## Class ToUnknownStream

- java.lang.Object
- - org.apache.xml.serializer.SerializerBase
  - - org.apache.xml.serializer.ToUnknownStream

- All Implemented Interfaces:
    DOMSerializer, ExtendedContentHandler, ExtendedLexicalHandler, SerializationHandler, Serializer, org.xml.sax.ContentHandler, org.xml.sax.DTDHandler, org.xml.sax.ErrorHandler, org.xml.sax.ext.DeclHandler, org.xml.sax.ext.LexicalHandler

      public final class ToUnknownStream
      extends SerializerBase

  This class wraps another SerializationHandler. The wrapped object will either handler XML or HTML, which is not known until a little later when the first XML tag is seen. If the first tag is
  then the wrapped object is an HTML handler, otherwise it is an XML handler. This class effectively caches the first few calls to it then passes them on to the wrapped handler (once it exists). After that subsequent calls a simply passed directly to the wrapped handler. The user of this class doesn't know if the output is ultimatley XML or HTML. This class is not a public API, it is public because it is used within Xalan.
  Usage:
    **For internal use only**

                                     throws org.xml.sax.SAXException

      Description copied from interface: `ExtendedContentHandler`
      This method is used to notify that a prefix maping is to start, which can be for the current element, or for the one to come.
      Parameters:
        `prefix` - the prefix that maps to the given URI
        `uri` - the namespace URI of the given prefix
        `shouldFlush` - if true this call is like the SAX startPrefixMapping(prefix,uri) call and the mapping applies to the element to come. If false the mapping applies to the current element.
      Returns:
        boolean false if the prefix mapping was already in effect (in other words we are just re-declaring), true if this is a new, never before seen mapping for the element.
      Throws:
        `org.xml.sax.SAXException`

        `setDocumentLocator` in interface `org.xml.sax.ContentHandler`
      Overrides:
        `setDocumentLocator` in class `SerializerBase`
      Parameters:
        `locator` - An object that can return the location of any SAX document event. Receive an object for locating the origin of SAX document events.

        SAX parsers are strongly encouraged (though not absolutely required) to supply a locator: if it does so, it must supply the locator to the application by invoking this method before invoking any of the other methods in the DocumentHandler interface.

        The locator allows the application to determine the end position of any document-related event, even if the parser is not reporting an error. Typically, the application will use this information for reporting its own errors (such as character content that does not match an application's business rules). The information returned by the locator is probably not sufficient for use with a search engine.

        Note that the locator will return correct information only during the invocation of the events in this interface. The application should not attempt to use it at any other time.

    - #### flushPending

          public void flushPending()
                            throws org.xml.sax.SAXException

      Description copied from interface: `SerializationHandler`
      A SerializationHandler accepts SAX-like events, so it can accumulate attributes or namespace nodes after a startElement().

      If the SerializationHandler has a Writer or OutputStream, a call to this method will flush such accumulated events as a closed start tag for an element.

      If the SerializationHandler wraps a ContentHandler, a call to this method will flush such accumulated events as a SAX (not SAX-like) calls to startPrefixMapping() and startElement().

      If one calls endDocument() then one need not call this method since a call to endDocument() will do what this method does. However, in some circumstances, such as with document fragments, endDocument() is not called and it may be necessary to call this method to flush any pending events.

      For performance reasons this method should not be called very often.

      Throws:
        `org.xml.sax.SAXException`
      See Also:
        `SerializationHandler.flushPending()`
