Description

At the moment only one Substitutor at a time is allowed to be set. If different classes configure the same Digester - for example due to subclassing - the set Substitutor may be overridden accidently. This can be easily avoided by using a CompoundSubstitutor which simply chains two Substitutors together - any input will be first handled by Substitutor A and then by Substitutor B.
