java.lang.Objectnet.sf.saxon.dotnet.DotNetObjectModel
public abstract class DotNetObjectModel
The DotNetObjectModel is an ExternalObjectModel that recognizes nodes as defined in the .Net System.Xml namespace, and also recognizes the wrapper objects defined in the Saxon.Api interface. This allows the Saxon.Api objects to be used withing extension functions. This is an abstract class because it is designed to have no references to the classes in Saxon.Api; instead there is a concrete subclass in the Saxon.Api package that has this knowledge.

Method Summary | |
---|---|
Value |
convertObjectToXPathValue(java.lang.Object object,
Configuration config)
Convert a Java object to an XPath value. |
java.lang.Object |
convertXPathValueToObject(Value value,
cli.System.Type targetClass,
XPathContext context)
Convert an XPath value to an object in this object model. |
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 |
getIdentifyingURI()
Get the URI of the external object model as used in the JAXP factory interfaces for obtaining an XPath implementation |
JPConverter |
getJPConverter(java.lang.Class targetClass)
Get a converter from XPath values to values in the external object 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 |
boolean |
isRecognizedNode(java.lang.Object object)
Test whether this object model recognizes a given node as one of its own. |
abstract boolean |
isXdmValue(java.lang.Object object)
Test whether the supplied object is an XDM value as defined in Saxon.Api (implemented this way to avoid a reference to the Saxon.Api package) |
abstract boolean |
isXdmValueType(cli.System.Type type)
Test whether the supplied type is an XDM value type as defined in Saxon.Api (implemented this way to avoid a reference to the Saxon.Api package) |
abstract boolean |
isXmlNodeType(cli.System.Type type)
Test whether the supplied type is a subtype of System.Xml.XmlNode |
boolean |
sendSource(javax.xml.transform.Source source,
Receiver receiver,
PipelineConfiguration pipe)
Test whether this object model recognizes a particular kind of JAXP Source object, and if it does, send the contents of the document to a supplied Receiver, and return true. |
NodeInfo |
unravel(javax.xml.transform.Source source,
Configuration config)
Wrap or unwrap a node using this object model to return the corresponding Saxon node. |
abstract ValueRepresentation |
unwrapXdmValue(java.lang.Object object)
Unwrap an XdmValue |
abstract java.lang.Object |
wrapAsXdmValue(Value value)
Wrap a Value as an XdmValue |
DocumentInfo |
wrapDocument(java.lang.Object node,
java.lang.String baseURI,
Configuration config)
Wrap a document node in the external object model in a document wrapper that implements the Saxon DocumentInfo interface |
NodeInfo |
wrapNode(DocumentInfo document,
java.lang.Object node)
Wrap a node within the external object model in a node wrapper that implements the Saxon VirtualNode interface (which is an extension of NodeInfo) |

ExternalObjectModel
getPJConverter
in interface ExternalObjectModel
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.
public JPConverter getJPConverter(java.lang.Class targetClass)
ExternalObjectModel
getJPConverter
in interface ExternalObjectModel
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
an object of this class as input and returns a node or sequence of nodes in the
native Saxon representation. Otherwise, it should return null.
