者:

not 在接口中 javax.persistence.criteria.Predicate

覆盖:

not 在类中 AbstractPredicateImpl

reverseOperator

public static javax.persistence.criteria.Predicate.BooleanOperator reverseOperator(javax.persistence.criteria.Predicate.BooleanOperator operator)

render

public static String render(PredicateImplementor predicate,
                            RenderingContext renderingContext)
