public class XMLIndenter
extends ProxyReceiver

XMLIndenter: This ProxyReceiver indents elements, by adding character data where appropriate. The character data is always added as "ignorable white space", that is, it is never added adjacent to existing character data.

Method Detail

setOutputProperties

public void setOutputProperties(Properties props)

Set the properties for this indenter

Parameters:

props - the serialization properties

open

public void open()
          throws XPathException

Start of document

Specified by:

open in interface Receiver

Overrides:

open in class ProxyReceiver

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 ProxyReceiver

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.

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 - properties of the element node

Throws:

XPathException

attribute

public void attribute(int nameCode,
                      int typeCode,
                      CharSequence value,
                      int locationId,
                      int properties)
               throws XPathException

Output an attribute

Specified by:

attribute in interface Receiver

Overrides:

attribute in class ProxyReceiver

Parameters:

nameCode - The name of the attribute, as held in the name pool

typeCode - The type of the attribute, as held in the name pool

value - the string value of the attribute

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 attribute

NO_SPECIAL_CHARACTERS

Attribute value contains no special characters

Throws:

XPathException

endElement

public void endElement()
                throws XPathException

Output element end tag

Specified by:

endElement in interface Receiver

Overrides:

endElement in class ProxyReceiver

Throws:

XPathException

processingInstruction

public void processingInstruction(String target,
                                  CharSequence data,
                                  int locationId,

                           throws XPathException

Output a processing instruction

Specified by:

processingInstruction in interface Receiver

Overrides:

processingInstruction in class ProxyReceiver

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

Disable escaping for this text node

USE_CDATA

Output as a CDATA section

Throws:

XPathException

comment

public void comment(CharSequence chars,
