Method Detail

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.

getFetchedAttributeDefinition

public AttributeDefinition getFetchedAttributeDefinition()

Description copied from interface: AttributeFetch

Returns the AttributeDefinition for attribute being fetched.

Specified by:

getFetchedAttributeDefinition in interface AttributeFetch

Returns:

The fetched attribute definition.

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. .
