Constructor Detail

PluralAttributePath

public PluralAttributePath(CriteriaBuilderImpl criteriaBuilder,
                           PathSource source,
                           javax.persistence.metamodel.PluralAttribute<?,X,?> attribute)
Method Detail

getAttribute

public javax.persistence.metamodel.PluralAttribute<?,X,?> getAttribute()
Description copied from interface: PathImplementor
Retrieve reference to the attribute this path represents.

Specified by:
getAttribute in interface PathImplementor<X>
Returns:
The metamodel attribute.

getPersister

public CollectionPersister getPersister()

canBeDereferenced

protected boolean canBeDereferenced()
Specified by:
canBeDereferenced in class AbstractPathImpl<X>

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<X>
Parameters:
attributeName - The name of the attribute to locate
Returns:
The attribute; may be null.

getModel

public javax.persistence.metamodel.Bindable<X> getModel()
Specified by:
getModel in interface javax.persistence.criteria.Path<X>
