Method Summary

Modifier and Type	Method and Description
Type	getDiscriminatorType() Access to the type of the value that makes up the discriminator portion of the AnyType.
Type	getIdentifierType() Access to the type of the value that makes up the identifier portion of the AnyType.
Iterable<AnyMappingDefinition.DiscriminatorMapping>	getMappingDefinedDiscriminatorMappings() Access to discriminator mappings explicitly defined in the mapping metadata.
AnyType	getType() Access to the mapping's AnyType

Method Detail

getType

AnyType getType()

Access to the mapping's AnyType

Returns:

The AnyType

isLazy

boolean isLazy()

Was the mapping defined as lazy?

Returns:

true/false

getIdentifierType

Type getIdentifierType()

Access to the type of the value that makes up the identifier portion of the AnyType.

Returns:

The identifier type

See Also:

AnyMetaDef.idType()

getDiscriminatorType

Type getDiscriminatorType()

Access to the type of the value that makes up the discriminator portion of the AnyType. The discriminator is historically called the "meta".

NOTE : If explicit discriminator mappings are given, the type here will be a MetaType.

Returns:

The discriminator type

See Also:

Any.metaColumn(), AnyMetaDef.metaType()

getMappingDefinedDiscriminatorMappings

Iterable<AnyMappingDefinition.DiscriminatorMapping> getMappingDefinedDiscriminatorMappings()

Access to discriminator mappings explicitly defined in the mapping metadata. There are 2 flavors of discrimination:

1. The database holds the concrete entity names. This is an implicit form, meaning that the discriminator mappings do not have to be defined in the mapping metadata. In this case, an empty iterable is returned here
2. The database holds discriminator values that are interpreted to corresponding entity names based on discriminator mappings explicitly supplied in the mapping metadata (see AnyMetaDef.metaValues()). In this case, this method gives access to those explicitly defined mappings.

Returns:

The explicitly defined discriminator value mappings.
