----------------------------------------------------------------

Thanks.
I've already tried these but ended up using this one here - I'm not sure why I didn't use
Swizzle so I'll check that again.

edit:
Now I know why I didn't use it. Their {{ReplaceStringsInputStream}} only defines {{read()}}
but not {{read(byte[])}} and {{read(byte[], int, int)}} so calls to the other methods won't
replace the contents.
But the hint did help anyway because I simply subclassed it and overrode these methods. So
that it's working now.

> 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, 2} -> {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.
