Paul Benedict commented on LANG-508: ------------------------------------ I am preparing to use java.lang.String#format over MessageFormat. > Validate: add message parameter construction via elllipsis notation to speed > up processing > ------------------------------------------------------------------------------------------ > > Key: LANG-508 > URL: https://issues.apache.org/jira/browse/LANG-508 > Project: Commons Lang > Issue Type: Improvement > Affects Versions: 2.4 > Reporter: Mark Struberg > Fix For: 3.0 > > Attachments: LANG-508.patch > > > Currently passing verbose message strings to a log of commons.lang.Validate > functions costs a lot of performance. > A typical usecase currently is: > {noformat} > Validate.isTrue (argInt1.intValue > argInt2.intValue, "param2 actually is " + > argInt2 + " but must larger than param1 " + argInt1 +" !"); > {noformat} > So all the string operations get executed regardless if the validation fails > or not. > This can be made perform much better by moving all the string operations > inside the respective validation function and execute it only if the > validation fails: > {noformat} > Validate.isTrue(argInt1.intValue > argInt2.intValue, "param2 actually is {1} > but must larger than param1 {0} !", argInt1, argInt2); > {noformat} -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
