  - ### Method Detail

    - #### endDocument

          public void endDocument()
                           throws SAXException

      Receive notification of the end of a document.

      The SAX parser will invoke this method only once, and it will be the last method invoked during the parse. The parser shall not invoke this method until it has either abandoned parsing (because of an unrecoverable error) or reached the end of input.

      Throws:
        `SAXException` - Any SAX exception, possibly wrapping another exception.
        `SAXException`
      See Also:
        `ContentHandler.startDocument()`

    - #### startElement

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

      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.

      If the element name has a namespace prefix, the prefix will still be attached. Note that the attribute list provided will contain only attributes with explicit values (specified or defaulted): #IMPLIED attributes will be omitted.

      Specified by:
        `startElement` in interface `ContentHandler`
      Overrides:
        `startElement` in class `ToStream`
      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.
        `name` - The qualified name (with prefix), or the empty string if qualified names are not available.
        `atts` - The attributes attached to the element, if any.
      Throws:
        `SAXException` - Any SAX exception, possibly wrapping another exception.
        `SAXException`
      See Also:
        `endElement(java.lang.String, java.lang.String, java.lang.String)`, `AttributeList`

    - #### endElement

          public void endElement(java.lang.String namespaceURI,
                        java.lang.String localName,
                        java.lang.String name)
                          throws SAXException

      Receive notification of the end of an element.

      The SAX parser will invoke this method at the end of every element in the XML document; there will be a corresponding startElement() event for every endElement() event (even when the element is empty).

      If the element name has a namespace prefix, the prefix will still be attached to the name.

      Specified by:
        `endElement` in interface `ContentHandler`
      Overrides:
        `endElement` in class `ToStream`
      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.
        `name` - The qualified name (with prefix), or the empty string if qualified names are not available.
      Throws:
        `SAXException` - Any SAX exception, possibly wrapping another exception.
        `SAXException`

    - #### characters

          public void characters(char[] ch,
                        int start,
                        int length)
                          throws 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).

      Specified by:
        `characters` in interface `ContentHandler`
      Overrides:
        `characters` in class `ToStream`
      Parameters:
        `ch` - The characters from the XML document.
        `start` - The start position in the array.
        `length` - The number of characters to read from the array.
      Throws:
        `SAXException` - Any SAX exception, possibly wrapping another exception.
      See Also:
        `ignorableWhitespace(char[], int, int)`, `Locator`

    - #### charactersRaw

          public void charactersRaw(char[] ch,
                           int start,
                           int length)
                             throws SAXException

      If available, when the disable-output-escaping attribute is used, output raw text without escaping.
      Parameters:
        `ch` - The characters from the XML document.
        `start` - The start position in the array.
        `length` - The number of characters to read from the array.
      Throws:
        `SAXException` - Any SAX exception, possibly wrapping another exception.

    - #### cdata

          public void cdata(char[] ch,
                   int start,
                   int length)
                     throws SAXException

      Receive notification of cdata.

      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:
        `ch` - The characters from the XML document.
        `start` - The start position in the array.
        `length` - The number of characters to read from the array.
      Throws:
        `SAXException` - Any SAX exception, possibly wrapping another exception.
      See Also:
        `ignorableWhitespace(char[], int, int)`, `Locator`

    - #### ignorableWhitespace

          public void ignorableWhitespace(char[] ch,
                                 int start,
                                 int length)
                                   throws SAXException

      Receive notification of ignorable whitespace in element content.

      Validating Parsers must use this method to report each chunk of ignorable whitespace (see the W3C XML 1.0 recommendation, section 2.10): non-validating parsers may also use this method if they are capable of parsing and using content models.

      SAX parsers may return all contiguous whitespace 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.

      Specified by:
        `ignorableWhitespace` in interface `ContentHandler`
      Overrides:
        `ignorableWhitespace` in class `ToStream`

      Throws:
        `SAXException` - Any SAX exception, possibly wrapping another exception.
        `SAXException`

                                     throws SAXException

      Receive notification of a processing instruction.

      The Parser will invoke this method once for each processing instruction found: note that processing instructions may occur before or after the main document element.

      A SAX parser should never report an XML declaration (XML 1.0, section 2.8) or a text declaration (XML 1.0, section 4.3.1) using this method.

      Parameters:
        `target` - The processing instruction target.

                                     throws SAXException

      Description copied from class: `ToStream`
      Handle a prefix/uri mapping, which is associated with a startElement() that is soon to follow. Need to close any open start tag to make sure than any name space attributes due to this event are associated wih the up comming element, not the current one.
      Specified by:
        `startPrefixMapping` in interface `ExtendedContentHandler`
      Overrides:
        `startPrefixMapping` in class `ToStream`
      Parameters:
        `prefix` - The Namespace prefix being declared.
        `uri` - The Namespace URI the prefix is mapped to.
        `shouldFlush` - true if any open tags need to be closed first, this will impact which element the mapping applies to (open parent, or its up comming child)
      Returns:
        returns true if the call made a change to the current namespace information, false if it did not change anything, e.g. if the prefix/namespace mapping was already in scope from before.
      Throws:

      Specified by:
        `startPrefixMapping` in interface `ContentHandler`
      Overrides:
        `startPrefixMapping` in class `ToStream`
