Constructor Detail- 
VMIDpublic 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 classjava.rmi.server.UIDare satisfied, and b) an address can be obtained for this host that is unique and constant for the lifetime of this object.

Method Detail- 
isUnique@Deprecated public static boolean isUnique() Deprecated.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
 
 - 
hashCodepublic int hashCode() Compute hash code for this VMID.- Overrides:
- hashCodein class- Object
- Returns:
- a hash code value for this object.

equalspublic boolean equals(Object obj) Compare this VMID to another, and return true if they are the same identifier.- Overrides:
- equalsin class- Object
- Parameters:
- obj- the reference object with which to compare.
- Returns:
- trueif this object is the same as the obj argument;- falseotherwise.
