方法详细资料

getAttribute

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

Retrieve reference to the attribute this path represents.

返回:

The metamodel attribute.

treatAs

<T extends X> PathImplementor<T> treatAs(Class<T> treatAsType)

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

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.
