public interface Receiver
extends javax.xml.transform.Result

Receiver: This interface represents a recipient of XML tree-walking events. It is based on SAX2's ContentHandler, but adapted to handle additional events, and to use Saxon's name pool. Namespaces and Attributes are handled by separate events following the startElement event. Schema types can be defined for elements and attributes. This interface is designed as an eventual replacement for the old Emitter class, as well as the Outputter interface. The name change from "Emitter" to "Receiver" reflects that the essence of the interface is that all implementations receive notification of these events; they do very different things with the events once recieved.

Method Detail

setNamePool

public void setNamePool(NamePool namePool)
Set the namePool in which all name codes can be found


getNamePool

public NamePool getNamePool()
Get the namePool in which all name codes can be found


setSystemId

public void setSystemId(java.lang.String systemId)
Set the System ID of the destination tree

Specified by:
setSystemId in interface javax.xml.transform.Result

setDocumentLocator

public void setDocumentLocator(org.xml.sax.Locator locator)
                        throws javax.xml.transform.TransformerException
Set locator, to identify position in the document. A new locator may be supplied at any time. It is not necessary to supply any locator. If a locator is supplied, it may be used by the Receiver to obtain information about the location of the current event in a source XML document.

javax.xml.transform.TransformerException

startDocument

public void startDocument()
                   throws javax.xml.transform.TransformerException
Notify the start of the document

javax.xml.transform.TransformerException

setUnparsedEntity

public void setUnparsedEntity(java.lang.String name,
                              java.lang.String systemID,
                              java.lang.String publicID)
                       throws javax.xml.transform.TransformerException
Notify an unparsed entity URI.

Parameters:
name - The name of the unparsed entity
systemID - The system identifier of the unparsed entity
publicID - The public identifier of the unparsed entity
javax.xml.transform.TransformerException

startElement

public void startElement(int nameCode,
                         int typeCode,
                         int properties)
                  throws javax.xml.transform.TransformerException
Notify the start of an element

Parameters:
nameCode - integer code identifying the name of the element within the name pool.
typeCode - integer code identifying the element's type within the name pool.
javax.xml.transform.TransformerException

namespace

public void namespace(int namespaceCode,
                      int properties)
               throws javax.xml.transform.TransformerException
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.
Throws:
IllegalStateException: - attempt to output a namespace when there is no open element start tag
javax.xml.transform.TransformerException

attribute

public void attribute(int nameCode,
                      int typeCode,
                      java.lang.CharSequence value,
                      int properties)
               throws javax.xml.transform.TransformerException
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
Throws:
IllegalStateException: - attempt to output an attribute when there is no open element start tag
javax.xml.transform.TransformerException

startContent

public void startContent()
                  throws javax.xml.transform.TransformerException
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.

javax.xml.transform.TransformerException

endElement

public void endElement()
                throws javax.xml.transform.TransformerException
Notify the end of an element. The receiver must maintain a stack if it needs to know which element is ending.

javax.xml.transform.TransformerException

characters

public void characters(java.lang.CharSequence chars,
                       int properties)
                throws javax.xml.transform.TransformerException
Notify character data. Note that some receivers may require the character data to be sent in a single event, but in general this is not a requirement.

Parameters:
chars - The characters
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
javax.xml.transform.TransformerException

                           throws javax.xml.transform.TransformerException
