TransientBindingIterator

public class TransientBindingIterator extends BindingIteratorImpl
Class TransientBindingIterator implements the abstract methods defined by BindingIteratorImpl, to use with the TransientNamingContext implementation of the NamingContextImpl. The TransientBindingIterator implementation receives a hash table of InternalBindingValues, and uses an Enumeration to iterate over the contents of the hash table.

Fields Summary
private org.omg.PortableServer.POA
nsPOA
private int
currentSize
private Hashtable
theHashtable
private Enumeration
theEnumeration
Constructors Summary
public TransientBindingIterator(org.omg.CORBA.ORB orb, Hashtable aTable, org.omg.PortableServer.POA thePOA)
Constructs a new TransientBindingIterator object.

param
orb a org.omg.CORBA.ORB object.
param
aTable A hashtable containing InternalBindingValues which is the content of the TransientNamingContext.
param
java.lang.Exception a Java exception.
exception
Exception a Java exception thrown of the base class cannot initialize.

	super(orb);
	theHashtable = aTable;
	theEnumeration = this.theHashtable.elements();
	currentSize = this.theHashtable.size();
        this.nsPOA = thePOA;
Methods Summary
public final voidDestroy()
Destroys this BindingIterator by disconnecting from the ORB

exception
org.omg.CORBA.SystemException One of a fixed set of CORBA system exceptions.

	// Remove the object from the Active Object Map.
        try {
            byte[] objectId = nsPOA.servant_to_id( this );
            if( objectId != null ) {
                nsPOA.deactivate_object( objectId );
            }
        } 
        catch( Exception e ) {
            NamingUtils.errprint("BindingIterator.Destroy():caught exception:");
            NamingUtils.printException(e);
        }
public final booleanNextOne(org.omg.CosNaming.BindingHolder b)
Returns the next binding in the NamingContext. Uses the enumeration object to determine if there are more bindings and if so, returns the next binding from the InternalBindingValue.

param
b The Binding as an out parameter.
return
true if there were more bindings.

	// If there are more elements get the next element
	boolean hasMore = theEnumeration.hasMoreElements();
	if (hasMore) {
	    b.value =
		((InternalBindingValue)theEnumeration.nextElement()).theBinding;
	    currentSize--;
	} else {
	    // Return empty but marshalable binding
	    b.value = new Binding(new NameComponent[0],BindingType.nobject);
	}
	return hasMore;
public final intRemainingElements()
Returns the remaining number of elements in the iterator.

return
the remaining number of elements in the iterator.

	return currentSize;
