org.eclipse.ui.internal .ObjectContributorManager

All known Subclasses:   org.eclipse.ui.internal.decorators .LightweightDecoratorManager,  org.eclipse.ui.internal .ObjectActionContributorManager,  org.eclipse.ui.internal.dialogs .PropertyPageContributorManager,
ObjectContributorManager
abstract public class ObjectContributorManager implements IExtensionChangeHandler(Code)
This class is a default implementation of IObjectContributorManager. It provides fast merging of contributions with the following semantics:

All of the matching contributors will be invoked per property lookup
The search order from a class with the definition
class X extends Y implements A, B
is as follows:
the target's class: X
X's superclasses in order to Object
a depth-first traversal of the target class's interaces in the order returned by getInterfaces() (in the example, A and its superinterfaces then B and its superinterfaces)

See Also:   IObjectContributor

Constructor Detail
ObjectContributorManager
public ObjectContributorManager()(Code)
Constructs a new contributor manager.

Method Detail
addContributorsFor
protected List addContributorsFor(Class objectClass)(Code)
Return the list of contributors for the supplied class.

canHandleExtensionTracking
protected boolean canHandleExtensionTracking()(Code)
Return whether or not the receiver handles extension tracking. Default is true. Subclasses may override. boolean true if it should be registeredas an extension handler.

dispose
public void dispose()(Code)
Remove listeners and dispose of this manager.
since:
   3.1

flushLookup
public void flushLookup()(Code)
Flushes the cache of contributor search paths. This is generally required whenever a contributor is added or removed.
It is likely easier to just toss the whole cache rather than trying to be smart and remove only those entries affected.

since:
   3.0

getContributors

  elements - a list of model elements (Object) the list of interested contributors (IObjectContributor)

getObjectContributors
protected List getObjectContributors(Class objectClass)(Code)
Returns the contributions for the given class. This considers contributors on any super classes and interfaces.
Parameters:
  objectClass - the class to search for contributions. the contributions for the given class. This considerscontributors on any super classes and interfaces.
since:
   3.1

getResourceContributors
protected List getResourceContributors(Class resourceClass)(Code)
Returns the contributions for the given IResourceclass. This considers contributors on any super classes and interfaces. This will only return contributions that are adaptable.
Parameters:
  resourceClass - the class to search for contributions. the contributions for the given class. This considersadaptable contributors on any super classes and interfaces.
since:
   3.1

hasContributorsFor
