Class Members.Member<X,​Y>

  • Type Parameters:
    X - The type that contains this attribute
    Y - The type of this attribute
    All Implemented Interfaces:
    jakarta.persistence.metamodel.Attribute<X,​Y>, java.lang.Comparable<Members.Member<X,​Y>>
    Direct Known Subclasses:
    Members.PluralAttributeImpl, Members.SingularAttributeImpl
    Enclosing class:

    public abstract static class Members.Member<X,​Y>
extends java.lang.Object
implements jakarta.persistence.metamodel.Attribute<X,​Y>, java.lang.Comparable<Members.Member<X,​Y>>
    An attribute of a Java type. A persistent attribute is realized as a field and getter/setter method of a Java class. This implementation adapts kernel's FieldMetaData construct to meet the JPA API contract.
