Constructor Detail

Symbol.MethodSymbol

public Symbol.MethodSymbol(long flags,
                           Name name,
                           Type type,
                           Symbol owner)

Construct a method symbol, given its flags, name, type and owner.

Method Detail

clone

public Symbol.MethodSymbol clone(Symbol newOwner)

Clone this symbol with new owner.

Overrides:

clone in class Symbol

toString

public java.lang.String toString()

The Java source which this symbol represents.

Overrides:

toString in class Symbol

implemented

public Symbol implemented(Symbol.TypeSymbol c,
                          Types types)

find a symbol that this (proxy method) symbol implements.

Parameters:

c - The class whose members are searched for implementations

binaryOverrides

public boolean binaryOverrides(Symbol _other,
                               Symbol.TypeSymbol origin,
                               Types types)

Will the erasure of this method be considered by the VM to override the erasure of the other when seen from class `origin'?

binaryImplementation

public Symbol.MethodSymbol binaryImplementation(Symbol.ClassSymbol origin,
                                                Types types)

The implementation of this (abstract) symbol in class origin, from the VM's point of view, null if method does not have an implementation in class.

Parameters:

origin - The class of which the implementation is a member.

overrides

public boolean overrides(Symbol _other,
                         Symbol.TypeSymbol origin,
                         Types types,
                         boolean checkResult)

Does this symbol override `other' symbol, when both are seen as members of class `origin'? It is assumed that _other is a member of origin. It is assumed that both symbols have the same name. The static modifier is ignored for this test. See JLS 8.4.6.1 (without transitivity) and 8.4.6.4

Overrides:

overrides in class Symbol

isOverridableIn

private boolean isOverridableIn(Symbol.TypeSymbol origin)

implementation
