BinaryEmitter

public BinaryEmitter(javax.xml.transform.stream.StreamResult streamResult,
                     PipelineConfiguration pipe)
              throws XPathException

Throws:

XPathException

Method Detail

open

public void open()
          throws XPathException

Description copied from class: SequenceReceiver

Start the output process

Specified by:

open in interface Receiver

Overrides:

open in class SequenceReceiver

Throws:

XPathException - if an error occurs

startDocument

public void startDocument(int properties)
                   throws XPathException

Description copied from interface: Receiver

Notify the start of a document node

Parameters:

properties - bit-significant integer indicating properties of the document node. The definitions of the bits are in class ReceiverOption

Throws:

XPathException - if an error occurs

endDocument

public void endDocument()
                 throws XPathException

Description copied from interface: Receiver

Notify the end of a document node

Throws:

XPathException - if an error occurs

startElement

public void startElement(NodeName elemName,
                         SchemaType type,
                         AttributeMap attributes,
                         NamespaceMap namespaces,
                         Location location,
                         int properties)
                  throws XPathException

Description copied from interface: Receiver

Notify the start of an element

Parameters:

elemName - the name of the element.

type - the type annotation of the element.

attributes - the attributes of this element

namespaces - the in-scope namespaces of this element: generally this is all the in-scope namespaces, without relying on inheriting namespaces from parent elements

location - an object providing information about the module, line, and column where the node originated

properties - bit-significant properties of the element node. If there are no relevant properties, zero is supplied. The definitions of the bits are in class ReceiverOption

Throws:

XPathException - if an error occurs

endElement

public void endElement()
                throws XPathException

Description copied from interface: Receiver

Notify the end of an element. The receiver must maintain a stack if it needs to know which element is ending.

Throws:

XPathException - if an error occurs

characters

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

Description copied from interface: Receiver

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

locationId - provides information such as line number and system ID.

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

textNodeToBinary

protected abstract byte[] textNodeToBinary(UnicodeString chars)
                                    throws XPathException

Throws:

XPathException

processingInstruction

public void processingInstruction(java.lang.String name,
                                  UnicodeString data,
                                  Location locationId,
                                  int properties)
                           throws XPathException

Description copied from interface: Receiver

Output a processing instruction

Parameters:

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

data - The data portion of the processing instruction

locationId - provides information such as line number and system ID.

properties - Additional information about the PI.

Throws:

XPathException - if an error occurs

comment

public void comment(UnicodeString content,
                    Location locationId,
                    int properties)
             throws XPathException

Description copied from interface: Receiver

Notify a comment. Comments are only notified if they are outside the DTD.

Parameters:

content - The content of the comment

locationId - provides information such as line number and system ID.

properties - Additional information about the comment.

Throws:

XPathException - if an error occurs

close

public void close()
           throws XPathException

Notify the end of the event stream

Specified by:

close in interface Receiver

Overrides:

close in class Emitter

Throws:

XPathException - if an error occurs

usesTypeAnnotations

public boolean usesTypeAnnotations()

Description copied from class: Emitter

Ask whether this Receiver (or the downstream pipeline) makes any use of the type annotations supplied on element and attribute events

Specified by:

usesTypeAnnotations in interface Receiver

Overrides:

usesTypeAnnotations in class Emitter

Returns:

true if the Receiver makes any use of this information. If false, the caller may supply untyped nodes instead of supplying the type annotation (or conversely, it may avoid stripping unwanted type annotations)

makeOutputStream

protected java.io.OutputStream makeOutputStream(javax.xml.transform.stream.StreamResult streamResult)
                                         throws XPathException

Throws:

XPathException
