java.lang.Object
  org.hibernate.ejb.criteria.AbstractNode
      org.hibernate.ejb.criteria.expression.AbstractTupleElement<X>
          org.hibernate.ejb.criteria.expression.SelectionImpl<T>

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

Type Parameters:

K - The map key type

V - The map value type

All Implemented Interfaces:

Serializable, javax.persistence.criteria.Expression<Map<K,V>>, javax.persistence.criteria.Path<Map<K,V>>, javax.persistence.criteria.Selection<Map<K,V>>, 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>>

Enclosing class:

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".

Method Detail

getAttribute

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

Description copied from interface: PathImplementor

Retrieve reference to the attribute this path represents.

Specified by:

getAttribute in interface PathImplementor<Map<K,V>>

Returns:

The metamodel attribute.

getModel

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

Specified by:

getModel in interface javax.persistence.criteria.Path<Map<K,V>>

getParentPath

public PathImplementor<?> getParentPath()

Description copied from class: AbstractPathImpl

Specified by:

getParentPath in interface javax.persistence.criteria.Path<Map<K,V>>

Overrides:

getParentPath in class AbstractPathImpl<Map<K,V>>

canBeDereferenced

protected boolean canBeDereferenced()

Specified by:

canBeDereferenced in class AbstractPathImpl<Map<K,V>>

locateAttributeInternal

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

Description copied from class: 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.

Specified by:

locateAttributeInternal in class AbstractPathImpl<Map<K,V>>

Parameters:

attributeName - The name of the attribute to locate

Returns:

The attribute; may be null.
