Introduce new filter input stream with replacement facilities
-------------------------------------------------------------
Key: IO-218
URL: https://issues.apache.org/jira/browse/IO-218
Project: Commons IO
Issue Type: Improvement
Components: Filters
Affects Versions: 1.4
Environment: all environments
Reporter: Denis Zhdanov
Fix For: 2.0, 1.4
It seems convenient to have a FilterInputStream that allows to apply predefined
repalcement rules against the read data.
For example we may want to configure the following replacements:
{noformat}
{1, } -> {7, 8}
{1} -> {9}
{3, 2} -> {}
{noformat}
and apply them to the input like
{noformat}
{4, 3, 2, 1, 2, 1, 3}
{noformat}
in order to get a result like
{noformat}
{4, 7, 8, 9, 3}
{noformat}
I created the class that allows to do that and attached it to this ticket. Unit
test class at junit4 format is attached as well.
So, the task is to review the provided classes, consider if it's worth to add
them to commons-io distribution and perform the inclusion in the case of
possible result.
