setSecondDestination

protected void setSecondDestination(Receiver seq2)

Set the second destination

Parameters:

seq2 - the second output destination

getFirstDestination

protected Receiver getFirstDestination()

Get the first destination

setUnparsedEntity

public void setUnparsedEntity(String name,
 String systemID,
 String publicID)
                       throws XPathException

Pass on information about unparsed entities

Specified by:

setUnparsedEntity in interface Receiver

Overrides:

setUnparsedEntity in class SequenceReceiver

Parameters:

name - The name of the unparsed entity

systemID - The system identifier of the unparsed entity

publicID - The public identifier of the unparsed entity

Throws:

XPathException - in the event of an error

append

public void append(Item item,
 Location locationId,
 int properties)
            throws XPathException

Output an item (atomic value or node) to the sequence

Specified by:

append in interface Receiver

Specified by:

append in class SequenceReceiver

Parameters:

item - the item to be appended

locationId - the location of the calling instruction, for diagnostics

properties - if the item is an element node, this indicates whether its namespaces need to be copied. Values are ReceiverOption.ALL_NAMESPACES; the default (0) means

Throws:

XPathException - if an error occurs

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

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

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

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

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

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 - 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:

Throws:

XPathException - if an error occurs

processingInstruction

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

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 - 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:

IllegalArgumentException - the content is invalid for an XML processing instruction

XPathException - if an error occurs

comment

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

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

Parameters:

content - 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:

IllegalArgumentException - the content is invalid for an XML comment

XPathException - if an error occurs

close

public void close()
           throws XPathException

Notify the end of the event stream

Throws:

XPathException - if an error occurs

usesTypeAnnotations

public boolean usesTypeAnnotations()

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

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
