Default constructor dynamic methods

Mapping of default constructors

This example shows how to map a default constructor. A method is generated for each dynamic class. This method sets the attributes with their default values, if they exist. The following example includes a function that adds an instance of a dynamic class Book, with the default attribute title equal to None.

Here is the schema:

<complexType name="book">
   <sequence>
     <element name="ident"/>
     <element name="title" minOccurs="0" default="None" />
   </sequence>
</complexType>

Here is the XOM representation:

Class Book extends IlrXmlObject
{
   String ident ;
   String title ;
   Book ();  // default constructor
}

And here is a function in IRL:

function void insertBook() {    

   // Add a new book, default value: ( ident = null, title="None" )
   insert ( new Book() );
}
