Class Overview
A VMID is a identifier that is unique across all Java virtual
machines. VMIDs are used by the distributed garbage collector
to identify client VMs.

Public Constructors
public
VMID
()
Create a new VMID. Each new VMID returned from this constructor
is unique for all Java virtual machines under the following
conditions: a) the conditions for uniqueness for objects of
the class java.rmi.server.UID
are satisfied, and b) an
address can be obtained for this host that is unique and constant
for the lifetime of this object.
Public Methods
public
boolean
equals
(Object obj)
Compare this VMID to another, and return true if they are the
same identifier.
Parameters
obj
| the reference object with which to compare. |
Returns
true
if this object is the same as the obj
argument; false
otherwise.
public
int
hashCode
()
Compute hash code for this VMID.
Returns
- a hash code value for this object.
public
static
boolean
isUnique
()
This method is deprecated.
No replacement.
Return true if an accurate address can be determined for this
host. If false, reliable VMID cannot be generated from this host
Returns
- true if host address can be determined, false otherwise
public
String
toString
()
Return string representation of this VMID.
Returns
- a string representation of the object.
