builder
Constructors Summary
public W3CDomHandler()
Default constructor. It is up to a JAXB provider to decide which DOM implementation to use or how that is configured.

        this.builder = null;
public W3CDomHandler(DocumentBuilder builder)
Constructor that allows applications to specify which DOM implementation to be used.

param
