Examples of org.eclipse.jdt.core.IJavaElement

org.eclipse.jdt.core.IJavaElement
Common protocol for all elements provided by the Java model. Java model elements are exposed to clients as handles to the actual underlying element. The Java 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 JavaModelException when an underlying element is missing. JavaModelException.isDoesNotExist can be used to recognize this common special case.
@noimplement This interface is not intended to be implemented by clients.
