Class ReplacementsFinder<T>
- Type Parameters:
- T- the type of the input to the visit operations.
- All Implemented Interfaces:
- CommandVisitor<T>
 The comparison of two objects sequences leads to the identification of common
 parts and parts which only belong to the first or to the second sequence. The
 common parts appear in the edit script in the form of keep commands,
 they can be considered as synchronization objects between the two sequences.
 These synchronization objects split the two sequences in synchronized
 sub-sequences. The first sequence can be transformed into the second one by
 replacing each synchronized sub-sequence of the first sequence by the
 corresponding sub-sequence of the second sequence. This is a synthetic way to
 see an edit script, replacing individual
 delete, keep and
 insert commands by fewer replacements acting on
 complete sub-sequences.
 
 This class is devoted to perform this interpretation. It visits an
 edit script (because it implements the
 CommandVisitor interface) and calls a user-supplied
 handler implementing the ReplacementsHandler
 interface to process the sub-sequences.
