Method Detail

getAllResourceDescriptions

public Iterable<IResourceDescription> getAllResourceDescriptions()

Specified by:

getAllResourceDescriptions in interface IResourceDescriptions

setRegistry

public void setRegistry(IResourceServiceProvider.Registry registry)

getResourceSet

public org.eclipse.emf.ecore.resource.ResourceSet getResourceSet()

getSelectables

protected Iterable<? extends ISelectable> getSelectables()

Specified by:

getSelectables in class AbstractCompoundSelectable

isEmpty

public boolean isEmpty()

Description copied from interface: ISelectable

Clients may want to check the selectable to skip its processing in case it is empty. Implementations should be fast and not require expensive precalculation. Selectable may return false if it is too expensive to compute the actual result.

Specified by:

isEmpty in interface ISelectable

Overrides:

isEmpty in class AbstractCompoundSelectable

Returns:

true if the selectable does not provide any descriptions.

hasDescription

protected boolean hasDescription(org.eclipse.emf.common.util.URI uri)

Since:

2.1

setContext

public void setContext(org.eclipse.emf.common.notify.Notifier ctx)

Specified by:

setContext in interface IResourceDescriptions.IContextAware

toString

public String toString()

Overrides:

toString in class Object

getResourceDescription

public IResourceDescription getResourceDescription(org.eclipse.emf.common.util.URI uri)

Description copied from interface: IResourceDescriptions

Returns the resource descriptions for the given URI.

Specified by:

getResourceDescription in interface IResourceDescriptions
