same identifier.

hashCode()
Compute hash code for this VMID.

isUnique()
Return true if an accurate address can be determined for this
host.

toString()
Return string representation of this VMID.







VMID

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.
The static method isUnique can be invoked to determine
if an accurate address can be obtained for this host.







isUnique

public static boolean isUnique()


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



hashCode

public int hashCode()

Overrides:
hashCode in class Object



equals

public boolean equals(Object obj)
