public boolean addAttributeAlways(String uri, String localName, String rawName, String type, String value, boolean xslAttribute)
Adds the given attribute to the set of attributes, even if there is no currently open element. This is useful if a SAX startPrefixMapping() should need to add an attribute before the element name is seen. This method is a copy of its super classes method, except that some tracing of events is done. This is so the tracing is only done for stream serializers, not for SAX ones.
- Overrides:
- addAttributeAlways in interface SerializerBase
- Parameters:
uri
- the URI of the attributelocalName
- the local name of the attributerawName
- the qualified name of the attributetype
- the type of the attribute (probably CDATA)value
- the value of the attributexslAttribute
- true if this attribute is coming from an xsl:attribute element.
- Returns:
- true if the attribute value was added, false if the attribute already existed and the value was replaced with the new value.
public void attributeDecl(String eName, String aName, String type, String valueDefault, String value) throws SAXException
Report an attribute type declaration. Only the effective (first) declaration for an attribute will be reported. The type will be one of the strings "CDATA", "ID", "IDREF", "IDREFS", "NMTOKEN", "NMTOKENS", "ENTITY", "ENTITIES", or "NOTATION", or a parenthesized token group with the separator "|" and all whitespace removed.
- Parameters:
eName
- The name of the associated element.aName
- The name of the attribute.type
- A string representing the attribute type.valueDefault
- A string representing the attribute default ("#IMPLIED", "#REQUIRED", or "#FIXED") or null if none of these applies.value
- A string representing the attribute's default value, or null if there is none.
public void characters(String s) throws org.xml.sax.SAXException
Receive notification of character data.
- Specified by:
- characters in interface org.apache.xml.serializer.ExtendedContentHandler
- Parameters:
s
- The string of characters to process.
public void characters(chars[] , int start, int length) throws org.xml.sax.SAXException
Receive notification of character data. The Parser will call this method to report each chunk of character data. SAX parsers may return all contiguous character data in a single chunk, or they may split it into several chunks; however, all of the characters in any single event must come from the same external entity, so that the Locator provides useful information. The application must not attempt to read from the array outside of the specified range. Note that some parsers will report whitespace using the ignorableWhitespace() method rather than this one (validating parsers must do so).
- Parameters:
start
- The start position in the array.length
- The number of characters to read from the array.
- See Also:
ignorableWhitespace(ch[],int,int)
,org.xml.sax.Locator
public void comment(ch[] , int start, int length) throws org.xml.sax.SAXException

- Parameters:
start
- The starting position in the array.length
- The number of characters to use from the array.
public void elementDecl(String name, String model) throws SAXException
Report an element type declaration. The content model will consist of the string "EMPTY", the string "ANY", or a parenthesised group, optionally followed by an occurrence indicator. The model will be normalized so that all whitespace is removed,and will include the enclosing parentheses.
- Parameters:
name
- The element type name.model
