Examples of com.ctc.wstx.io.WstxInputSource

com.ctc.wstx.io.WstxInputSource
Interface that defines API actual parsers (stream readers) can use to read input from various input sources. Needed to abstract out details of getting input from primary input files, secondary (potentially cached) referenced documents, and from parsed entities, as well as for allowing hierarchic location information for error reporting.

        /* Let's mark the current input source as the scope, so we can both
         * make sure it ends in this input context (DTD subset), and that
         * embedded single/double quotes in potentially expanded entities do
         * not end the value definition (as per XML 1.0/3, 4.4.5)
