Hello,

I am trying to figure out this block of code, but it escapes me.
https://github.com/couchbaselabs/TouchDB-Android/blob/master/TouchDB-...

I am not sure what the regular expression statement is supposed to do.  I
ran it through Regex::Explain the output is https://gist.github.com/4068456.
  public static final String LEGAL_CHARACTERS =
"abcdefghijklmnopqrstuvwxyz0123456789_$()+-/";
  if((name == null) || (name.length() == 0) || Pattern.matches("^" +
LEGAL_CHARACTERS, name) || !Character.isLowerCase(name.charAt(0))) {
            return null;
        }
What value would cause the statement to return true and thus return null
from the method?

Additionally, what name scenario would have slashes to replace with colon?

  name = name.replace('/', ':')

If someone could point me in the right direction I would appreciate it.  I am considering a desktop version, and
I want to write tests for these statements.

Thank you.

Regards,
Brian
