[jira] [Created] (TEXT-38) Fluent API in {{RandomStringBuilder}}

Gilles created TEXT-38:
--------------------------

             Summary: Fluent API in {{RandomStringBuilder}}
                 Key: TEXT-38
                 URL: https://issues.apache.org/jira/browse/TEXT-38
             Project: Commons Text
          Issue Type: Improvement
            Reporter: Gilles
             Fix For: 1.0


It can be construed as potentially dangerous to let user code change any of the settings of the builder, as other parts of the code could be using a reference to the same instance.

In Commons Math, where the fluent API pattern was applied, a new builder (immutable) instance would be created.  For example, see [this class|https://git1-us-west.apache.org/repos/asf?p=commons-math.git;a=blob;f=src/main/java/org/apache/commons/math4/fitting/SimpleCurveFitter.java;h=54f6cbfe1e003cec74f2b0e71efc1b13000a5525;hb=HEAD].
