boolean
Compare this VMID to another, and return true if they are the
same identifier.
int
Compute hash code for this VMID.
static boolean
Return string representation of this VMID.
Constructor Details
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 Details
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
hashCode
public int hashCode ()
Compute hash code for this VMID.
Overrides:
hashCode
in class Object
Returns:
a hash code value for this object.
See Also:
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
- the reference object with which to compare.
Returns:
true
if this object is the same as the obj
argument; false
otherwise.
See Also:
toString
Return string representation of this VMID.
Overrides:
toString
in class Object
Returns:
a string representation of the object.
