Method Detail

visit

public final boolean visit(org.eclipse.core.resources.IResourceChangeEvent event)
                    throws org.eclipse.core.runtime.CoreException

Visits supplied resource change event.

Invokes resolveEvent(event) and returns the computed result.

Returns:

true if the resource change events's delta or resource should be visited, false if they should be skipped

Throws:

org.eclipse.core.runtime.CoreException - if the visit fails for some reason

visit

public final boolean visit(org.eclipse.core.resources.IResourceDelta delta)
                    throws org.eclipse.core.runtime.CoreException

Visits supplied resource delta.

Invokes resolveDelta(delta) and returns the computed result.

Specified by:

visit in interface org.eclipse.core.resources.IResourceDeltaVisitor

Returns:

true if the resource delta's children should be visited, false if they should be skipped

Throws:

org.eclipse.core.runtime.CoreException - if the visit fails for some reason

visit

public final boolean visit(org.eclipse.core.resources.IResource resource)
                    throws org.eclipse.core.runtime.CoreException

Visits supplied resource.

Invokes resolveResource(resource) and returns the computed result.

Specified by:

visit in interface org.eclipse.core.resources.IResourceVisitor

Returns:

true if the resource's members should be visited, false if they should be skipped

Throws:

org.eclipse.core.runtime.CoreException - if the probe fails for some reason

resolveEvent

protected abstract boolean resolveEvent(org.eclipse.core.resources.IResourceChangeEvent event)
                                 throws org.eclipse.core.runtime.CoreException

Throws:

org.eclipse.core.runtime.CoreException

resolveDelta

protected abstract boolean resolveDelta(org.eclipse.core.resources.IResourceDelta delta)
                                 throws org.eclipse.core.runtime.CoreException

Throws:

org.eclipse.core.runtime.CoreException

resolveResource

protected abstract boolean resolveResource(org.eclipse.core.resources.IResource resource)
                                    throws org.eclipse.core.runtime.CoreException

Throws:

org.eclipse.core.runtime.CoreException

resolve

public final void resolve(@Nullable
                          org.eclipse.core.resources.IResourceChangeEvent event)

Resolves supplied resource resource change event.

Visits resource event or returns silently if event is null.

This method always invokes preResolve() before resolving but invokes postResolve() only after successful resolving (post hook is not invoked in case of an exception).

Throws:

RuntimeCoreException - if the visit fails for some reason

resolve

public final void resolve(@Nullable
                          org.eclipse.core.resources.IResourceDelta delta,
                          @Nullable
                          org.eclipse.core.resources.IResource resource)

Resolves supplied resource delta or resource.

Visits first non null parameter or returns silently if both are null.

This method always invokes preResolve() before resolving but invokes postResolve() only after successful resolving (post hook is not invoked in case of an exception).

Throws:

RuntimeCoreException - if the visit fails for some reason
