java.lang.Object | +----java.rmi.server.ObjID
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.

Variable Index

o DGC_ID
well-known id for the distributed garbage collector
o REGISTRY_ID
well-known id for the registry

Constructor Index

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

Method Index

o equals(Object)
Two object identifiers are considered equal if they have the same contents.
o hashCode()
The hashcode is the object number.
o read(ObjectInput)
The read method constructs an object id whose contents is read from the specified input stream.
o toString()
Returns a string containing the object id representation.
o write(ObjectOutput)
Marshal object id to output stream.

Variables

o REGISTRY_ID public static final int REGISTRY_ID
well-known id for the registry

o DGC_ID public static final int DGC_ID
well-known id for the distributed garbage collector

Constructors

o ObjID public ObjID()
Generate unique object identifier.

o ObjID public ObjID(int num)
Generate a "well-known" object ID. An object ID generated via this constructor will not clash with any object IDs generated via the default constructor.

Parameters:
num - a unique well-known object number

Methods

o write public void write(ObjectOutput out) throws IOException
Marshal object id to output stream.

o read public static ObjID read(ObjectInput in) throws IOException
The read method constructs an object id whose contents is read from the specified input stream.

o hashCode public int hashCode()
The hashcode is the object number.

Overrides:
hashCode in class Object
o equals public boolean equals(Object obj)
Two object identifiers are considered equal if they have the same contents.

Overrides:
