All Implemented Interfaces:

public class RegionBasedTypeHierarchy
extends TypeHierarchy

Field Summary

protected IRegion

region The region of types for which to build the hierarchy

Constructor Summary

RegionBasedTypeHierarchy(IRegion region, ICompilationUnit[] workingCopies, IType type, boolean computeSubtypes)
Creates a TypeHierarchy on the types in the specified region, considering first the given working copies, using the projects in the given region for a name lookup context.

Method Summary

protected void	compute() Compute this type hierarchy.
protected void	initializeRegions() Initializes the file, package and project regions
protected boolean	isAffectedByOpenable(IJavaElementDelta delta, IJavaElement element, int eventType) Returns true if the given type delta (a compilation unit delta or a class file delta) could affect this type hierarchy.
IJavaProject	javaProject() Returns the java project this hierarchy was created in.
void	pruneDeadBranches()
protected void	removeType(IType type) Removes all the subtypes of the given type from the type hierarchy, removes its superclass entry and removes the references from its super types.

Field Detail

region

protected IRegion region

The region of types for which to build the hierarchy

Constructor Detail

RegionBasedTypeHierarchy

public RegionBasedTypeHierarchy(IRegion region,
                                ICompilationUnit[] workingCopies,
                                IType type,
                                boolean computeSubtypes)

Creates a TypeHierarchy on the types in the specified region, considering first the given working copies, using the projects in the given region for a name lookup context. If a specific type is also specified, the type hierarchy is pruned to only contain the branch including the specified type.

Method Detail

initializeRegions

protected void initializeRegions()

Description copied from class: TypeHierarchy

Initializes the file, package and project regions

Overrides:

initializeRegions in class TypeHierarchy

compute

protected void compute()
                throws JavaModelException,
                       CoreException

Compute this type hierarchy.

Overrides:

compute in class TypeHierarchy

Throws:

JavaModelException

CoreException

isAffectedByOpenable

protected boolean isAffectedByOpenable(IJavaElementDelta delta,
                                       IJavaElement element,
                                       int eventType)

Description copied from class: TypeHierarchy

Returns true if the given type delta (a compilation unit delta or a class file delta) could affect this type hierarchy.

Overrides:

isAffectedByOpenable in class TypeHierarchy

eventType - TODO

javaProject

public IJavaProject javaProject()

Returns the java project this hierarchy was created in.

Overrides:

javaProject in class TypeHierarchy

pruneDeadBranches

public void pruneDeadBranches()

removeType

protected void removeType(IType type)

Removes all the subtypes of the given type from the type hierarchy, removes its superclass entry and removes the references from its super types.
