Method Detail

dispose

public void dispose()

Description copied from class: BaseContent

Disposes of this content. It is the method's responsibility to call dispose on all child elements. Important: do NOT call dispose on the children observable collection as it will be invoked when the observable tree viewer processes the list diffs. This implementation should only release those resources (matchers / engines / etc) which are directly bound to this content.

Specified by:

dispose in class BaseContent<ParentType>

updateHasChildren

public void updateHasChildren()

Call this method if the element is already present in the tree viewer, but it is not expanded yet and the children list has changed. In this case, even if the children are updated properly, the tree viewer will not show that the element has children. Calling this method only has effect if the element is not expanded yet (because in these cases the observable list propagates the updates properly).

getChildrenIterator

public abstract java.util.Iterator<ChildType> getChildrenIterator()

Returns an iterator on the child elements.

Returns:

the iterator on the child elements

getChildren

public abstract org.eclipse.core.databinding.observable.list.IObservableList getChildren()

Returns the IObservableList of child elements.

Returns:

the observable list of child elements
