Modifier and Type	Method	Description
java.io.Reader	create(java.io.Reader input)	Wraps the given Reader with a CharFilter.
void	inform(ResourceLoader loader)	Initializes this component with the provided ResourceLoader (used for loading classes, files, etc).
java.io.Reader	normalize(java.io.Reader input)	Normalize the specified input Reader While the default implementation returns input unchanged, char filters that should be applied at normalization time can delegate to create method.
