Method Detail

createInstance

public ID createInstance(java.lang.Object[] parameters)
                  throws IDCreateException

Creates an instance of an RPCD. The parameters must contain specific information.

Specified by:

createInstance in class Namespace

Parameters:

parameters - a collection of attributes to call the right constructor on RpcId.

Returns:

an instance of RpcId. Will not be null.

Throws:

IDCreateException - if construction fails

getSupportedParameterTypes

public java.lang.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.

getScheme

public java.lang.String getScheme()

Description copied from class: Namespace

Get the primary scheme associated with this namespace. Subclasses must provide an implementation that returns a non-null scheme identifier. Note that the returned scheme should not contain the Namespace.SCHEME_SEPARATOR (\":\").

Specified by:

getScheme in class Namespace

Returns:

a String scheme identifier. Must not be null.
