Method Detail

registerFactory

public static boolean registerFactory(Class sampleClass,
                                      String formatName,
                                      ObjectStreamFactory factory)

Registers factory which reads format named formatName and instantiates streams producing objects of sampleClass class.

Parameters:

sampleClass - class of the objects, produced by the streams instantiated by the factory

formatName - name of the format

factory - instance of the factory

Returns:

true if the factory was successfully registered

unregisterFactory

public static void unregisterFactory(Class sampleClass,
                                     String formatName)

Unregisters a factory which reads format named formatName and instantiates streams producing objects of sampleClass class.

Parameters:

sampleClass - class of the objects, produced by the streams instantiated by the factory

formatName - name of the format

getFactories

public static <T> Map<String,ObjectStreamFactory<T>> getFactories(Class<T> sampleClass)

Returns all factories which produce objects of sampleClass class.

Parameters:

sampleClass - class of the objects, produced by the streams instantiated by the factory

Returns:

formats mapped to factories

getFactory

public static <T> ObjectStreamFactory<T> getFactory(Class<T> sampleClass,
                                                    String formatName)

Returns a factory which reads format named formatName and instantiates streams producing objects of sampleClass class.

Parameters:

sampleClass - class of the objects, produced by the streams instantiated by the factory

formatName - name of the format, if null, assumes OpenNLP format

Returns:

factory instance
