+----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.
-
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.
REGISTRY_ID
public static final int REGISTRY_ID
- well-known id for the registry
DGC_ID
public static final int DGC_ID
- well-known id for the distributed garbage collector
ObjID
public ObjID()
- Generate unique object identifier.
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
write
public void write(ObjectOutput out) throws IOException
- Marshal object id to output stream.
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.
hashCode
public int hashCode()
- The hashcode is the object number.
- Overrides:
- hashCode in class Object
equals
public boolean equals(Object obj)
- Two object identifiers are considered equal if they have the
same contents.
- Overrides:
- equals in class Object
toString
public String toString()
- Returns a string containing the object id representation. The
address space identifier is included in the string
representation only if the object id is from a non-local
address space.
- Overrides:
