Tracing of Abstract array:

inline int isZero( const Object& o )

{

    return o == NOOBJECT;

}

 

int AbstractArray::isEqual( const Object& obj ) const

{

    PRECONDITION( isA() == obj.isA() );

    AbstractArray& test = (AbstractArray&)obj;

    if( lowerBound() != test.lowerBound() ||

        upperBound() != test.upperBound()

      )

        return 0;

 

    ContainerIterator& iter1 = initIterator();

    ContainerIterator& iter2 = test.initIterator();

    while( iter1 && iter2 )

        if( iter1.current() != iter2.current() )

            {

            delete &iter1;

            delete &iter2;

            return 0;

            }

        else

            {

            iter1++;

            iter2++;

            }

 

    delete &iter1;

    delete &iter2;

    return 1;

}

 

void AbstractArray::printContentsOn( ostream& outputStream ) const

{

    ContainerIterator& printIterator = initIterator();

    printHeader( outputStream );

    while( printIterator != 0 )

        {

        Object& arrayObject = printIterator++;

        if( arrayObject != NOOBJECT )

            {

            arrayObject.printOn( outputStream );

            if( printIterator != 0 )

                printSeparator( outputStream );

            else

                break;

            }

        }

    printTrailer( outputStream );

    delete &printIterator;

}
