For Hibernate Reactive

Method Detail

getTiming

public FetchTiming getTiming()

Description copied from interface: Fetch

immediate or delayed? todo (6.0) : should we also expose the fetch-style? Perhaps the fetch-options?

Specified by:

getTiming in interface Fetch

hasTableGroup

public boolean hasTableGroup()

Description copied from interface: Fetch

Is the TableGroup associated with this Fetch defined?

Specified by:

hasTableGroup in interface Fetch

getFetchParent

public FetchParent getFetchParent()

Description copied from interface: Fetch

Obtain the owner of this fetch. Ultimately used to identify the thing that "owns" this fetched navigable for the purpose of:

* identifying the associated owner reference as we process the fetch * inject the fetched instance into the parent and potentially inject the parent reference into the fetched instance if it defines such injection (e.g. Parent)

Specified by:

getFetchParent in interface Fetch

getFetchContainer

public EmbeddableMappingType getFetchContainer()

Specified by:

getFetchContainer in class AbstractFetchParent

getReferencedMappingContainer

public EmbeddableValuedModelPart getReferencedMappingContainer()

Description copied from interface: FetchParent

This parent's mapping type

Specified by:

getReferencedMappingContainer in interface EmbeddableResultGraphNode

Specified by:

getReferencedMappingContainer in interface FetchParent

Overrides:

getReferencedMappingContainer in class AbstractFetchParent

getFetchedMapping

public Fetchable getFetchedMapping()

Description copied from interface: Fetch

The value mapping being fetched

Specified by:

public NavigablePath resolveNavigablePath(Fetchable fetchable)

Specified by:

resolveNavigablePath in interface FetchParent

getReferencedMappingType

public EmbeddableMappingType getReferencedMappingType()

Description copied from interface: FetchParent

This parent's mapping type

Specified by:

getReferencedMappingType in interface EmbeddableResultGraphNode

Specified by:

getReferencedMappingType in interface FetchParent

createAssembler
