Method Detail

getResourceDescription

public IResourceDescription getResourceDescription(org.eclipse.emf.ecore.resource.Resource resource)

Specified by:

getResourceDescription in interface IResourceDescription.Manager

Returns:

a resource description for the given resource. The result represents the current state of the given resource.

createResourceDescription

protected IResourceDescription createResourceDescription(org.eclipse.emf.ecore.resource.Resource resource)

computeTypes

protected java.util.List<IEObjectDescription> computeTypes(org.eclipse.emf.ecore.resource.Resource resource)

createDelta

public IResourceDescription.Delta createDelta(IResourceDescription oldDescription,
                                     IResourceDescription newDescription)

Specified by:

createDelta in interface IResourceDescription.Manager

Returns:

a delta for both given descriptions.

isAffected

public boolean isAffected(IResourceDescription.Delta delta,
                 IResourceDescription candidate)
                   throws java.lang.IllegalArgumentException

Specified by:

isAffected in interface IResourceDescription.Manager

Returns:

whether the candidate is affected by the change in the delta.

Throws:

java.lang.IllegalArgumentException - if this manager is not responsible for the given candidate.

isAffected

public boolean isAffected(java.util.Collection<IResourceDescription.Delta> deltas,
                 IResourceDescription candidate,
                 IResourceDescriptions context)
                   throws java.lang.IllegalArgumentException

Description copied from interface: IResourceDescription.Manager

Batch operation to check whether a description is affected by any given delta in the given context. Implementations may perform any optimizations to return false whenever possible, e.g. check the deltas against the visible containers.

Specified by:

isAffected in interface IResourceDescription.Manager

Parameters:

deltas - List of deltas to check. May not be null.

candidate - The description to check. May not be null.

context - The current context of the batch operation. May not be null.

Returns:

whether the condidate is affected by any of the given changes.

Throws:

java.lang.IllegalArgumentException - if this manager is not responsible for the given candidate.
