## org.apache.xml.serializer
Interface ExtendedContentHandler

All Known Subinterfaces:
  SerializationHandler

public interface ExtendedContentHandler
extends ContentHandler

This interface describes extensions to the SAX ContentHandler interface. It is intended to be used by a serializer. The methods on this interface will implement SAX- like behavior. This allows the gradual collection of information rather than having it all up front. For example the call

     startElement(namespaceURI,localName,qName,atts)

could be replaced with the calls

     startElement(namespaceURI,localName,qName)
     addAttributes(atts)

If there are no attributes the second call can be dropped. If attributes are to be added one at a time with calls to

     addAttribute(namespaceURI, localName, qName, type, value)

Usage:
  **For internal use only**

    `localName` - the local name of the attribute (without prefix)
    `rawName` - the qualified name of the attribute
    `type` - the attribute type typically character data (CDATA)

                       throws SAXException

  Add attributes to the current element
  Parameters:
    `atts` - the attributes to add.
  Throws:
    SAXException -

### addAttribute

    public void addAttribute(java.lang.String qName,
                             java.lang.String value)

  Add an attribute to the current element. The namespace URI of the attribute will be calculated from the prefix of qName. The local name will be derived from qName and the type will be assumed to be "CDATA".
  Parameters:
    `qName` -
    `value` -

### characters

    public void characters(java.lang.String chars)
                    throws SAXException

  This method is used to notify of a character event, but passing the data as a character String rather than the standard character array.
  Parameters:
    `chars` - the character data
  Throws:
    SAXException -

### characters

    public void characters(Node node)
                    throws SAXException

  This method is used to notify of a character event, but passing the data as a DOM Node rather than the standard character array.
  Parameters:
    `node` - a DOM Node containing text.
  Throws:
    SAXException -

### endElement

    public void endElement(java.lang.String elemName)
                    throws SAXException

  This method is used to notify that an element has ended. Unlike the standard SAX method

       endElement(namespaceURI,localName,qName)

  only the last parameter is passed. If needed the serializer can derive the localName from the qualified name and derive the namespaceURI from its implementation.
  Parameters:
    `elemName` - the fully qualified element name.
  Throws:
    SAXException -

### startElement

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

  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:
    `uri` - 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 qName)
                      throws SAXException

  This method is used to notify of the start of an element
  Parameters:
    `qName` - the fully qualified name of the element
  Throws:
    SAXException -

### namespaceAfterStartElement

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

  This method is used to notify that a prefix mapping is to start, but after an element is started. The SAX method call

       startPrefixMapping(prefix,uri)

  is used just before an element starts and applies to the element to come, not to the current element. This method applies to the current element. For example one could make the calls in this order:

       startElement("prfx8:elem9")
       namespaceAfterStartElement("http://namespace8","prfx8")

  Parameters:
    `uri` - the namespace URI being declared
    `prefix` - the prefix that maps to the given namespace
  Throws:
    SAXException -

### startPrefixMapping

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

  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 -

### entityReference

    public void entityReference(java.lang.String entityName)
                         throws SAXException

  Notify of an entity reference.
  Parameters:
    `entityName` - the name of the entity
  Throws:
    SAXException -

### getNamespaceMappings

    public NamespaceMappings getNamespaceMappings()

  This method returns an object that has the current namespace mappings in effect.
  Returns:
    NamespaceMappings an object that has the current namespace mappings in effect.

    public java.lang.String getNamespaceURI(java.lang.String name,
                                            boolean isElement)

  Parameters:
    `name` - the qualified name of an element, or attribute
    `isElement` - true if it is an element name, false if it is an atttribute name
  Returns:
    String the namespace URI associated with the element or attribute.

  This method returns the namespace URI currently associated with the prefix.
  Parameters:
    `prefix` - a prefix of an element or attribute.
  Returns:
    String the namespace URI currently associated with the prefix.

### setSourceLocator

    public void setSourceLocator(SourceLocator locator)

  This method is used to set the source locator, which might be used to generated an error message.
  Parameters:
    `locator` - the source locator

### addUniqueAttribute

    public void addUniqueAttribute(java.lang.String qName,
                                   java.lang.String value,
                                   int flags)
                            throws SAXException

  Add a unique attribute to the current element. The attribute is guaranteed to be unique here. The serializer can write it out immediately without saving it in a table first. The integer flag contains information about the attribute, which helps the serializer to decide whether a particular processing is needed.
  Parameters:
    `qName` - the fully qualified attribute name.
    `value` - the attribute value
    `flags` - a bitwise flag

### addXSLAttribute

    public void addXSLAttribute(java.lang.String qName,
                                java.lang.String value,
                                java.lang.String uri)

  Add an attribute from an xsl:attribute element.
  Parameters:
    `qName` - the qualified attribute name (prefix:localName)
    `value` - the attributes value
    `uri` - the uri that the prefix of the qName is mapped to.

### addAttribute

    public void addAttribute(java.lang.String uri,
                             java.lang.String localName,

  Parameters:
    `uri` - the namespace URI of the attribute name
    `localName` - the local name of the attribute (without prefix)
