Class TrivialModelDescriptor

java.lang.Object

jetbrains.mps.extapi.model.SModelDescriptorStub

jetbrains.mps.extapi.model.SModelBase

jetbrains.mps.smodel.TrivialModelDescriptor

All Implemented Interfaces:

ModelWithDisposeInfo, FastNodeFinder.Factory, SModelInternal, SModel

Direct Known Subclasses:

LanguageDescriptorModelProvider.LanguageModelDescriptor

public class TrivialModelDescriptor
extends SModelBase

Model openapi.SModel implementation to parasitize on (utilize) existing SModelBase and smodel.SModel classes. It takes existing SModelData and provides it to outer world through openapi.SModel. Perhaps, parts of SModelBase could move to SModelDescriptorStub, and this class could use SModelDescriptorStub then. FIXME move to [smodel] once SModelBase cease to depend on [kernel] stuff FIXME why doesn't it support add/remove root operations? Was it intentional, or just overlook?

Constructor Detail

TrivialModelDescriptor

public TrivialModelDescriptor(@NotNull
                              SModel modelData)

Parameters:

modelData - actual model data represented with this descriptor. Note, data's modelDescriptor is set to this

Method Detail

getSModelInternal

public SModel getSModelInternal()

Description copied from class: SModelDescriptorStub

Migration to 3.0. Loads and returns model data. FIXME Replace uses of this method with getSModel(), make it abstract and implement in SModelBase subclasses. The name getSModelInternal is misleading as it clashes with SModelInternal interface this class implements. Though getSModel is not much better, at least in the context of SModelDescriptor it makes more sense.

Specified by:

getSModelInternal in class SModelDescriptorStub

getCurrentModelInternal

@Nullable
protected SModel getCurrentModelInternal()

Description copied from class: SModelBase

Likely, shall return SModelData eventually

Specified by:

getCurrentModelInternal in class SModelBase

Returns:

actual model data or null if not initialized yet

doUnload

protected void doUnload()

Description copied from class: SModelBase

Perform actual dispose of model data and SModelBase.setLoadingState(ModelLoadingState) changes loading state}. No loading state event is sent (responsibility of SModelBase.unload(). Subclasses shall override to clean instance fields and generally shall delegate to this implementation first to dispose model data.

Overrides:

doUnload in class SModelBase
