Class SequenceWrapper
- Receiver, Result
public class SequenceWrapper
This class can be used in a push pipeline: it accepts any sequence as input, and generates
a document in which the items of the sequence are wrapped by elements containing information about
the types of the items in the input sequence.
void | append(Item item, int locationId, int copyNamespaces) - Output an item (atomic value or node) to the sequence
|
void | attribute(int nameCode, int typeCode, CharSequence value, int locationId, int properties) - Notify an attribute.
|
void | characters(CharSequence chars, int locationId, int properties) - Character data
|
void | close() - Notify the end of the event stream
|
void | comment(CharSequence chars, int locationId, int properties) - Output a comment
|
void | endDocument() - Notify the end of a document node
|
void | endElement() - End of element
|
void | namespace(int namespaceCode, int properties) - Notify a namespace.
|
void | open()
|
void | processingInstruction(String target, CharSequence data, int locationId, int properties) - Processing Instruction
|
void | startContent() - Notify the start of the content, that is, the completion of all attributes and namespaces.
|
void | startDocument(int properties) - Start of a document node.
|
void | startElement(int nameCode, int typeCode, int locationId, int properties) - Notify the start of an element

SequenceWrapper
public SequenceWrapper(Receiver destination)
Create a sequence wrapper. This creates an XML representation of the items sent to destination
in which the types of all items are made explicit
destination
- the sequence being wrapped
attribute
public void attribute(int nameCode,
int typeCode,
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.
- attribute in interface Receiver
nameCode
- The name of the attribute, as held in the name pooltypeCode
- The type of the attribute, as held in the name poolproperties
- Bit significant value. The following bits are defined:
comment
public void comment(CharSequence chars,
int locationId,
int properties)
throws XPathException
Output a comment
- comment in interface Receiver
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.
- namespace in interface Receiver
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.
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.
- startContent in interface Receiver
startElement
public void startElement(int nameCode,
int typeCode,
int locationId,
int properties)
throws XPathException
Notify the start of an element
- startElement in interface Receiver
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.properties
- properties of the element node
