Package com.sun.tools.javac.code

Class Scope.CompoundScope

java.lang.Object

com.sun.tools.javac.code.Scope

com.sun.tools.javac.code.Scope.CompoundScope

All Implemented Interfaces:

Scope.ScopeListener

Enclosing class:

Scope

public static class Scope.CompoundScope
extends Scope
implements Scope.ScopeListener

A class scope adds capabilities to keep track of changes in related class scopes - this allows client to realize whether a class scope has changed, either directly (because a new member has been added/removed to this scope) or indirectly (i.e. because a new member has been added/removed into a supertype scope)

getMark

public int getMark()

toString

public String toString()

Overrides:

toString in class Scope

getElements

public Iterable<Symbol> getElements(Filter<Symbol> sf)

Overrides:

getElements in class Scope

getElementsByName

public Iterable<Symbol> getElementsByName(Name name,
                                          Filter<Symbol> sf)

Overrides:

getElementsByName in class Scope

lookup

public Scope.Entry lookup(Name name,
                          Filter<Symbol> sf)

Overrides:

lookup in class Scope

dup

public Scope dup(Symbol newOwner)

Description copied from class: Scope

Construct a fresh scope within this scope, with new owner, which shares its table with the outer scope. Used in connection with method leave if scope access is stack-like in order to avoid allocation of fresh tables.

Overrides:

dup in class Scope

enter

public void enter(Symbol sym,
                  Scope s,
                  Scope origin,
                  boolean staticallyImported)

Description copied from class: Scope

Enter symbol sym in this scope, but mark that it comes from given scope `s' accessed through `origin'. The last two arguments are only used in import scopes.

Overrides:

enter in class Scope

remove

public void remove(Symbol sym)

Description copied from class: Scope

Remove symbol from this scope. Used when an inner class attribute tells us that the class isn't a package member.

Overrides:

remove in class Scope
