public final class ObjID
extends Object
implements Serializable

The class ObjID is used to identify remote objects uniquely in a VM
over time. Each identifier contains an object number and an address
space identifier that is unique with respect to a specific host. An
object identifier is assigned to a remote object when it is
exported.








DGC_ID
well-known id for the distributed garbage collector

REGISTRY_ID
well-known id for the registry






ObjID()
Generate unique object identifier.

ObjID(int)
Generate a "well-known" object ID.






equals(Object)
Two object identifiers are considered equal if they have the
same contents.

hashCode()
The hashcode is the object number.

read(ObjectInput)
The read method constructs an object id whose contents is read
from the specified input stream.

toString()
Returns a string containing the object id representation.

write(ObjectOutput)
Marshal object id to output stream.

public static final int REGISTRY_ID


well-known id for the registry


DGC_ID

public static final int DGC_ID

Parameters:
num - a unique well-known object number







write

public void write(ObjectOutput out) throws IOException


Marshal object id to output stream.



read
