public interface Receiver extends javax.xml.transform.Result
Receiver: This interface represents a recipient of XML tree-walking (push) events. It is based on SAX2's ContentHandler, but adapted to handle additional events. Namespaces and Attributes are handled by separate events following the startElement event. Schema types can be defined for elements and attributes.The Receiver interface is an important internal interface within Saxon, and provides a powerful mechanism for integrating Saxon with other applications. It has been designed with extensibility and stability in mind. However, it should be considered as an interface designed primarily for internal use, and not as a completely stable part of the public Saxon API.
- Since:
- 8.0. Extended in 9.9 to support additional methods with default implementations. Changed in 10.0 to accept all the attributes and namespaces as part of the startElement event (thus eliminating the need for a separate startContent event).

Method Detail
-
setPipelineConfiguration
void setPipelineConfiguration(PipelineConfiguration pipe)
Set the pipeline configuration- Parameters:
pipe
- the pipeline configuration
-
getPipelineConfiguration
PipelineConfiguration getPipelineConfiguration()
Get the pipeline configuration- Returns:
- the pipeline configuration
-
setSystemId
void setSystemId(java.lang.String systemId)
Set the System ID of the tree represented by this event stream- Specified by:
setSystemId
in interfacejavax.xml.transform.Result
- Parameters:
systemId
- the system ID (which is used as the base URI of the nodes if there is no xml:base attribute)
-
open
void open() throws XPathException
Notify the start of the event stream- Throws:
XPathException
- if an error occurs
-
startDocument
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 classReceiverOption
- Throws:
XPathException
- if an error occurs
-
endDocument
void endDocument() throws XPathException
Notify the end of a document node- Throws:
XPathException
- if an error occurs
-
setUnparsedEntity
void setUnparsedEntity(java.lang.String name, java.lang.String systemID, java.lang.String publicID) throws XPathException
Notify an unparsed entity URI.- Parameters:
name
- The name of the unparsed entitysystemID
- The system identifier of the unparsed entitypublicID
- The identifier of the unparsed entity- Throws:
XPathException
- if an error occurs
-
startElement
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 elementnamespaces
- the in-scope namespaces of this element: generally this is all the in-scope namespaces, without relying on inheriting namespaces from parent elementslocation
- an object providing information about the module, line, and column where the node originatedproperties
- bit-significant properties of the element node. If there are no relevant properties, zero is supplied. The definitions of the bits are in classReceiverOption
- Throws:
XPathException
- if an error occurs
-
endElement
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
void characters(java.lang.CharSequence chars, Location location, 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 characterslocation
- 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
-
processingInstruction
void processingInstruction(java.lang.String name, java.lang.CharSequence data, Location location, 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 instructionlocation
- provides information such as line number and system ID.properties
- Additional information about the PI.- Throws:
java.lang.IllegalArgumentException
- if the content is invalid for an XML processing instructionXPathException
- if an error occurs
-
comment
void comment(java.lang.CharSequence content, Location location, int properties) throws XPathException
Notify a comment. Comments are only notified if they are outside the DTD.- Parameters:
content
- The content of the commentlocation
- provides information such as line number and system ID.properties
- Additional information about the comment.- Throws:
java.lang.IllegalArgumentException
- if the content is invalid for an XML commentXPathException
- if an error occurs
-
append
default void append(Item item, Location locationId, int properties) throws XPathException
Append an arbitrary item (node, atomic value, or function) to the output. The default implementation throwsUnsupportedOperationException
.- Parameters:
item
- the item to be appendedlocationId
- the location of the calling instruction, for diagnosticsproperties
- if the item is an element node, this indicates whether its namespaces need to be copied. Values areReceiverOption.ALL_NAMESPACES
; the default (0) means- Throws:
XPathException
- if an error occursjava.lang.UnsupportedOperationException
- if this Receiver does not allow appending of items (at any time, or at this particular point in the sequence of events)
-
append
default void append(Item item) throws XPathException
Append an arbitrary item (node, atomic value, or function) to the output. By default, if the item is an element node, it is copied with all namespaces. The default implementation callsappend(Item, Location, int)
, whose default implementation throwsUnsupportedOperationException
- Parameters:
item
- the item to be appended- Throws:
XPathException
- if the operation fails
-
close
void close() throws XPathException
Notify the end of the event stream- Throws:
XPathException
- if an error occurs
-
usesTypeAnnotations
default boolean usesTypeAnnotations()
Ask whether this Receiver (or the downstream pipeline) makes any use of the type annotations supplied on element and attribute events. The default implementation of this method returns false.- 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)
-
handlesAppend
default boolean handlesAppend()
Ask whether this Receiver can handle arbitrary items in itsappend(net.sf.saxon.om.Item, net.sf.saxon.s9api.Location, int)
andappend(Item, Location, int)
methods. If it cannot, then calling these methods will raise an exception (typically but not necessarily anUnsupportedOperationException
). The default implementation of this method returns false.- Returns:
- true if the Receiver is able to handle items supplied to
its
append(net.sf.saxon.om.Item, net.sf.saxon.s9api.Location, int)
andappend(Item, Location, int)
methods. A receiver that returns true may still reject some kinds of item, for example it may reject function items.
