        fVector = v;        
        fLength = (v == null) ? 0 : v.size();
public StringListImpl(String[] array, int length)
Construct an XSObjectList implementation

param
array the data array
param
length the number of elements

        fArray = array;
        fLength = length;
Methods Summary
public booleancontains(java.lang.String item)
Checks if the GenericString item is a member of this list.

param
item GenericString whose presence in this list is to be tested.
return
True if this list contains the GenericString item.

        if (fVector != null)
            return fVector.contains(item);
        
        if (item == null) {
            for (int i = 0; i < fLength; i++) {
                if (fArray[i] == null)

            }
        }
        return false;
public intgetLength()
The number of Objects in the list. The range of valid child node indices is 0 to length-1 inclusive.

        return fLength;
public java.lang.Stringitem(int index)

        if (index < 0 || index >= fLength)
            return null;
