Element Detail

value

public abstract String value

Specifies the name of the corresponding attribute.

Returns:

value

subgraph

public abstract String subgraph

Refers to a NamedSubgraph specification that further characterizes an attribute node corresponding to a managed type (entity or embeddable). The value of the subgraph element must correspond to the name used for the subgraph in the NamedSubgraph element. If the referenced attribute is an entity which has entity subclasses, there may be more than one NamedSubgraph element with this name, and the subgraph element is considered to refer to all of these.

Returns:

subgraph

Default:

""

keySubgraph

public abstract String keySubgraph

Refers to a NamedSubgraph specification that further characterizes an attribute node corresponding to the key of a Map-valued attribute. The value of the the keySubgraph element must correspond to the name used for the subgraph in the NamedSubgraph element. If the referenced attribute is an entity which has entity subclasses, there may be more than one NamedSubgraph element with this name, and the keySubgraph element is considered to refer to all of these.

Returns:
