Constructor Detail

LazyEditableSModelBase

public LazyEditableSModelBase(@NotNull
                              SModelReference modelReference,
                              @NotNull
                              DataSource source)

Method Detail

getSModelInternal

public final 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

load

public final void load()

Description copied from interface: SModel

When owning a read action lock, this method will fully load the model from the storage. Does nothing if already loaded. The load() method is called automatically on a not-loaded model whenever elements from it are being resolved. Problems can be retrieved later by the SModel.getProblems() method.

Specified by:

load in interface SModel

Overrides:

load in class SModelBase

getCurrentModelInternal

protected final 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

loadSModel

protected abstract ModelLoadResult loadSModel(ModelLoadingState state)

loads model from the source, w/o changing state of SModelDescriptor

reloadContents

protected void reloadContents()

Specified by:

reloadContents in class EditableSModelBase
