Examples of IErlElement

org.erlide.engine.model.root.IErlElement
Common protocol for all elements provided by the Erlang model. Erlang model elements are exposed to clients as handles to the actual underlying element. The Erlang model may hand out any number of handles for each element. Handles that refer to the same element are guaranteed to be equal, but not necessarily identical.
Methods annotated as "handle-only" do not require underlying elements to exist. Methods that require underlying elements to exist throw a ErlModelException when an underlying element is missing. ErlModelException.isDoesNotExist can be used to recognize this common special case.
