getCharTransformer

public static CharTransformer getCharTransformer(String name,
                                                 String config,
                                                 String errorId,
                                                 boolean back)

This method instatiates a CharTransformer by use of reflection.

Parameters:

name - The class name for the CharTransformer to be returned

config - A configuration string for this transformer. At the moment this can be parsed as an integer, or the name of a integer constant of the transformer's class. Likely, other ways to configure a transformer will be available.

errorId - If something goes wrong, an error message is logged, in which this String is used, to clear things up.

back - If true, the Transformer will be wrapped in a InverseCharTransformer, so the transformation will do the inverse thing.

Returns:

A CharTransformer instance or null in case of an error.

getTransformerFactory
