All Implemented Interfaces:

javax.xml.transform.Result, Receiver

Direct Known Subclasses:

XMLIndenterPE

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.

Constructor Detail

XMLIndenter

public XMLIndenter(XMLEmitter next)

Create an XML Indenter

Parameters:

next - the next receiver in the pipeline, always an XMLEmitter

Method Detail

setOutputProperties

public void setOutputProperties(java.util.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 - if an error occurs

startElement

public void startElement(NodeName nameCode,
                         SchemaType type,
                         AttributeMap attributes,
                         NamespaceMap namespaces,
                         Location location,
                         int properties)
                  throws XPathException

Output element start tag

Specified by:

startElement in interface Receiver

Overrides:

startElement in class ProxyReceiver

Parameters:

nameCode - the name of the element.

type - the type annotation of the element.

attributes - the attributes of this element

namespaces - the in-scope namespaces of this element: generally this is all the in-scope namespaces, without relying on inheriting namespaces from parent elements

location - an object providing information about the module, line, and column where the node originated

properties - bit-significant properties of the element node. If there are no relevant properties, zero is supplied. The definitions of the bits are in class ReceiverOption

Throws:

XPathException - if an error occurs

endElement

public void endElement()
                throws XPathException

Output element end tag

Specified by:

endElement in interface Receiver

Overrides:

endElement in class ProxyReceiver

Throws:

XPathException - if an error occurs

processingInstruction

public void processingInstruction(java.lang.String target,
                                  UnicodeString data,
                                  Location locationId,
                                  int properties)
                           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 - provides information such as line number and system ID.

properties - Additional information about the PI.

Throws:

XPathException - if an error occurs

characters

public void characters(UnicodeString chars,
                       Location locationId,
                       int properties)
                throws XPathException

Output character data

Specified by:

characters in interface Receiver

Overrides:

characters in class ProxyReceiver

Parameters:

chars - The characters

locationId - provides information such as line number and system ID.

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 - if an error occurs

comment

public void comment(UnicodeString chars,
                    Location locationId,

Specified by:

usesTypeAnnotations in interface Receiver

Overrides:

usesTypeAnnotations in class ProxyReceiver

getIndentation

protected int getIndentation()

Get the number of spaces to be used for indentation

Returns:

the number of spaces to be added to the indentation for each level

isDoubleSpaced

protected boolean isDoubleSpaced(NodeName name)
