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
trueif this object is the same as the obj argument;falseotherwise.
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.
