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 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.
