sun.reflect.generics.scope
abstract public class: AbstractScope [javadoc | source]

java.lang.Object
   sun.reflect.generics.scope.AbstractScope

All Implemented Interfaces:
    Scope

Direct Known Subclasses:
    MethodScope, ConstructorScope, ClassScope

Abstract superclass for lazy scope objects, used when building factories for generic information repositories. The type parameter D represents the type of reflective object whose scope this class is representing.

To subclass this, all one needs to do is implement computeEnclosingScope and the subclass' constructor.

Constructor:
protected AbstractScope(D decl) { recvr = decl; } Constructor. Takes a reflective object whose scope the newly constructed instance will represent. Parameters: D - - A generic declaration whose scope the newly constructed instance will represent

Method from sun.reflect.generics.scope.AbstractScope Summary:
computeEnclosingScope,   getEnclosingScope,   getRecvr,   lookup

Methods from java.lang.Object:
clone,   equals,   finalize,   getClass,   hashCode,   notify,   notifyAll,   toString,   wait,   wait,   wait

Method from sun.reflect.generics.scope.AbstractScope Detail:
abstract protected Scope computeEnclosingScope() This method must be implemented by any concrete subclass. It must return the enclosing scope of this scope. If this scope is a top-level scope, an instance of DummyScope must be returned.
protected Scope getEnclosingScope() { if (enclosingScope == null) {enclosingScope = computeEnclosingScope();} return enclosingScope; } Accessor for the enclosing scope, which is computed lazily and cached.
protected D getRecvr() { return recvr; } Accessor for the receiver - the object whose scope this Scope object represents.
public TypeVariable<?> lookup(String name) { TypeVariable[] tas = getRecvr().getTypeParameters(); for (TypeVariable/*< ? >*/ tv : tas) { if (tv.getName().equals(name)) {return tv;} } return getEnclosingScope().lookup(name); } Lookup a type variable in the scope, using its name. Returns null if no type variable with this name is declared in this scope or any of its surrounding scopes.
