public PDRange() 
{
        rangeArray = new COSArray();
        rangeArray.add( new COSFloat( 0.0f ) );
        rangeArray.add( new COSFloat( 1.0f ) );
        startingIndex = 0;
}

Constructor with an initial range of 0..1.

 public PDRange(COSArray range) 
{
        rangeArray = range;
}

Constructor assumes a starting index of 0.

Parameters:

range - The array that describes the range.

 public PDRange(COSArray range,
    int index) 
{
        rangeArray = range;
        startingIndex = index;
}

Constructor with an index into an array. Because some arrays specify multiple ranges ie [ 0,1, 0,2, 2,3 ] It is convenient for this class to take an index into an array. So if you want this range to represent 0,2 in the above example then you would say new PDRange( array, 1 ).

Parameters:

range - The array that describes the index

index - The range index into the array for the start of the range.

 public COSArray getCOSArray() 
{
        return rangeArray;
}

This will get the underlying array value.

 public COSBase getCOSObject() 
{
        return rangeArray;
}

Convert this standard java object to a COS object.

 public float getMax() 
{
        COSNumber max = (COSNumber)rangeArray.getObject( startingIndex*2+1 );
        return max.floatValue();
}

This will get the maximum value of the range.

 public float getMin() 
{
        COSNumber min = (COSNumber)rangeArray.getObject( startingIndex*2 );
        return min.floatValue();
}

This will get the minimum value of the range.

 public  void setMax(float max) 
{
        rangeArray.set( startingIndex*2+1, new COSFloat( max ) );
}

This will set the maximum value for the range.

 public  void setMin(float min) 
{
        rangeArray.set( startingIndex*2, new COSFloat( min ) );
}

This will set the minimum value for the range.
