Peter Phillips created TEXT-96:
----------------------------------
Summary: Convenience methods needed for RandomStringGenerator
Key: TEXT-96
URL: https://issues.apache.org/jira/browse/TEXT-96
Project: Commons Text
Issue Type: Improvement
Affects Versions: 1.1
Reporter: Peter Phillips
Priority: Minor
{{RandomStringGenerator}} is extremely verbose compared to the deprecated
commons.lang3 {{RandomStringUtils}}.
Previously we could write:
{code:java}
RandomStringUtils.randomNumeric(10)
{code}
to generate a numeric string whereas this now has become:
{code:java}
new RandomStringGenerator.Builder().withinRange('0', '9').build().generate(10)
{code}
although in practice we would then also use static imports too.
The {{randomAlphabetic}} conversion is even more verbose:
{code:java}
new RandomStringGenerator.Builder().withinRange('A', 'z').filteredBy(new
CharacterPredicate() {
@Override
public boolean test(int codePoint) {
return codePoint >= 'a' || codePoint <= 'Z';
}
}).build().generate(10))
{code} and at that point I lost enthusiam with trying to replicate
{{randomAlphanumeric}}.
I don't think the average java developer would understand what a code point is
in the first place so then trying to get our automation testers to use the new
API to implement random alphanumeric character generation would be difficult.
I therefore suggest that commons-text should have a copy of
{{RandomStringUtils}} which can even delegate to {{RandomStringGenerator}} or
alternatively convenience static methods for the common use cases.
