public class ReplacementsFinder<T> extends Object implements 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
edit script, replacing individual
insert commands by fewer replacements acting on
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
interface to process the sub-sequences.
public void visitInsertCommand(T object)Add an object to the pending insertions set.
public void visitKeepCommand(T object)Handle a synchronization object.
When a synchronization object is identified, the pending insertions and pending deletions sets are provided to the user handler as subsequences.
public void visitDeleteCommand(T object)Add an object to the pending deletions set.
