## org.apache.xml.serializer
Class ToUnknownStream

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

All Implemented Interfaces:
  ContentHandler, DeclHandler, DOM2DTM.CharacterNodeHandler, DOMSerializer, ErrorHandler, ExtendedContentHandler, ExtendedLexicalHandler, LexicalHandler, SerializationHandler, Serializer, SerializerConstants, XSLOutputAttributes

public 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.

                            throws SAXException

  Description copied from interface: `ContentHandler`
  Begin the scope of a prefix-URI Namespace mapping.

  The information from this event is not necessary for normal Namespace processing: the SAX XML reader will automatically replace prefixes for element and attribute names when the `http://xml.org/sax/features/namespaces` feature is true (the default).

  There are cases, however, when applications need to use prefixes in character data or in attribute values, where they cannot safely be expanded automatically; the start/endPrefixMapping event supplies the information to the application to expand prefixes in those contexts itself, if necessary.

  Note that start/endPrefixMapping events are not guaranteed to be properly nested relative to each other: all startPrefixMapping events will occur immediately before the corresponding `startElement` event, and all `endPrefixMapping` events will occur immediately after the corresponding `endElement` event, but their order is not otherwise guaranteed.

  There should never be start/endPrefixMapping events for the "xml" prefix, since it is predeclared and immutable.

  Parameters:
    `prefix` - The prefix that maps to the URI
    `uri` - The URI for the namespace
  Throws:
    `SAXException` - The client may throw an exception during processing.
  See Also:
    `ContentHandler.startPrefixMapping(String, String)`

### namespaceAfterStartElement

    public void namespaceAfterStartElement(java.lang.String prefix,
                                           java.lang.String uri)
                                    throws SAXException

  This method is used when a prefix/uri namespace mapping is indicated after the element was started with a startElement() and before and endElement(). startPrefixMapping(prefix,uri) would be used before the startElement() call.

  Specified by:
    `namespaceAfterStartElement` in interface `ExtendedContentHandler`
  Overrides:
    `namespaceAfterStartElement` in class `SerializerBase`
  Parameters:
    `uri` - the URI of the namespace
    `prefix` - the prefix associated with the given URI.
  Throws:
    `SAXException`
  See Also:
    `ExtendedContentHandler.namespaceAfterStartElement(String, String)`

### startPrefixMapping

    public boolean startPrefixMapping(java.lang.String prefix,
                                      java.lang.String uri,
                                      boolean shouldFlush)
                               throws 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:
    `SAXException`

### setVersion

    public void setVersion(java.lang.String version)

  This method cannot be cached because default is different in HTML and XML (we need more than a boolean).

  Specified by:
    `setVersion` in interface `XSLOutputAttributes`
  Overrides:
    `setVersion` in class `SerializerBase`
  Parameters:
    `version` - the version of the output format.
  See Also:
    `XSLOutputAttributes.setVersion(String)`

  The SAX parser will invoke this method only once, before any other methods in this interface or in DTDHandler (except for setDocumentLocator).

  Specified by:
    `startDocument` in interface `ContentHandler`
  Overrides:
    `startDocument` in class `SerializerBase`
  Throws:
    `SAXException` - Any SAX exception, possibly wrapping another exception.
  See Also:
    `ContentHandler.startDocument()`

### startElement

    public void startElement(java.lang.String qName)
                      throws SAXException

  Description copied from interface: `ExtendedContentHandler`
  This method is used to notify of the start of an element

  Parameters:
    `qName` - the fully qualified name of the element
  Throws:
    `SAXException`

### startElement

    public void startElement(java.lang.String namespaceURI,

                             java.lang.String qName)
                      throws SAXException

  Description copied from interface: `ExtendedContentHandler`
  This method is used to notify that an element is starting. This method is just like the standard SAX method

       startElement(uri,localName,qname,atts)

  but without the attributes.

  Parameters:
    `namespaceURI` - the namespace URI of the element
    `localName` - the local name (without prefix) of the element
    `qName` - the qualified name of the element
  Throws:
    `SAXException`

### startElement

    public void startElement(java.lang.String namespaceURI,
                             java.lang.String localName,
                             java.lang.String elementName,
                             Attributes atts)
                      throws SAXException

  Description copied from interface: `ContentHandler`
  Receive notification of the beginning of an element.

  The Parser will invoke this method at the beginning of every element in the XML document; there will be a corresponding `endElement` event for every startElement event (even when the element is empty). All of the element's content will be reported, in order, before the corresponding endElement event.

  This event allows up to three name components for each element:

  1. the Namespace URI;
  2. the local name; and
  3. the qualified (prefixed) name.

  Any or all of these may be provided, depending on the values of the http://xml.org/sax/features/namespaces and the http://xml.org/sax/features/namespace-prefixes properties:

  - the Namespace URI and local name are required when the namespaces property is true (the default), and are optional when the namespaces property is false (if one is specified, both must be);
  - the qualified name is required when the namespace-prefixes property is true, and is optional when the namespace-prefixes property is false (the default).

  Note that the attribute list provided will contain only attributes with explicit values (specified or defaulted): #IMPLIED attributes will be omitted. The attribute list will contain attributes used for Namespace declarations (xmlns* attributes) only if the `http://xml.org/sax/features/namespace-prefixes` property is true (it is false by default, and support for a true value is optional).

  Like `characters()`, attribute values may have characters that need more than one `char` value.

  Parameters:
    `namespaceURI` - The Namespace URI, or the empty string if the element has no Namespace URI or if Namespace processing is not being performed.
    `localName` - The local name (without prefix), or the empty string if Namespace processing is not being performed.
    `elementName` - The qualified name (with prefix), or the empty string if qualified names are not available.
    `atts` - The attributes attached to the element. If there are no attributes, it shall be an empty Attributes object.
  Throws:
    `SAXException` - Any SAX exception, possibly wrapping another exception.
  See Also:
    `ContentHandler.endElement(java.lang.String, java.lang.String, java.lang.String)`, `Attributes`

  Pass the call on to the underlying handler

  Specified by:
    `setDocumentLocator` in interface `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.

    `ContentHandler.setDocumentLocator(Locator)`
