public interface ExternalObjectModel
This interface is designed to enable advanced applications to implement and register new object model implementations that Saxon can then use without change. Although it is intended for external use, it cannot at this stage be considered part of the stable Saxon Public API. In particular, it is likely that the interface will grow by the addition of new methods.
Modifier and Type | Method and Description |
---|---|
Value |
convertObjectToXPathValue(java.lang.Object object,
Configuration config)
Convert a Java object to an XPath value.
|
java.lang.Object |
convertToNodeList(SequenceExtent extent)
Convert a sequence of values to a NODELIST, as defined in the JAXP XPath API spec.
|
java.lang.Object |
convertXPathValueToObject(Value value,
java.lang.Class 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.
|
boolean |
isRecognizedNode(java.lang.Object object)
Test whether this object model recognizes a given node as one of its own.
|
boolean |
isRecognizedNodeClass(java.lang.Class nodeClass)
Test whether this object model recognizes a given class as representing a
node in that object model.
|
boolean |
isRecognizedNodeListClass(java.lang.Class nodeClass)
Test whether this object model recognizes a given class as representing a
list of nodes in that object model.
|
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.
|
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)
