Examples of org.pdf4j.saxon.query.DynamicQueryContext

org.pdf4j.saxon.query.DynamicQueryContext
This object represents a dynamic context for query execution. This class is used by the application writer to set up aspects of the dynamic context; it is not used operationally (or modified) by the XQuery processor itself, which copies all required information into its own internal representation.

            throws XPathException {
        if (query == null) {
