| org.geotools.catalog.ResolveDelta
All known Subclasses: org.geotools.catalog.defaults.DefaultResolveDelta,
| ResolveDelta | | public interface ResolveDelta (Code) | | Constants used to communicate Catalog Deltas.
For those familiar with IResourceChangeEvent and IResourceDelta from eclipse development there is
one important addition. The constant REPLACE indicates a reaname, or substiution, you
will need to replace any references you have to the oldObject with the newObject.
For "bit mask" style interation please use: EnumSet.of(Kind.ADDED, Kind.REPLACED)

| Method Summary | |
| void | accept(ResolveDeltaVisitor visitor)
Accepts the given visitor. | | List | getChildren()
Resource deltas for all added, removed, changed, or replaced. | | List | getChildren(Set kindMask)
Finds and returns the delta information for a given resource. | | Kind | getKind()
Returns the kind of this delta.
Normally, one of ADDED, REMOVED, CHANGED or
REPLACED.
This set is still open, during shutdown we may throw a few more kinds around. | | Resolve | getNewResolve()
For replacement (REPLACE), this handle describes the resource in the "after"
state. | | Resolve | getResolve()
Returns a handle for the affected handle.
For additions (ADDED), this handle describes the newly-added resolve; i.e.,
the one in the "after" state.
For changes (CHANGED), this handle also describes the resource in the
"after" state.
For removals (REMOVED), this handle describes the resource in the "before"
state. |
| NO_CHILDREN | | final static List NO_CHILDREN(Code) | | List indicating no children are present
|
| accept | | void accept(ResolveDeltaVisitor visitor) throws IOException(Code) | | Accepts the given visitor.
The only kinds of resource delta that our visited are ADDED, REMOVED, CHANGED and REPLACED.
This is a convenience method, equivalent to accepts( visitor, IService.NONE )
Parameters:
visitor -
throws:
CoreException - |
| getChildren | | List getChildren()(Code) | | Resource deltas for all added, removed, changed, or replaced.
This is a short cut for:
finally List list = new ArrayList();
accept( IServiceDeltaVisitor() {
public boolean visit(IResolveDelta delta) {
switch (delta.getKind()) {
case IDelta.ADDED :
case IDelta.REMOVED :
case IDelta.CHANGED :
case IDelta.REPLACED :
list.add( delta );
default: // ignore
}
return true;
}
});
return list.toArray();
A list of type ResolveDelta. |
| getChildren | | List getChildren(Set kindMask)(Code) | | Finds and returns the delta information for a given resource.
Parameters:
kindMask - Set of IDelta.Kind List of IGeoResourceDelta |
| getKind | | Kind getKind()(Code) | | Returns the kind of this delta.
Normally, one of ADDED, REMOVED, CHANGED or
REPLACED.
This set is still open, during shutdown we may throw a few more kinds around. Eclipse makes
use of PHANTOM, and NON_PHANTOM not sure we care
the kind of this resource delta

| getNewResolve | | Resolve getNewResolve()(Code) | | For replacement (REPLACE), this handle describes the resource in the "after"
state. The old handle can be determined with getResolve().
The new resolve replacing the affected handle. |
| getResolve | | Resolve getResolve()(Code) | | Returns a handle for the affected handle.
For additions (ADDED), this handle describes the newly-added resolve; i.e.,
the one in the "after" state.
For changes (CHANGED), this handle also describes the resource in the
"after" state.
For removals (REMOVED), this handle describes the resource in the "before"
state. Even though this handle not normally exist in the current workspace, the type of
resource that was removed can be determined from the handle.
For removals (REPLACE), this handle describes the resource in the "before"
state. The new handle can be determined with getNewResolve().
