sun.tools.java.MethodSet

public class MethodSet
extends Object

The MethodSet structure is used to store methods for a class. It maintains the invariant that it never stores two methods with the same signature. MethodSets are able to lookup all methods with a given name and the unique method with a given signature (name, args). WARNING: The contents of this source file are not part of any supported API. Code that depends on them does so at its own risk: they are subject to change or removal without notice.

Methods

Modifier and Type	Method and Description
void	add(MemberDefinition method) Adds `method' to the MethodSet.
void	freeze() After freeze() is called, the MethodSet becomes (mostly) immutable.
boolean	isFrozen() Tells whether freeze() has been called on this MethodSet.
Iterator<MemberDefinition>	iterator() Returns an Iterator of all methods in the MethodSet
Iterator<MemberDefinition>	lookupName(Identifier name) Returns an Iterator of all methods contained in the MethodSet which have a given name.
MemberDefinition	lookupSig(Identifier name, Type type) If the MethodSet contains a method with the same signature then lookup() returns it.
void	replace(MemberDefinition method) Adds `method' to the MethodSet, replacing any previous definition with the same signature.
int	size() Returns the number of distinct methods stored in the MethodSet.
String	toString() Returns a (big) string representation of this MethodSet

MethodSet

public MethodSet()

Creates a brand new MethodSet

Method Detail

size

public int size()

Returns the number of distinct methods stored in the MethodSet.

add

public void add(MemberDefinition method)

Adds `method' to the MethodSet. No method of the same signature should be already defined.

replace

public void replace(MemberDefinition method)

Adds `method' to the MethodSet, replacing any previous definition with the same signature.

lookupSig

public MemberDefinition lookupSig(Identifier name,
                         Type type)

If the MethodSet contains a method with the same signature then lookup() returns it. Otherwise, this method returns null.

lookupName

public Iterator<MemberDefinition> lookupName(Identifier name)

Returns an Iterator of all methods contained in the MethodSet which have a given name.

iterator

public Iterator<MemberDefinition> iterator()

Returns an Iterator of all methods in the MethodSet

freeze

public void freeze()

After freeze() is called, the MethodSet becomes (mostly) immutable. Any calls to add() or addMeet() lead to CompilerErrors. Note that the entries themselves are still (unfortunately) open for mischievous and wanton modification.

isFrozen

public boolean isFrozen()

Tells whether freeze() has been called on this MethodSet.

toString

public String toString()

Returns a (big) string representation of this MethodSet

Overrides:

toString in class Object
