   public static final int NPM_HASH_DEFAULT

Default hash code for new NPM objects.

· PortType

Summary  |  Top
   static final int PortType

Define "types" for each kind of NPM object. these types are not used outside of the package, users can use the Class of each object to do their own checks. I would have like to use static Class references here, but initialization proved to be a sadistic pain in the butt. Perhaps if I went native...

· PortSetType

Summary  |  Top
   static final int PortSetType

· ThreadType

Summary  |  Top
   static final int ThreadType

· SpaceType

Summary  |  Top
   static final int SpaceType

   public NPMObject() 


· s_init

Summary  |  Top
   void s_init(int hashCode) 

· destroy

Summary  |  Top
   public void destroy() 

Destroy this object. At this level that simply means setting the active_ flag to false.

· hashCode

Summary  |  Top
   public int hashCode() 

Return the hashCode associated with this object. Hashcodes default to the standard Java hashcode, unless overridden at object creation time. Hashcodes are read-only once the object is created.

the integer hashcode associated with this object.
hashCode in class Object

· s_hashCode

Summary  |  Top
   int s_hashCode() 

Return the hashCode associated with this object. This is the package-level interface to this object. No locking is required as this is a read-only value.

· move

Summary  |  Top
   public void move(Reference srcPool, 
                    Reference destPool) 

Move this object from one MemPool into target MemPool. XXX: Not implmented, probably not necessary.

· s_isActive

Summary  |  Top
   boolean s_isActive() 

Determine if the current object is alive or not.

true if this is active, false if not.

· s_assertActive

Summary  |  Top
   void s_assertActive()  throws InvalidObjectException

Throw NPMInvalidObject if this object has been destroyed.

· toString

Summary  |  Top
   public abstract String toString() 
toString in class Object

· finalize

Summary  |  Top
   public void finalize() 

Finalize this object. Simply calls destroy.

· clone

Summary  |  Top
   public final Object clone()  throws CloneNotSupportedException, OutOfMemoryError

No NPM object supports clone().

See Also: Object.clone

· typeName

Summary  |  Top
   static String typeName() 

· s_type

Summary  |  Top
   abstract int s_type() 

Return the type of this NPM object. The Class of the object is used to represent its type.

The type of this object (its class.)

· debug_label
