    • isObjectModelSupported

      public boolean isObjectModelSupported​(String objectModel)

      Is specified object model supported by this XPathFactory?

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

    • newXPath

      public XPath newXPath()

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

      Specified by:
      newXPath in class XPathFactory
      Returns:
      New XPath

    • setFeature

      public void setFeature​(String name, boolean value) throws 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 XPathFactory
      Parameters:
      name - Feature name.
      value - Is feature state true or false.
      Throws:
      XPathFactoryConfigurationException - if this XPathFactory or the XPaths it creates cannot support this feature.
      NullPointerException - if name is null.

    • getFeature

      public boolean getFeature​(String name) throws 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 XPathFactory
      Parameters:
      name - Feature name.
      Returns:
      State of the named feature.
      Throws:
      XPathFactoryConfigurationException - if this XPathFactory or the XPaths it creates cannot support this feature.
      NullPointerException - if name is null.

    • setXPathFunctionResolver

      public void setXPathFunctionResolver​(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 XPathFactory
      Parameters:
      resolver - XPath function resolver.
      Throws:
      NullPointerException - If resolver is null.

    • setXPathVariableResolver

      public void setXPathVariableResolver​(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 XPathFactory
      Parameters:
      resolver - Variable resolver.
      Throws:
      NullPointerException - If resolver is null.
