Method Detail

getNavigablePath

public NavigablePath getNavigablePath()

Description copied from interface: Fetch

Get the property path to this fetch

Specified by:

getNavigablePath in interface DomainResultGraphNode

Specified by:

getNavigablePath in interface Fetch

Returns:

The property path

getReferencedPath

public NavigablePath getReferencedPath()

Description copied from interface: BiDirectionalFetch

The NavigablePath for the DomainResult or Fetch that this Fetch refers to. For `o`, the referenced path is `p`. For `oa`, it's `p.address` Different from Fetch.getNavigablePath() which returns this fetch's path, i.e. `p.address.owner` and `p.address.owner.address` respectively

Specified by:

getReferencedPath in interface BiDirectionalFetch

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)

Create the assembler for this fetch

Specified by:
