Method Detail

hasFetches

public boolean hasFetches()

Description copied from interface: EntityIdentifierDescription

Can this EntityIdentifierDescription be treated as a FetchSource and if so does it have any fetches?

Specified by:

hasFetches in interface EntityIdentifierDescription

Returns:

true iff this can be cast to FetchSource and (after casting) it returns non-empty results for FetchSource.getFetches()

hasBidirectionalEntityReferences

public boolean hasBidirectionalEntityReferences()

Description copied from interface: EntityIdentifierDescription

Can this EntityIdentifierDescription be treated as a FetchSource and if so does it have any bidirectional entity references?

Specified by:

hasBidirectionalEntityReferences in interface EntityIdentifierDescription

Returns:

true iff this can be cast to FetchSource and (after casting) it returns non-empty results for FetchSource.getBidirectionalEntityReferences()

getSource

public FetchSource getSource()

Description copied from interface: Fetch

Obtain the owner of this fetch.

Specified by:

getSource in interface Fetch

Returns:

The fetch owner.

getFetchedType

public Type getFetchedType()

Description copied from interface: Fetch

Get the Hibernate Type that describes the fetched attribute

Specified by:

getFetchedType in interface Fetch

Returns:

The Type of the fetched attribute

isNullable

public boolean isNullable()

Description copied from interface: Fetch

Is this fetch nullable?

Specified by:

isNullable in interface Fetch

Returns:

true, if this fetch is nullable; false, otherwise.

resolveEntityReference

public EntityReference resolveEntityReference()

Description copied from interface: FetchSource

Resolve the "current" EntityReference, or null if none. If this object is an EntityReference, then this object is returned; otherwise, if this object is a Fetch, then the nearest EntityReference will be resolved from its source, if possible. If no EntityReference can be resolved, null is return.

Specified by:

resolveEntityReference in interface FetchSource

Returns:

the "current" EntityReference or null if none. .

Fetch.getSource().
