All Implemented Interfaces:

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.

Constructor Detail

UncommittedSerializer

public UncommittedSerializer(Result finalResult,
                             Properties outputProperties)
Create an uncommitted Serializer

Parameters:
finalResult - the output destination
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

close

public void close()
           throws XPathException
End of document

Specified by:
close in interface Receiver
Overrides:
close in class ProxyReceiver
Throws:
XPathException

characters

public void characters(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

processingInstruction

public void processingInstruction(String target,
                                  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

comment

public void comment(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

startElement

public void startElement(int nameCode,
                         int 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:
nameCode - 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
