Package net.sf.saxon.serialize

Class UncommittedSerializer

java.lang.Object

net.sf.saxon.event.SequenceReceiver

net.sf.saxon.event.ProxyReceiver

net.sf.saxon.serialize.UncommittedSerializer

All Implemented Interfaces:

javax.xml.transform.Result, Receiver

public class UncommittedSerializer
extends ProxyReceiver

This class is used when the decision on which serialization method to use has to be delayed until the first element is read. It buffers comments and processing instructions until that happens; then when the first element arrives it creates a real serialization pipeline and uses that for future output.

UncommittedSerializer

public UncommittedSerializer(javax.xml.transform.Result finalResult,
                             Receiver next,
                             java.util.Properties outputProperties)

Create an uncommitted Serializer

Parameters:

finalResult - the output destination

next - the next receiver in the pipeline

outputProperties - the serialization properties

Method Detail

open

public void open()
          throws XPathException

Description copied from class: ProxyReceiver

Start of event stream

Specified by:

open in interface Receiver

Overrides:

open in class ProxyReceiver

Throws:

XPathException - if an error occurs

close

public void close()
           throws XPathException

End of document

Specified by:

close in interface Receiver

Overrides:

close in class ProxyReceiver

Throws:

XPathException - if an error occurs

characters

public void characters(java.lang.CharSequence chars,
                       int locationId,
                       int properties)
                throws XPathException

Produce character output using the current Writer.

Specified by:

characters in interface Receiver

Overrides:

characters in class ProxyReceiver

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 - if an error occurs

processingInstruction

public void processingInstruction(java.lang.String target,
                                  java.lang.CharSequence data,
                                  int locationId,
                                  int properties)
                           throws XPathException

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.

Throws:

XPathException - if an error occurs

comment

public void comment(java.lang.CharSequence chars,
                    int locationId,
                    int properties)
             throws XPathException

Output a comment

Specified by:

comment in interface Receiver

Overrides:

comment in class ProxyReceiver

Parameters:

chars - The content of the comment

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 comment.

Throws:

XPathException - if an error occurs

startElement

public void startElement(NodeName elemName,
                         SchemaType typeCode,
                         int locationId,
                         int properties)
                  throws XPathException

Output an element start tag.
This can only be called once: it switches to a substitute output generator for XML, XHTML, or HTML, depending on the element name.

Specified by:

startElement in interface Receiver

Overrides:

startElement in class ProxyReceiver

Parameters:

elemName - The element name (tag)

typeCode - The type annotation

properties - Bit field holding special properties of the element

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.

Throws:

XPathException - if an error occurs
