All Implemented Interfaces:

TypeContext

public class LibraryContext
extends DelegatingContext

A context that can access top-level classes from a Library.

Constructor Summary

LibraryContext(Library lib)
Create a LibraryContext that delegates to the BaseContext.

LibraryContext(TypeContext next, Library lib)
Create a LibraryContext that delegates to the given context (typically another LibraryContext).

Method Summary

protected TypeContext	duplicate(TypeContext next) Create a copy of this context with the given context enclosing it.
java.lang.ClassLoader	getClassLoader() Return the class loader for the current scope.
DJClass	getTopLevelClass(java.lang.String name, TypeSystem ts) Return the top-level class with the given name, or null if it does not exist.
VariableType	getTypeVariable(java.lang.String name, TypeSystem ts) Return the type variable with the given name, or null if it does not exist.
boolean	memberClassExists(java.lang.String name, TypeSystem ts) Test whether name is an in-scope member class
boolean	topLevelClassExists(java.lang.String name, TypeSystem ts) Test whether name is an in-scope top-level class
ClassType	typeContainingMemberClass(java.lang.String name, TypeSystem ts) Return the most inner type containing a class with the given name, or null if there is no such type.
boolean	typeExists(java.lang.String name, TypeSystem ts) Test whether name is an in-scope top-level class, member class, or type variable
boolean	typeVariableExists(java.lang.String name, TypeSystem ts) Test whether name is an in-scope type variable.
