      • isObjectModelSupported

        public boolean isObjectModelSupported​(java.lang.String objectModel)

        Is specified object model supported by this XPathFactory?

        Specified by:
        isObjectModelSupported in class javax.xml.xpath.XPathFactory
        Parameters:
        objectModel - Specifies the object model which the returned XPathFactory will understand.
        Returns:
        true if XPathFactory supports objectModel, else false.
        Throws:
        java.lang.NullPointerException - If objectModel is null.
        java.lang.IllegalArgumentException - If objectModel.length() == 0.

      • newXPath

        public javax.xml.xpath.XPath newXPath()

        Returns a new XPath object using the underlying object model determined when the factory was instantiated.

        Specified by:
        newXPath in class javax.xml.xpath.XPathFactory
        Returns:
        New XPath

      • setFeature

        public void setFeature​(java.lang.String name,
                       boolean value)
                throws javax.xml.xpath.XPathFactoryConfigurationException

        Set a feature for this XPathFactory and XPaths created by this factory.

        Feature names are fully qualified URIs. Implementations may define their own features. An XPathFactoryConfigurationException is thrown if this XPathFactory or the XPaths it creates cannot support the feature. It is possible for an XPathFactory to expose a feature value but be unable to change its state.

        See XPathFactory for full documentation of specific features.

        Specified by:
        setFeature in class javax.xml.xpath.XPathFactory
        Parameters:
        name - Feature name.
        value - Is feature state true or false.
        Throws:
        javax.xml.xpath.XPathFactoryConfigurationException - if this XPathFactory or the XPaths it creates cannot support this feature.
        java.lang.NullPointerException - if name is null.

      • getFeature

        public boolean getFeature​(java.lang.String name)
                   throws javax.xml.xpath.XPathFactoryConfigurationException

        Get the state of the named feature.

        Feature names are fully qualified URIs. Implementations may define their own features. An XPathFactoryConfigurationException is thrown if this XPathFactory or the XPaths it creates cannot support the feature. It is possible for an XPathFactory to expose a feature value but be unable to change its state.

        Specified by:
        getFeature in class javax.xml.xpath.XPathFactory
        Parameters:
        name - Feature name.
        Returns:
        State of the named feature.
        Throws:
        javax.xml.xpath.XPathFactoryConfigurationException - if this XPathFactory or the XPaths it creates cannot support this feature.
        java.lang.NullPointerException - if name is null.

      • setXPathFunctionResolver

        public void setXPathFunctionResolver​(javax.xml.xpath.XPathFunctionResolver resolver)

        Establish a default function resolver.

        Any XPath objects constructed from this factory will use the specified resolver by default.

        A NullPointerException is thrown if resolver is null.

        Specified by:
        setXPathFunctionResolver in class javax.xml.xpath.XPathFactory
        Parameters:
        resolver - XPath function resolver.
        Throws:
        java.lang.NullPointerException - If resolver is null.

      • setXPathVariableResolver

        public void setXPathVariableResolver​(javax.xml.xpath.XPathVariableResolver resolver)

        Establish a default variable resolver.

        Any XPath objects constructed from this factory will use the specified resolver by default.

        A NullPointerException is thrown if resolver is null.

        Specified by:
        setXPathVariableResolver in class javax.xml.xpath.XPathFactory
        Parameters:
        resolver - Variable resolver.
        Throws:
        java.lang.NullPointerException - If resolver is null.
