public interface ExtendedContentHandler
extends org.xml.sax.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)

Method Detail

addAttribute

void addAttribute(java.lang.String uri,
                  java.lang.String localName,
                  java.lang.String rawName,
                  java.lang.String type,
                  java.lang.String value,
                  boolean XSLAttribute)
                  throws org.xml.sax.SAXException
Add at attribute to the current element

Parameters:
uri - the namespace URI of the attribute name
localName - the local name of the attribute (without prefix)
rawName - the qualified name of the attribute
type - the attribute type typically character data (CDATA)
value - the value of the attribute
XSLAttribute - true if the added attribute is coming from an xsl:attribute element
Throws:
org.xml.sax.SAXException

addAttributes

void addAttributes(org.xml.sax.Attributes atts)
                   throws org.xml.sax.SAXException
Add attributes to the current element

Parameters:
atts - the attributes to add.
Throws:
org.xml.sax.SAXException

addAttribute

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

void characters(java.lang.String chars)
                throws org.xml.sax.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:
org.xml.sax.SAXException

characters

void characters(org.w3c.dom.Node node)
                throws org.xml.sax.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:
org.xml.sax.SAXException

endElement

void endElement(java.lang.String elemName)
                throws org.xml.sax.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:
org.xml.sax.SAXException

startElement

void startElement(java.lang.String uri,
                  java.lang.String localName,
                  java.lang.String qName)
                  throws org.xml.sax.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:
org.xml.sax.SAXException

startElement

void startElement(java.lang.String qName)
                  throws org.xml.sax.SAXException
This method is used to notify of the start of an element

Parameters:
qName - the fully qualified name of the element
Throws:
org.xml.sax.SAXException

namespaceAfterStartElement

void namespaceAfterStartElement(java.lang.String uri,
                                java.lang.String prefix)
                                throws org.xml.sax.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:
org.xml.sax.SAXException

startPrefixMapping

boolean startPrefixMapping(java.lang.String prefix,
                           java.lang.String uri,
                           boolean shouldFlush)
                           throws org.xml.sax.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:
org.xml.sax.SAXException

entityReference

void entityReference(java.lang.String entityName)
                     throws org.xml.sax.SAXException
Notify of an entity reference.

Parameters:
entityName - the name of the entity
Throws:
org.xml.sax.SAXException

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.

getPrefix

java.lang.String getPrefix(java.lang.String uri)
This method returns the prefix that currently maps to the given namespace URI.

Parameters:
uri - the namespace URI
Returns:
String the prefix that currently maps to the given URI.

getNamespaceURI

java.lang.String getNamespaceURI(java.lang.String name,
                                 boolean isElement)
This method gets the prefix associated with a current element or attribute name.

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

setSourceLocator

void setSourceLocator(javax.xml.transform.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

void addUniqueAttribute(java.lang.String qName,
                        java.lang.String value,
                        int flags)
                        throws org.xml.sax.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
Throws:
org.xml.sax.SAXException

addXSLAttribute

void addXSLAttribute(java.lang.String qName,

                     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

void addAttribute(java.lang.String uri,
                  java.lang.String localName,
                  java.lang.String rawName,
                  java.lang.String type,
                  java.lang.String value)
                  throws org.xml.sax.SAXException
Add at attribute to the current element, not from an xsl:attribute element.

Parameters:
uri - the namespace URI of the attribute name
localName - the local name of the attribute (without prefix)
rawName - the qualified name of the attribute
type - the attribute type typically character data (CDATA)
value - the value of the attribute
Throws:
org.xml.sax.SAXException
