ProcessorCharacters

public ProcessorCharacters()
Method Detail

startNonText

public void startNonText(StylesheetHandler handler)
                  throws org.xml.sax.SAXException
Receive notification of the start of the non-text event. This is sent to the current processor when any non-text event occurs.

Overrides:
startNonText in class XSLTElementProcessor
Parameters:
handler - non-null reference to current StylesheetHandler that is constructing the Templates.
Throws:
org.xml.sax.SAXException

characters

public void characters(StylesheetHandler handler,
                       char[] ch,
                       int start,
                       int length)
                throws org.xml.sax.SAXException
Receive notification of character data inside an element.

Overrides:
characters in class XSLTElementProcessor
Parameters:
handler - non-null reference to current StylesheetHandler that is constructing the Templates.
ch - The characters.
start - The start position in the character array.
length - The number of characters to use from the character array.
Throws:
org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.

ContentHandler.characters(char[], int, int)

endElement

public void endElement(StylesheetHandler handler,
                       String uri,
                       String localName,
                       String rawName)
                throws org.xml.sax.SAXException
Receive notification of the end of an element.

Overrides:
endElement in class XSLTElementProcessor
Parameters:
handler - The calling StylesheetHandler/TemplatesBuilder.
uri - 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.
rawName - The raw XML 1.0 name (with prefix), or the empty string if raw names are not available.
Throws:
org.xml.sax.SAXException

setXslTextElement

void setXslTextElement(ElemText xslTextElement)
Set the current setXslTextElement. The xsl:text processor will call this to set a preserve space state.

Parameters:
xslTextElement - The current xslTextElement that is preserving state, or null.
