- the list of registered factory delegates
AbstractDelegatingFactory
protected AbstractDelegatingFactory(java.lang.Class[] supportedDelegateTypes)
- Parameters:
supportedDelegateTypes
- -- populates the list of classes used
by the isValidDelegate contract
addFactoryDelegate
public void addFactoryDelegate(org.eclipse.core.runtime.IAdaptable delegate)
- Description copied from interface:
IDelegatingFactory
- Adds delgate to the end of the list of factory delegates if the list
does not already contain it.
- Specified by:
addFactoryDelegate
in interface IDelegatingFactory
- Parameters:
delegate
- - See Also:
IDelegatingFactory.addFactoryDelegate(org.eclipse.core.runtime.IAdaptable)
removeFactoryDelegate
public boolean removeFactoryDelegate(org.eclipse.core.runtime.IAdaptable delegate)
- Specified by:
removeFactoryDelegate
in interface IDelegatingFactory
- Parameters:
delegate
-
- Returns:
- true if delegate was removed, false if delegate wasn't in
the list of delegates
- See Also:
IDelegatingFactory.removeFactoryDelegate(org.eclipse.core.runtime.IAdaptable)
getValidDelegateTypes
public java.util.List getValidDelegateTypes()
- Specified by:
getValidDelegateTypes
in interface IDelegatingFactory
- Returns:
- a list of Class objects that represent the interfaces
that may be passed to addFactoryDelegate. Implementor should
return at least one supported class.
- See Also:
IDelegatingFactory.getValidDelegateTypes()
isValidDelegate
public boolean isValidDelegate(org.eclipse.core.runtime.IAdaptable delegate)
- Description copied from interface:
IDelegatingFactory
- The return value of this method should conform to the following contract:
Let v = getValidDelegates. Then isValidDelegate should return true
only if the set of v contains a Class for which delegate.getAdapter(Class)
returns a non-null value.
- Specified by:
isValidDelegate
in interface IDelegatingFactory
- Parameters:
delegate
-
- Returns:
- true if delegate is supported, false otherwise.
