方法详细资料

hasFetches

public boolean hasFetches()

从接口复制的说明: EntityIdentifierDescription

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

指定者:

hasFetches 在接口中 EntityIdentifierDescription

返回:

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

hasBidirectionalEntityReferences

public boolean hasBidirectionalEntityReferences()

从接口复制的说明: EntityIdentifierDescription

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

指定者:

hasBidirectionalEntityReferences 在接口中 EntityIdentifierDescription

返回:

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

getSource

public FetchSource getSource()

从接口复制的说明: Fetch

Obtain the owner of this fetch.

指定者:

getSource 在接口中 Fetch

返回:

The fetch owner.

getFetchedType

public Type getFetchedType()

从接口复制的说明: Fetch

Get the Hibernate Type that describes the fetched attribute

指定者:

getFetchedType 在接口中 Fetch

返回:

The Type of the fetched attribute

isNullable

public boolean isNullable()

从接口复制的说明: Fetch

Is this fetch nullable?

指定者:

isNullable 在接口中 Fetch

返回:

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

resolveEntityReference

public EntityReference resolveEntityReference()

从接口复制的说明: 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.

指定者:

resolveEntityReference 在接口中 FetchSource

返回:

the "current" EntityReference or null if none. .
