接口 HibernateCriteriaBuilder

所有超级接口:

javax.persistence.criteria.CriteriaBuilder

所有已知实现类:

CriteriaBuilderImpl

public interface HibernateCriteriaBuilder
extends javax.persistence.criteria.CriteriaBuilder

Hibernate extensions to the JPA CriteriaBuilder. Currently there are no extensions; these are coming in 6.0

方法详细资料

isMapEmpty

<M extends Map<?,?>> javax.persistence.criteria.Predicate isMapEmpty(javax.persistence.criteria.Expression<M> mapExpression)

Create a predicate that tests whether a Map is empty.

NOTE : Due to type-erasure we cannot name this the same as CriteriaBuilder.isEmpty(javax.persistence.criteria.Expression<C>)

参数:

mapExpression - The expression resolving to a Map which we want to check for emptiness

返回:

is-empty predicate

isMapNotEmpty

<M extends Map<?,?>> javax.persistence.criteria.Predicate isMapNotEmpty(javax.persistence.criteria.Expression<M> mapExpression)

Create a predicate that tests whether a Map is not empty.

NOTE : Due to type-erasure we cannot name this the same as CriteriaBuilder.isNotEmpty(javax.persistence.criteria.Expression<C>)

参数:

mapExpression - The expression resolving to a Map which we want to check for non-emptiness

返回:

is-not-empty predicate

mapSize

<M extends Map<?,?>> javax.persistence.criteria.Expression<Integer> mapSize(javax.persistence.criteria.Expression<M> mapExpression)

Create an expression that tests the size of a map.

NOTE : Due to type-erasure we cannot name this the same as CriteriaBuilder.size(javax.persistence.criteria.Expression<C>)

参数:

mapExpression - The expression resolving to a Map for which we want to know the size

返回:

size expression

mapSize

<M extends Map<?,?>> javax.persistence.criteria.Expression<Integer> mapSize(M map)

Create an expression that tests the size of a map.

参数:

map - The Map for which we want to know the size

返回:

size expression
