Stub

public Stub()

Method Detail

hashCode

public int hashCode()

Returns a hash code value for the object which is the same for all stubs that represent the same remote object.

Overrides:

[hashCode](../../../org/omg/CORBA/portable/ObjectImpl.html#hashCode%28%29) in class [ObjectImpl](../../../org/omg/CORBA/portable/ObjectImpl.html "class in org.omg.CORBA.portable")

Returns:

the hash code value.

See Also:

Object.equals(java.lang.Object), Hashtable

equals

public boolean equals(Object obj)

Compares two stubs for equality. Returns true when used to compare stubs that represent the same remote object, and false otherwise.

Overrides:

[equals](../../../org/omg/CORBA/portable/ObjectImpl.html#equals%28java.lang.Object%29) in class [ObjectImpl](../../../org/omg/CORBA/portable/ObjectImpl.html "class in org.omg.CORBA.portable")

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:

Object.hashCode(), Hashtable

toString

public String toString()

Returns a string representation of this stub. Returns the same string for all stubs that represent the same remote object.

Overrides:

[toString](../../../org/omg/CORBA/portable/ObjectImpl.html#toString%28%29) in class [ObjectImpl](../../../org/omg/CORBA/portable/ObjectImpl.html "class in org.omg.CORBA.portable")

Returns:

a string representation of this stub.

connect

public void connect(ORB orb) throws RemoteException

Connects this stub to an ORB. Required after the stub is deserialized but not after it is demarshalled by an ORB stream. If an unconnected stub is passed to an ORB stream for marshalling, it is implicitly connected to that ORB. Application code should not call this method directly, but should call the portable wrapper method [PortableRemoteObject.connect(java.rmi.Remote, java.rmi.Remote)](../../../javax/rmi/PortableRemoteObject.html#connect%28java.rmi.Remote, java.rmi.Remote%29).

Parameters:

orb - the ORB to connect to.

Throws:

[RemoteException](../../../java/rmi/RemoteException.html "class in java.rmi") - if the stub is already connected to a different ORB, or if the stub does not represent an exported remote or local object.
