makeConfiguration
-
getConfiguration
Get the Configuration object -
isObjectModelSupported
Test whether a given object model is supported. Returns true if the object model is the Saxon object model, DOM, JDOM, or XOM- Specified by:
isObjectModelSupported
in classXPathFactory
- Parameters:
model
- The URI identifying the object model.- Returns:
- true if the object model is one of
NamespaceConstant.OBJECT_MODEL_SAXON
,XPathConstants.DOM_OBJECT_MODEL
,NamespaceConstant.OBJECT_MODEL_JDOM
, orNamespaceConstant.OBJECT_MODEL_XOM
, orNamespaceConstant.OBJECT_MODEL_DOM4J
-
setFeature
Set a feature of this XPath implementation. The only features currently recognized are:-
XMLConstants.FEATURE_SECURE_PROCESSING
-
FeatureKeys.SCHEMA_VALIDATION
: requests schema validation of source documents. The property is rejected if the configuration is not schema-aware.
- Specified by:
setFeature
in classXPathFactory
- Parameters:
feature
- a URI identifying the featureb
- true to set the feature on, false to set it off- Throws:
XPathFactoryConfigurationException
- if the feature name is not recognized
-
-
getFeature
Get a feature of this XPath implementation. The only features currently recognized are:-
XMLConstants.FEATURE_SECURE_PROCESSING
-
FeatureKeys.SCHEMA_VALIDATION
: requests schema validation of source documents.
- Specified by:
getFeature
in classXPathFactory
- Parameters:
feature
- a URI identifying the feature- Returns:
- true if the feature is on, false if it is off
- Throws:
XPathFactoryConfigurationException
- if the feature name is not recognized
-
-
setXPathVariableResolver
Set a resolver for XPath variables. This will be used to obtain the value of any variable referenced in an XPath expression. The variable resolver must be allocated before the expression is compiled, but it will only be called when the expression is evaluated.- Specified by:
setXPathVariableResolver
in classXPathFactory
- Parameters:
xPathVariableResolver
- The object used to resolve references to variables.
-
setXPathFunctionResolver
Set a resolver for XPath functions. This will be used to obtain an implementation of any external function referenced in an XPath expression. This is not required for system functions, Saxon extension functions, constructor functions named after types, or extension functions bound using a namespace that maps to a Java class.- Specified by:
setXPathFunctionResolver
in classXPathFactory
- Parameters:
xPathFunctionResolver
- The object used to resolve references to external functions.
-
newXPath
Create an XPath evaluator- Specified by:
newXPath
in classXPathFactory
- Returns:
- an XPath object, which can be used to compile and execute XPath expressions.
