A CopyInformee is an agent that receives extra information while a tree is being copied.
Factory class to create a ProxyReceiver which filters events on a push pipeline
LocationProvider: this interface represents an object that provides the location of elements in a source document or instructions in a stylesheet or query.
Receiver: This interface represents a recipient of XML tree-walking (push) events.
A SourceLocationProvider is a
The abstract Builder class is responsible for taking a stream of SAX events and constructing a Document tree.
A BuilderMonitor can be inserted into a pipeline immediately in front of a Builder.
The CommentStripper class is a filter that removes all comments and processing instructions.
This class is used for generating complex content, that is, the content of an element or document node.
A ContentHandlerProxy is a Receiver that converts events into the form expected by an underlying SAX2 ContentHandler.
Create a TraceListener that will collect information about the current location in the source document.
Implementation of Locator, used to supply location information to the ContentHandler.
An implementation of the JAXP Source class that supplies a document in the form of a stream of push events sent to a Receiver
IDFilter is a ProxyReceiver that extracts the subtree of a document rooted at the element with a given ID value.
A Receiver that can be inserted into an event pipeline to copy location information.
This class is a filter that passes all Receiver events through unchanged, except that it changes namecodes to allow for the source and the destination using different NamePools.
NamespaceReducer is a ProxyReceiver responsible for removing duplicate namespace declarations.
This receiver is inserted into the output pipeline whenever on-empty is used (XSLT 3.0) on a literal result element, on xsl:element, or on xsl:copy when processing elements.
This class sits in a receiver (push) pipeline and maintains the current path.
The PIGrabber class is a Receiver that looks for xml-stylesheet processing instructions and tests whether they match specified criteria; for those that do, it creates an InputSource object referring to the relevant stylesheet
A PipelineConfiguration sets options that apply to all the operations in a pipeline.
A ProxyReceiver is an Receiver that filters data before passing it to another underlying Receiver.
ReceiverOptions defines a set of constants, which can be used in calls to methods on the Receiver interface.
ReceivingContentHandler is a glue class that provides a standard SAX ContentHandler interface to a Saxon Receiver.
Sender is a helper class that sends events to a Receiver from any kind of Source object
Copies a sequence, supplied as a SequenceIterator, to a push pipeline, represented by a SequenceReceiver
Implement the "sequence normalization" logic as defined in the XSLT 3.0/XQuery 3.0 serialization spec.
This outputter is used when writing a sequence of atomic values and nodes, that is, when xsl:variable is used with content and an "as" attribute.
SequenceReceiver: this extension of the Receiver interface is used when processing a sequence constructor.
This outputter is used when writing a sequence of atomic values and nodes, for example, when xsl:variable is used with content and an "as" attribute.
A Sink is an Receiver that discards all information passed to it
StartTagBuffer is a ProxyReceiver that buffers attributes and namespace events within a start tag.
This class implements the XmlStreamWriter interface, translating the events into Saxon Receiver events.
The RuleBasedStripper class performs whitespace stripping according to the rules of the xsl:strip-space and xsl:preserve-space instructions.
TeeOutputter: a SequenceReceiver that duplicates received events to two different destinations
A filter that can be inserted into a Receiver pipeline to trace the events that pass through.
TransformerReceiver is similar in concept to the JAXP TransformerHandler, except that it implements Saxon's Receiver interface rather than the standard SAX2 interface.
A Transmitter is a source of events sent to a Receiver.
A TreeReceiver acts as a bridge between a SequenceReceiver, which can receive events for constructing any kind of sequence, and an ordinary Receiver, which only handles events relating to the building of trees.
A filter on the push pipeline that performs type checking, both of the item type and the cardinality.
Exception indicating that an attempt was made to copy namespace-sensitive content without copying its associated namespaces
Exception indicating that an attribute or namespace node has been written when there is no open element to write it to
This package provides classes that feed SAX-like events from one tree to another. Some of these classes are associated with serializing the output of a stylesheet, but there are also classes for building a tree from a stream of events, for stripping whitespace, and so on.
Receiver interface defines a class that accepts a stream of events, with one method
defined for each kind of event. The events are modelled on the design of SAX, but adapted
to the XPath data model and to the use of Saxon's NamePool. Attributes and namespaces are
notified individually after the start of the relevant element. Many of the classes
in this package are implementations of the
The immediate output of node constructors in a query or stylesheet goes to a
This is a subclass of
Receiver that can handle an arbitrary sequence, containing atomic values
as well as nodes. When constructing the content of an element, a
when constructing the content of a node such as a text node or attribute, a
is used instead.
The final destination of the push pipeline is sometimes a serializer, and sometimes a tree builder.
The final serialization classes are subclasses of
Emitter, but some of the serialization work
(such as indentation or application of character maps) is done by other classes on the pipeline. These
are generally constructed by extending the
The Emitter is an abstract implementation of the Receiver interface. As well as supporting the Receiver interface, it provides methods for controlling the destination of serialized output (a Writer or OutputStream) and for setting serialization properties (in a Properties object). In practice nearly all the implementations of Receiver are currently subclasses of Emitter, but this may change in the future.
The package includes emitters for the standard output methods xml, html, and text, and proxy emitters to allow a sequence of filters to be applied to the output.,
ContentHandlerProxy allows events to be converted into standard SAX events and
sent to a SAX2
ContentHandler. Similarly, the class
ProxyReceiver acts as a
ContentHandler, accepting SAX2 events and feeding them into a
Builder is a
Receiver that constructs a tree representation of the
document in memory. There are two subclasses for Saxon's two native tree models. Other classes such as
Stripper and a
NamespaceReducer are used to modify the document by adding
filters to the pipeline.
Saxon's schema validator and serializer are both implemented using this push pipeline model.
The classes that perform
schema validation are part of package:
