Package jetbrains.mps.smodel

Class BaseFastNodeFinder

java.lang.Object

jetbrains.mps.smodel.BaseFastNodeFinder

All Implemented Interfaces:

FastNodeFinder

Direct Known Subclasses:

DefaultFastNodeFinder, TransientModelNodeFinder

public class BaseFastNodeFinder
extends Object
implements FastNodeFinder

Base implementation for FastNodeFinder, thread-aware and map update ready. Doesn't track model changes. Model implementation agnostic, doesn't rely on internal SModel implementation

public BaseFastNodeFinder(SModel model)

Method Detail

build

protected BaseFastNodeFinder.ConceptInstanceMap build(Computable<BaseFastNodeFinder.ConceptInstanceMap> b)

Walk associated model and build concept instance map. Subclasses may override e.g. if they need to control read events during the walk.

added

protected void added(SNode n)

Subclasses shall invoke once model had changed

removed

protected void removed(SNode n)

Subclasses shall invoke once model had changed

reset

protected void reset()

Subclasses shall invoke once model had changed

dispose

public void dispose()

Specified by:

dispose in interface FastNodeFinder

getNodes

@NotNull
public List<SNode> getNodes(@NotNull
                            SAbstractConcept concept,
                            boolean includeInherited)

Specified by:

getNodes in interface FastNodeFinder

Returns:

list of instances, or empty list, if none found
