Interface IBaseLabelProvider

    • Method Detail

      • addListener

        void addListener​(ILabelProviderListener listener)
        Adds a listener to this label provider. Has no effect if an identical listener is already registered.

        Label provider listeners are informed about state changes that affect the rendering of the viewer that uses this label provider.

        Parameters:
        listener - a label provider listener
      • dispose

        void dispose()
        Disposes of this label provider. When a label provider is attached to a viewer, the viewer will automatically call this method when the viewer is being closed. When label providers are used outside of the context of a viewer, it is the client's responsibility to ensure that this method is called when the provider is no longer needed.
      • isLabelProperty

        boolean isLabelProperty​(Object element,
                                String property)
        Returns whether the label would be affected by a change to the given property of the given element. This can be used to optimize a non-structural viewer update. If the property mentioned in the update does not affect the label, then the viewer need not update the label.
        Parameters:
        element - the element
        property - the property
        Returns:
        true if the label would be affected, and false if it would be unaffected
      • removeListener

        void removeListener​(ILabelProviderListener listener)
        Removes a listener to this label provider. Has no effect if an identical listener is not registered.
        Parameters:
        listener - a label provider listener
