TEXTEmitter

public TEXTEmitter()

Method Detail

open

public void open()
          throws XPathException

Start of the document.

Specified by:

open in interface Receiver

Overrides:

open in class XMLEmitter

Throws:

XPathException

writeDeclaration

public void writeDeclaration()
                      throws XPathException

Output the XML declaration. This implementation does nothing.

Overrides:

writeDeclaration in class XMLEmitter

Throws:

XPathException

characters

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

Produce output using the current Writer.
Special characters are not escaped.

Specified by:

characters in interface Receiver

Overrides:

characters in class XMLEmitter

Parameters:

chars - Character sequence to be output

properties - bit fields holding special properties of 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.

Throws:

XPathException - for any failure

startElement

public void startElement(int nameCode,
                         int typeCode,
                         int locationId,
                         int properties)

Output an element start tag.
Does nothing with this output method.

Specified by:

startElement in interface Receiver

Overrides:

startElement in class XMLEmitter

Parameters:

nameCode - The element name (tag)

typeCode - The type annotation

properties - Bit fields holding any 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.

namespace

public void namespace(int namespaceCode,
                      int properties)

Description copied from interface: Receiver

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. The events represent namespace declarations and undeclarations rather than in-scope namespace nodes: an undeclaration is represented by a namespace code of zero. If the sequence of namespace events contains two A namespace must not conflict with any namespaces already used for element or attribute names.

Specified by:

namespace in interface Receiver

Overrides:

namespace in class XMLEmitter

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.

attribute

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

Description copied from interface: Receiver

Notify an attribute. Attributes are notified after the startElement event, and before any children. Namespaces and attributes may be intermingled.

Specified by:

attribute in interface Receiver

Overrides:

attribute in class XMLEmitter

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. The additional bit NodeInfo.IS_DTD_TYPE may be set to indicate a DTD-derived type.

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

endElement

public void endElement()

Output an element end tag.
Does nothing with this output method.

Specified by:

endElement in interface Receiver

Overrides:

endElement in class XMLEmitter

processingInstruction

public void processingInstruction(String name,
                                  CharSequence value,
                                  int locationId,
                                  int properties)
                           throws XPathException

Output a processing instruction.
Does nothing with this output method.

Specified by:

processingInstruction in interface Receiver

Overrides:

processingInstruction in class XMLEmitter

Parameters:

name - The PI name. This must be a legal name (it will not be checked).

value - The data portion of the processing instruction
