Class DocumentProvider

  • All Implemented Interfaces:
    Provider

    class DocumentProvider
    extends java.lang.Object
    implements Provider
    The DocumentProvider object is used to provide event reader implementations for DOM. Wrapping the mechanics of the DOM framework within a Provider ensures that it can be plugged in without any dependencies. This allows other parsers to be swapped in should there be such a requirement.

        public EventReader provide​(java.io.InputStream source)
                            throws java.lang.Exception
        This provides an EventReader that will read from the specified input stream. When reading from an input stream the character encoding should be taken from the XML prolog or it should default to the UTF-8 character encoding.
        Specified by:
        provide in interface Provider
        Parameters:
        source - this is the stream to read the document with
        Returns:
        this is used to return the event reader implementation
        Throws:
        java.lang.Exception
