java.lang.Object

org.hibernate.query.criteria.internal.AbstractNode

org.hibernate.query.criteria.internal.expression.AbstractTupleElement<X>

org.hibernate.query.criteria.internal.expression.SelectionImpl<T>

org.hibernate.query.criteria.internal.expression.ExpressionImpl<X>

org.hibernate.query.criteria.internal.path.AbstractPathImpl<Map<K,V>>

org.hibernate.query.criteria.internal.path.MapKeyHelpers.MapKeySource<K,V>

类型参数:

K - The map key type

V - The map value type

所有已实现的接口:

Serializable, javax.persistence.criteria.Expression<Map<K,V>>, javax.persistence.criteria.Path<Map<K,V>>, javax.persistence.criteria.Selection<Map<K,V>>, javax.persistence.TupleElement<Map<K,V>>, ExpressionImplementor<Map<K,V>>, ParameterContainer, PathImplementor<Map<K,V>>, PathSource<Map<K,V>>, Renderable, SelectionImplementor<Map<K,V>>, TupleElementImplementor<Map<K,V>>

封闭类:

MapKeyHelpers

public static class MapKeyHelpers.MapKeySource<K,V>
extends AbstractPathImpl<Map<K,V>>
implements PathImplementor<Map<K,V>>, Serializable

Defines a path for the map which can then be used to represent the source of the map key "attribute".

MapKeySource

public MapKeySource(CriteriaBuilderImpl criteriaBuilder,
                    Class<Map<K,V>> javaType,
                    MapJoinImplementor<?,K,V> mapJoin,
                    javax.persistence.metamodel.MapAttribute<?,K,V> attribute)

方法详细资料

getAttribute

public javax.persistence.metamodel.MapAttribute<?,K,V> getAttribute()

从接口复制的说明: PathImplementor

Retrieve reference to the attribute this path represents.

指定者:

getAttribute 在接口中 PathImplementor<K>

返回:

The metamodel attribute.

getModel

public javax.persistence.metamodel.Bindable<Map<K,V>> getModel()

指定者:

getModel 在接口中 javax.persistence.criteria.Path<K>

getParentPath

public PathImplementor<?> getParentPath()

指定者:

getParentPath 在接口中 javax.persistence.criteria.Path<K>

覆盖:

getParentPath 在类中 AbstractPathImpl<Map<K,V>>

canBeDereferenced

protected boolean canBeDereferenced()

指定者:

canBeDereferenced 在类中 AbstractPathImpl<Map<K,V>>

locateAttributeInternal

protected javax.persistence.metamodel.Attribute locateAttributeInternal(String attributeName)

从类复制的说明: AbstractPathImpl

Get the attribute by name from the underlying model. This allows subclasses to define exactly how the attribute is derived. Called from AbstractPathImpl.locateAttribute(java.lang.String) which also applies nullness checking for proper error reporting.

指定者:

locateAttributeInternal 在类中 AbstractPathImpl<Map<K,V>>

参数:

attributeName - The name of the attribute to locate

返回:

The attribute; may be null.

treatAs

public <T extends Map<K,V>> PathImplementor<T> treatAs(Class<T> treatAsType)

从接口复制的说明: PathImplementor

Defines handling for the JPA 2.1 TREAT down-casting feature.

指定者:

treatAs 在接口中 PathImplementor<K>

类型参数:

T - The parameterized type representation of treatAsType.

参数:

treatAsType - The type to treat the path as.

返回:

The properly typed view of this path.

getPathIdentifier

public String getPathIdentifier()

从接口复制的说明: PathSource

Get the string representation of this path as a navigation from one of the queries identification variables

指定者:

getPathIdentifier 在接口中 PathSource<K>

覆盖:

getPathIdentifier 在类中 AbstractPathImpl<Map<K,V>>

返回:

The path's identifier.

prepareAlias

public void prepareAlias(RenderingContext renderingContext)

指定者:

prepareAlias 在接口中 PathSource<K>

覆盖:

prepareAlias 在类中 AbstractPathImpl<Map<K,V>>
