InterfaceMethodSignature (Jikes RVM API)

java.lang.Object
- org.jikesrvm.classloader.InterfaceMethodSignature

```
public final class InterfaceMethodSignature
extends Object
```
An interface method signature is a pair of atoms: interfaceMethodName + interfaceMethodDescriptor.

```
private static final ImmutableEntryHashSetRVM<InterfaceMethodSignature> dictionary
```
    Used to canonicalize InterfaceMethodSignatures
  - nextId
```
private static int nextId
```
    Used to assign ids. Don't use id 0 to allow clients to use id 0 as a 'null'.
  - name
```
private final Atom name
```
    Name of the interface method
  - descriptor
```
private final Atom descriptor
```
    Descriptor of the interface method
  - id
```
private final int id
```
    Id of this interface method signature (not used in hashCode or equals).

private InterfaceMethodSignature(Atom name,
                                 Atom descriptor,
                                 int id)
```
- Method Detail
  - findOrCreate
```
public static InterfaceMethodSignature findOrCreate(MemberReference ref)
```
    Find or create an interface method signature for the given method reference.
    
    Parameters:
    
    ref - A reference to a supposed interface method
    
    Returns:
    
    the interface method signature
  - getName
```
public Atom getName()
```
    Returns:
    
    name of the interface method
  - getDescriptor
```
public Atom getDescriptor()
```
    Returns:
    
    descriptor of hte interface method
  - getId
```
public int getId()
```
    Returns:
    
    the id of thie interface method signature.
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
  - equals
```
public boolean equals(Object other)
```
    Overrides:
    
    equals in class Object
  - getIMTOffset
```
public Offset getIMTOffset()
```
    If using embedded IMTs, Get offset of interface method slot in TIB. If using indirect IMTs, Get offset of interface method slot in IMT. Note that all methods with same name & descriptor map to the same slot.
    TODO!! replace this stupid offset assignment algorithm with something more reasonable.
    
    Returns:
    
    offset in TIB/IMT
