Examples of net.sf.saxon.xqj.SaxonXQDataSource

net.sf.saxon.xqj.SaxonXQDataSource
Saxon implementation of the XQJ XQDataSource interface. The first action of a client application is to instantiate a SaxonXQDataSource. This is done directly: there is no factory class as with JAXP. An application that does not want compile-time references to the Saxon XQJ implementation can instantiate this class dynamically using the reflection API (class.newInstance()).
For full Javadoc descriptions of the public methods, see the XQJ specification.
