Duncan Jones commented on TEXT-84: ---------------------------------- bq. WDYT? I suppose you could run some tests to prove your assumptions around performance? Supposing it existed, how would you propose to use ThreadLocalRandom with RandomStringGenerator? bq. Is there a value in "conditional immutability"? In the Pair example, I could imagine some limited usefulness (perhaps when composing Pairs into another object). Less so with RandomStringGenerator. > RandomStringGenerator claims to be immutable, but isn't > ------------------------------------------------------- > > Key: TEXT-84 > URL: https://issues.apache.org/jira/browse/TEXT-84 > Project: Commons Text > Issue Type: Bug > Affects Versions: 1.1 > Reporter: Duncan Jones > > {{RandomStringGenerator}} claims to be immutable in the Javadocs, however it > accepts a {{TextRandomProvider}} object through the builder pattern. This > object may altered by external code, thus breaking the immutability claim of > our generator. > A possible solution is to adjust the documentation for {{TextRandomProvider}} > and require implementations to be immutable. Alternatively, we can relax the > documentation in {{RandomStringGenerator}} to remove the immutability claim > or state that the mutability is linked to the mutability of the random source > (when provided). > I think we will have to do the latter, since the former would forbid callers > from supplying a {{UniformRandomProvider}} instance as suggested in the > documentation. Thoughts welcome. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
