@Incubating
public interface Fetch
extends DomainResultGraphNode

Contract for fetches including entity, collection and composite. Acts as the producer for the DomainResultAssembler for this result as well as any Initializer instances needed

Method Summary

Modifier and Type	Method	Description
default boolean	containsAnyNonScalarResults()	Does this node contain any non-scalar (sub-)results?
DomainResultAssembler<?>	createAssembler(FetchParentAccess parentAccess, AssemblerCreationState creationState)	Create the assembler for this fetch
Fetchable	getFetchedMapping()	The value mapping being fetched
FetchParent	getFetchParent()	Obtain the owner of this fetch.
NavigablePath	getNavigablePath()	Get the property path to this fetch
FetchTiming	getTiming()	immediate or delayed? todo (6.0) : should we also expose the fetch-style? Perhaps the fetch-options?
boolean	hasTableGroup()	Is the TableGroup associated with this Fetch defined?

Method Detail

getNavigablePath

NavigablePath getNavigablePath()

Get the property path to this fetch

Specified by:

getNavigablePath in interface DomainResultGraphNode

Returns:

The property path

getFetchParent

FetchParent getFetchParent()

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)

getFetchedMapping

Fetchable getFetchedMapping()

The value mapping being fetched

getTiming

FetchTiming getTiming()

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

hasTableGroup

boolean hasTableGroup()

Is the TableGroup associated with this Fetch defined?

containsAnyNonScalarResults

default boolean containsAnyNonScalarResults()

Description copied from interface: DomainResultGraphNode

Does this node contain any non-scalar (sub-)results?

Specified by:

containsAnyNonScalarResults in interface DomainResultGraphNode

createAssembler

DomainResultAssembler<?> createAssembler(FetchParentAccess parentAccess,
                                         AssemblerCreationState creationState)

Create the assembler for this fetch
