[castor-dev] what type of class members generate "has()" methods?

[Robert Ollila]

Hi,

Can anyone tell me under what circumstances the XML source generator creates
the "has<varname>()" method for a particular class member variable.  For
example, the sample invoice.xsd in the SourceGenerator directory results in
an Item class with members as follows:

    private boolean _inStock = false;

    /**
     * keeps track of state for field: _inStock
    **/
    private boolean _has_inStock;

    private java.lang.String _category;

    private java.lang.String _id;

    private int _quantity;

    /**
     * keeps track of state for field: _quantity
    **/
    private boolean _has_quantity;

    private java.math.BigDecimal _price;


Why do only members _inStock and _quantity have corresponding _has_XXX()
methods?  What are they used for anyways?

Any input would be appreciated,

Bob.
