Class SaplingDocument

java.lang.Object

net.sf.saxon.sapling.SaplingNode

net.sf.saxon.sapling.SaplingDocument

All Implemented Interfaces:

javax.xml.transform.Source, ActiveSource

public class SaplingDocument
extends SaplingNode
implements ActiveSource

A document node in a sapling tree. A document node may have a sequence of children, each of which is an element, text, comment, or processing-instruction node. A document node has an optional base URI.

Like all sapling nodes, a SaplingDocument is immutable. All operations such as adding children deliver a new document node. A sapling node generally exists only transiently during tree construction; to make use of the constructed tree, it will usually be converted to a regular tree when construction is complete, using toXdmNode(Processor) or toNodeInfo(Configuration).

SaplingDocument implements Source, and a sapling document can therefore be supplied in most Saxon interfaces that expect a Source. However, third-party software that expects a Source as input is unlikely to recognize this class, unless explicitly stated to the contrary.

Constructor Summary

Constructors

Constructor and Description
SaplingDocument() Create a sapling document node with no children and no base URI
SaplingDocument(java.lang.String baseUri) Create a sapling document node with no children, having a specified base URI

Method Summary

Modifier and Type	Method and Description
void	deliver(Receiver receiver, ParseOptions options) Send a sequence of events representing this node to a supplied Receiver
int	getNodeKind() Get the kind of node (document, element, text, comment, or processing instruction)
java.lang.String	getSystemId() Get the system identifier.
void	send(Processor processor, Destination destination) Send the document to an arbitrary destination
void	serialize(Serializer serializer) Serialize the document
void	setSystemId(java.lang.String systemId) Set the system identifier for this Source.
NodeInfo	toNodeInfo(Configuration config) Convert the sapling document to a regular document, returning the NodeInfo object representing the document node of the resulting tree
XdmNode	toXdmNode(Processor processor) Convert the sapling document to a regular document, returning the XdmNode object representing the document node of the resulting tree
SaplingDocument	withChild(SaplingNode... children) Add a number of child nodes to a document node, returning a new document node with additional children beyond those already present.

Constructor Detail

SaplingDocument

public SaplingDocument()

Create a sapling document node with no children and no base URI

SaplingDocument

public SaplingDocument(java.lang.String baseUri)

Create a sapling document node with no children, having a specified base URI

Parameters:

baseUri - the base URI of the document node

Method Detail

setSystemId

public void setSystemId(java.lang.String systemId)

Set the system identifier for this Source. This method is provided because it is needed to satisfy the Source interface; however it always throws an exception, because SaplingDocument is immutable.

Specified by:

setSystemId in interface javax.xml.transform.Source

Parameters:

systemId - The system identifier as a URL string.

Throws:

java.lang.UnsupportedOperationException - always

getSystemId

public java.lang.String getSystemId()

Get the system identifier. This implementation of the method returns the base URI.

Specified by:

getSystemId in interface javax.xml.transform.Source

Returns:

The base URI of the document.

getNodeKind

public int getNodeKind()

Description copied from class: SaplingNode

Get the kind of node (document, element, text, comment, or processing instruction)

Specified by:

getNodeKind in class SaplingNode

Returns:

the kind of node, for example Type.ELEMENT for an element node.

withChild

public SaplingDocument withChild(SaplingNode... children)

Add a number of child nodes to a document node, returning a new document node with additional children beyond those already present. The target document is not modified, neither are the added children.

Parameters:

children - The nodes to be added as children. The supplied nodes are added in order after any existing children.

Returns:

the new parent document node

Throws:

java.lang.IllegalArgumentException - if any of the nodes supplied as an argument is a document node.

deliver

public void deliver(Receiver receiver,
                    ParseOptions options)
             throws XPathException

Description copied from class: SaplingNode

Send a sequence of events representing this node to a supplied Receiver

Specified by:

deliver in interface ActiveSource

Specified by:

deliver in class SaplingNode

Parameters:

receiver - the receiver to which the events are to be sent

options - parse options (currently ignored)

Throws:

XPathException - if the receiver throws an exception

toNodeInfo

public NodeInfo toNodeInfo(Configuration config)
                    throws XPathException

Convert the sapling document to a regular document, returning the NodeInfo object representing the document node of the resulting tree

Parameters:

config - the Saxon Configuration

Returns:

the document node at the root of the constructed tree. The implementation model for the tree will be the default tree model of the Configuration

Throws:

XPathException - if construction fails; this could happen if constraints have been violated

toXdmNode

public XdmNode toXdmNode(Processor processor)
                  throws SaxonApiException

Convert the sapling document to a regular document, returning the XdmNode object representing the document node of the resulting tree

Parameters:

processor - the s9api Processor object that is to own the resulting tree

Returns:

the document node at the root of the constructed tree. The implementation model for the tree will be the default tree model of the Processor's Configuration

Throws:

SaxonApiException - if construction fails; this could happen if constraints have been violated

serialize

public void serialize(Serializer serializer)
               throws SaxonApiException

Serialize the document

Parameters:

serializer - the serializer to be used; the serialized representation of the node will be written to the serializer's destination.

Throws:

SaxonApiException - if anything goes wrong

send

public void send(Processor processor,
                 Destination destination)
          throws SaxonApiException

Send the document to an arbitrary destination

Parameters:

processor - the s9api processor

destination - the destination to which the document will be copied.

Throws:

SaxonApiException - if anything goes wrong
