Method Detail

getTargetSModelReference

public abstract SModelReference getTargetSModelReference()

Description copied from interface: SReference

The following two operations are defined only for references which can instantly respond to the request (e.g. they store the target model reference and/or node id as a part of the reference).

Specified by:

getTargetSModelReference in interface SReference

Specified by:

getTargetSModelReference in class SReference

Returns:

target model reference (if available)

setTargetSModelReference

public void setTargetSModelReference(@NotNull
                                     SModelReference modelReference)

isDirect

public boolean isDirect()

makeIndirect

public final boolean makeIndirect()

Overrides:

makeIndirect in class SReference

makeIndirect

public final boolean makeIndirect(boolean force)

It's possible to make reference 'mature' iff both its source and target nodes belong to a model. It's not clear what if these models are not attached to a repository, why would we care to make reference 'indirect' in this case.

Returns:

true when/if reference became 'mature' (i.e. doesn't have target node object but its identity)

makeMature

protected void makeMature()

getResolveInfo

@Nullable
protected String getResolveInfo(SNode immatureNode)
