Method Detail

getAttribute

javax.persistence.metamodel.Attribute<?,?> getAttribute()

Retrieve reference to the attribute this path represents.

Returns:

The metamodel attribute.

treatAs

<T extends X> PathImplementor<T> treatAs(java.lang.Class<T> treatAsType)

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

Type Parameters:

T - The parameterized type representation of treatAsType.

Parameters:

treatAsType - The type to treat the path as.

Returns:

The properly typed view of this path.
