NameLookup provides name resolution within a Java project.
- * The name lookup facility uses the project's classpath to prioritize the
- * order in which package fragments are searched when resolving a name.
- *
- * Name lookup only returns a handle when the named element actually
- * exists in the model; otherwise null is returned.
- *
- *
There are two logical sets of methods within this interface. Methods
- * which start with find* are intended to be convenience methods for quickly
- * finding an element within another element; for instance, for finding a class within a
- * package. The other set of methods all begin with seek*. These methods
- * do comprehensive searches of the IJavaProject returning hits
- * in real time through an IJavaElementRequestor.
