Method Detail

isEmptyTag

protected static boolean isEmptyTag(String tag)

open

public void open()
          throws XPathException
Output start of document

Specified by:
open in interface Receiver
Overrides:
open in class XMLEmitter
Throws:
XPathException

openDocument

protected void openDocument()
                     throws XPathException
Description copied from class: XMLEmitter
Do the real work of starting the document. This happens when the first content is written.

Overrides:
openDocument in class XMLEmitter
Throws:
XPathException

writeDocType

protected void writeDocType(String type,
                            String systemId,
                            String publicId)
                     throws XPathException
Output the document type declaration

Overrides:
writeDocType in class XMLEmitter
Parameters:
type - The element name
systemId - The DOCTYP system identifier
publicId - The DOCTYPE public identifier
Throws:
XPathException

startElement

public void startElement(int nameCode,
                         int typeCode,
                         int locationId,
                         int properties)
                  throws XPathException
Output element start tag

Specified by:
startElement in interface Receiver
Overrides:
startElement in class XMLEmitter
Parameters:
nameCode - integer code identifying the name of the element within the name pool.
typeCode - integer code identifying the element's type within the name pool. The value -1 indicates the default type, xs:untyped.
locationId - an integer which can be interpreted using a LocationProvider to return information such as line number and system ID. If no location information is available, the value zero is supplied.
properties - bit-significant properties of the element node. If there are no revelant properties, zero is supplied. The definitions of the bits are in class ReceiverOptions
Throws:
XPathException

startContent

public void startContent()
                  throws XPathException
Description copied from interface: Receiver
Notify the start of the content, that is, the completion of all attributes and namespaces. Note that the initial receiver of output from XSLT instructions will not receive this event, it has to detect it itself. Note that this event is reported for every element even if it has no attributes, no namespaces, and no content.

Specified by:
startContent in interface Receiver
Overrides:
startContent in class XMLEmitter
Throws:
XPathException

writeAttribute

protected void writeAttribute(int elCode,
                              String attname,
                              CharSequence value,
                              int properties)
                       throws XPathException
Write attribute name=value pair. Overrides the XML behaviour if the name and value are the same (we assume this is a boolean attribute to be minimised), or if the value is a URL.

Overrides:
writeAttribute in class XMLEmitter
Parameters:
elCode - The element name is not used in this version of the method, but is used in the HTML subclass.
attname - The attribute name, which has already been validated to ensure it can be written in this encoding
value - The value of the attribute
properties - Any special properties of the attribute
Throws:
XPathException

writeEscape

protected void writeEscape(CharSequence chars,
                           boolean inAttribute)
                    throws IOException,
                           XPathException
Escape characters. Overrides the XML behaviour

Overrides:
writeEscape in class XMLEmitter
Parameters:
chars - The character sequence containing the string
inAttribute - Set to true if the text is in an attribute value
Throws:
IOException
XPathException

endElement

public void endElement()
                throws XPathException
Output an element end tag.

Specified by:
endElement in interface Receiver
Overrides:
endElement in class XMLEmitter
Throws:
XPathException

characters

public void characters(CharSequence chars,
                       int locationId,
                       int properties)
                throws XPathException
Character data.

Specified by:
characters in interface Receiver
Overrides:
characters in class XMLEmitter
Parameters:
chars - The characters
locationId - an integer which can be interpreted using a LocationProvider to return information such as line number and system ID. If no location information is available, the value zero is supplied.
properties - Bit significant value. The following bits are defined:
DISABLE_ESCAPING
Disable escaping for this text node
USE_CDATA
Output as a CDATA section
Throws:
XPathException

processingInstruction

public void processingInstruction(String target,
                                  CharSequence data,
                                  int locationId,
                                  int properties)
                           throws XPathException
Handle a processing instruction.

Specified by:
processingInstruction in interface Receiver
Overrides:
processingInstruction in class XMLEmitter
Parameters:
target - The PI name. This must be a legal name (it will not be checked).
data - The data portion of the processing instruction
locationId - an integer which can be interpreted using a LocationProvider to return information such as line number and system ID. If no location information is available, the value zero is supplied.
properties - Additional information about the PI. The following bits are defined:
CHECKED
Data is known to be legal (e.g. doesn't contain "?>")
Throws:
XPathException
