protected volatile boolean isInitializing

Constructor Detail

DerivedStateAwareResource

public DerivedStateAwareResource()

Method Detail

setDerivedStateComputer

public void setDerivedStateComputer(IDerivedStateComputer lateInitialization)

getContents

public org.eclipse.emf.common.util.EList<org.eclipse.emf.ecore.EObject> getContents()

As soon as an external client tries to access the content of the resource, the derived state will be added to the content of this resource.

Specified by:

getContents in interface org.eclipse.emf.ecore.resource.Resource

Overrides:

getContents in class org.eclipse.emf.ecore.resource.impl.ResourceImpl

updateInternalState

protected void updateInternalState(IParseResult oldParseResult,
                                   IParseResult newParseResult)

Overrides:

updateInternalState in class XtextResource

Parameters:

oldParseResult - the previous parse result that should be detached if necessary.

newParseResult - the current parse result that should be attached to the content of this resource

updateInternalState

protected void updateInternalState(IParseResult newParseResult)

Overridden to make sure that the cache is initialized during loading.

Overrides:

updateInternalState in class XtextResource

getURIFragmentRootSegment

protected java.lang.String getURIFragmentRootSegment(org.eclipse.emf.ecore.EObject eObject)

Overridden to make sure that we do not initialize a resource just to compute the root URI fragment for the parse result.

Overrides:

getURIFragmentRootSegment in class org.eclipse.emf.ecore.resource.impl.ResourceImpl

getEObjectForURIFragmentRootSegment

protected org.eclipse.emf.ecore.EObject getEObjectForURIFragmentRootSegment(java.lang.String uriFragmentRootSegment)

Not specialized because we want to obtain a fully working root instance when the resource is queried with the root fragment.

Overrides:

getEObjectForURIFragmentRootSegment in class org.eclipse.emf.ecore.resource.impl.ResourceImpl

discardDerivedState

public void discardDerivedState()

installDerivedState

public void installDerivedState(boolean preIndexingPhase)
