Method Summary

Modifier and Type	Method	Description
ActiveSource	getActiveSource(javax.xml.transform.Source supplied)	Give this ExternalObjectModel the opportunity of recognising a Source object and returning an ActiveSource, which will be used to send an instance of this external model to a supplied Receiver.
Receiver	getDocumentBuilder(javax.xml.transform.Result result)	Test whether this object model recognizes a particular kind of JAXP Result object, and if it does, return a Receiver that builds an instance of this data model from a sequence of events.
java.lang.String	getDocumentClassName()	Get the name of a characteristic class, which, if it can be loaded, indicates that the supporting libraries for this object model implementation are available on the classpath
java.lang.String	getIdentifyingURI()	Get the URI of the external object model as used in the JAXP factory interfaces for obtaining an XPath implementation
static DominoTreeModel	getInstance()
JPConverter	getJPConverter(java.lang.Class sourceClass, Configuration config)	Get a converter from values in the external object model to XPath values.
java.lang.String	getName()	Get a name that identifies the tree model
PJConverter	getNodeListCreator(java.lang.Object node)	Get a converter that converts a sequence of XPath nodes to this model's representation of a node list.
PJConverter	getPJConverter(java.lang.Class<?> targetClass)	Get a converter from XPath values to values in the external object model
int	getSymbolicValue()	Get the integer constant used to identify this tree model in some legacy interfaces
Builder	makeBuilder(PipelineConfiguration pipe)	Make a Builder, which can then be used to construct an instance of this tree model from a stream of events
NodeInfo	unravel(javax.xml.transform.Source source, Configuration config)	Wrap or unwrap a node using this object model to return the corresponding Saxon node.

Method Detail

getInstance

public static DominoTreeModel getInstance()

getDocumentClassName

public java.lang.String getDocumentClassName()

Get the name of a characteristic class, which, if it can be loaded, indicates that the supporting libraries for this object model implementation are available on the classpath

Specified by:

getDocumentClassName in interface ExternalObjectModel

Returns:

by convention (but not necessarily) the class that implements a document node in the relevant external model

getIdentifyingURI

public java.lang.String getIdentifyingURI()

Get the URI of the external object model as used in the JAXP factory interfaces for obtaining an XPath implementation

Specified by:

getIdentifyingURI in interface ExternalObjectModel

Returns:

the URI used to identify this object model in the JAXP XPath factory mechanism.

makeBuilder

public Builder makeBuilder(PipelineConfiguration pipe)

Description copied from class: TreeModel

Make a Builder, which can then be used to construct an instance of this tree model from a stream of events

Specified by:

makeBuilder in class TreeModel

Parameters:

pipe - A PipelineConfiguration, which can be constructed using the method Configuration.makePipelineConfiguration().

Returns:

a newly created Builder

getSymbolicValue

public int getSymbolicValue()

Description copied from class: TreeModel

Get the integer constant used to identify this tree model in some legacy interfaces

Overrides:

getSymbolicValue in class TreeModel

Returns:

an integer constant used to identify the model, for example Builder.TINY_TREE

getName

public java.lang.String getName()

Description copied from class: TreeModel

Get a name that identifies the tree model

Overrides:

getName in class TreeModel

Returns:

an identifying name for the tree model

getActiveSource

public ActiveSource getActiveSource(javax.xml.transform.Source supplied)

Give this ExternalObjectModel the opportunity of recognising a Source object and returning an ActiveSource, which will be used to send an instance of this external model to a supplied Receiver. The default implementation returns null.

Specified by:

getActiveSource in interface ExternalObjectModel

Parameters:

supplied - a supplied Source

Returns:

an ActiveSource object if the source is recognised, or null if not

getDocumentBuilder

public Receiver getDocumentBuilder(javax.xml.transform.Result result)
                            throws XPathException

Test whether this object model recognizes a particular kind of JAXP Result object, and if it does, return a Receiver that builds an instance of this data model from a sequence of events. If the Result is not recognised, return null.

This implementation always returns null (the Domino model is never used for transformation or query results)

Specified by:

getDocumentBuilder in interface ExternalObjectModel

Parameters:

result - a JAXP result object

Returns:

a Receiver that writes to that result, if available; or null otherwise

Throws:

XPathException - if any failure occurs

getPJConverter

public PJConverter getPJConverter(java.lang.Class<?> targetClass)

Get a converter from XPath values to values in the external object model

Specified by:

getPJConverter in interface ExternalObjectModel

Parameters:

targetClass - the required class of the result of the conversion. If this class represents a node or list of nodes in the external object model, the method should return a converter that takes a native node or sequence of nodes as input and returns a node or sequence of nodes in the external object model representation. Otherwise, it should return null.

Returns:

a converter, if the targetClass is recognized as belonging to this object model; otherwise null

getJPConverter

public JPConverter getJPConverter(java.lang.Class sourceClass,
                                  Configuration config)

Get a converter from values in the external object model to XPath values.

Specified by:

getJPConverter in interface ExternalObjectModel

Parameters:

sourceClass - the class (static or dynamic) of values to be converted

config - the Saxon Configuration

Returns:

a converter, if the sourceClass is recognized as belonging to this object model; otherwise null

getNodeListCreator

public PJConverter getNodeListCreator(java.lang.Object node)

Get a converter that converts a sequence of XPath nodes to this model's representation of a node list.

This method is primarily for the benefit of DOM, which uses its own NodeList class to represent collections of nodes. Most other object models use standard Java collection objects such as java.util.List

Specified by:

getNodeListCreator in interface ExternalObjectModel

Parameters:

node - an example of the kind of node used in this model

Returns:

if the model does not recognize this node as one of its own, return null. Otherwise return a PJConverter that takes a list of XPath nodes (represented as NodeInfo objects) and returns a collection of nodes in this object model

unravel

public NodeInfo unravel(javax.xml.transform.Source source,
                        Configuration config)

Wrap or unwrap a node using this object model to return the corresponding Saxon node. If the supplied source does not belong to this object model, return null

Specified by:

unravel in interface ExternalObjectModel

Parameters:

source - a JAXP Source object

config - the Saxon configuration

Returns:

a NodeInfo corresponding to the Source, if this can be constructed; otherwise null
