Class DesignElementHandle

java.lang.Object
  extended by org.eclipse.birt.report.model.api.DesignElementHandle

public abstract class DesignElementHandle
extends java.lang.Object
implements org.eclipse.birt.report.model.elements.interfaces.IDesignElementModel

Base class for all report elements. Provides a high-level interface to the BIRT report model. This class provides generic services for all elements. Derived classes provide specialized methods for each element type.

Element handles are immutable. Once created, they always point to the same element. Handles also cannot point to a null element. An assertion will be raised if the derived classes are created with a null element.

For a complete description of the services available for any design element, see the class description for the DesignElementclass.
