    • Method Detail

      • getDefault

        public static Namespace getDefault()
        get the singleton instance of this namespace.
        Returns:
        the instance.

      • getSupportedParameterTypes

        public Class<?>[][] getSupportedParameterTypes()
        Description copied from class: Namespace
        Get the supported parameter types for IDs created via subsequent calls to Namespace.createInstance(Object[]). Callers may use this method to determine the available parameter types, and then create and pass in conforming Object arrays to to Namespace.createInstance(Object[]).

        An empty two-dimensional array (new Class[0][0]) is the default returned by this abstract superclass. This means that the Object [] passed to Namespace.createInstance(Object[]) will be ignored.

        Subsclasses should override this method to specify the parameters that they will accept in calls to Namespace.createInstance(Object[]). The rows of the returned Class array are the acceptable types for a given invocation of createInstance.

        Consider the following example: 

         public Class[][] getSupportedParameterTypes() {
        return new Class[][] { { String.class }, { String.class, String.class } };
 }
        The above means that there are two acceptable values for the Object [] passed into Namespace.createInstance(Object[]): 1) a single String, and 2) two Strings. These would therefore be acceptable as input to createInstance: 
                ID newID1 = namespace.createInstance(new Object[] { "Hello" });
        ID newID2 = namespace.createInstance(new Object[] { "Hello", "There"}};
        Overrides:
        getSupportedParameterTypes in class Namespace
        Returns:
        Class [][] an array of class []s. Rows of the returned two-dimensional array define the acceptable parameter types for a single call to Namespace.createInstance(Object[]). If zero-length Class arrays are returned (i.e. Class[0][0]), then Object [] parameters to Namespace.createInstance(Object[]) will be ignored.
