public UncommittedEmitter()
Method Detail

open

public void open()
          throws XPathException
Description copied from interface: Receiver
Notify the start of the event stream

Throws:
XPathException

close

public void close()
           throws XPathException
End of document

Throws:
XPathException

startDocument

public void startDocument(int properties)
                   throws XPathException
Start of a document node. Nothing is done at this stage: the opening of the output file is deferred until some content is written to it.

XPathException

endDocument

public void endDocument()
                 throws XPathException
Notify the end of a document node

Throws:
XPathException

characters

public void characters(java.lang.CharSequence chars,
                       int locationId,
                       int properties)
                throws XPathException
Produce character output using the current Writer.

Parameters:
chars - The characters
locationId - an integer which can be interpreted using a LocationMap 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
NO_SPECIAL_CHARACTERS
Value contains no special characters
WHITESPACE
Text is all whitespace
Throws:
XPathException

processingInstruction

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

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 LocationMap 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

comment

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

Parameters:
chars - The content of the comment
locationId - an integer which can be interpreted using a LocationMap 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. The following bits are defined:
CHECKED
Comment is known to be legal (e.g. doesn't contain "--")
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 or HTML, depending on whether the tag is "HTML".

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 LocationMap to return information such as line number and system ID. If no location information is available, the value zero is supplied.
Throws:
XPathException

namespace

public void namespace(int namespaceCode,
                      int properties)
               throws XPathException
Notify a namespace. Namespaces are notified after the startElement event, and before any children for the element. The namespaces that are reported are only required to include those that are different from the parent element; however, duplicates may be reported. A namespace must not conflict with any namespaces already used for element or attribute names.

Parameters:
namespaceCode - an integer: the top half is a prefix code, the bottom half a URI code. These may be translated into an actual prefix and URI using the name pool. A prefix code of zero represents the empty prefix (that is, the default namespace). A URI code of zero represents a URI of "", that is, a namespace undeclaration.
properties - The most important property is REJECT_DUPLICATES. If this property is set, the namespace declaration will be rejected if it conflicts with a previous declaration of the same prefix. If the property is not set, the namespace declaration will be ignored if it conflicts with a previous declaration. This reflects the fact that when copying a tree, namespaces for child elements are emitted before the namespaces of their parent element. Unfortunately this conflicts with the XSLT rule for complex content construction, where the recovery action in the event of conflicts is to take the namespace that comes last. XSLT therefore doesn't recover from this error: it sets the REJECT_DUPLICATES flag, and this is treated as a hard error.
Throws:
IllegalStateException: - attempt to output a namespace when there is no open element start tag
XPathException

attribute

public void attribute(int nameCode,
                      int typeCode,
                      java.lang.CharSequence value,
                      int locationId,
                      int properties)
               throws XPathException
Notify an attribute. Attributes are notified after the startElement event, and before any children. Namespaces and attributes may be intermingled.

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
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
locationId - an integer which can be interpreted using a LocationMap to return information such as line number and system ID. If no location information is available, the value zero is supplied.
Throws:
IllegalStateException: - attempt to output an attribute when there is no open element start tag
XPathException

startContent

public void startContent()
                  throws XPathException
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.

Throws:
XPathException

endElement

public void endElement()
                throws XPathException
End of element

Throws:
XPathException
