All Implemented Interfaces:: Serializable

Most common way to construct:

VMID vmid = new VMID();

Based on 11 examples

public final class VMID
extends Object
implements Serializable

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.

Constructor Summary
`VMID()` Create a new VMID.

Method Summary
`boolean`	`equals(Object obj)` Compare this VMID to another, and return true if they are the same identifier.
`int`	`hashCode()` Compute hash code for this VMID.
`static boolean`	`isUnique()` Return true if an accurate address can be determined for this host.
`String`	`toString()` Return string representation of this VMID.

Constructor Detail

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.

Method Detail

equals

public boolean equals(Object obj)

Compare this VMID to another, and return true if they are the same identifier.

Overrides:: equals in class Object
Parameters:: obj

hashCode

public int hashCode()

Compute hash code for this VMID.

Overrides:: hashCode in class Object

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

toString

public String toString()

Return string representation of this VMID.

Overrides:: toString in class Object
