![]() ![]() It's easy to analyse, easy to make it try more/less often and easy to debug. I disagree that the if(!try()) model is good because it's not a logical structure - it doesn't really match the conceptual idea.Īs I highlighted in my other post I think private static final int MAX_RETRIES Intermittent error handling is more complex than OP is giving enough info on. Maybe you should be thinking backoff algorithms or rate-limiting. You certainly can't drop in an infinite loop, but immediately retrying might not save much either. We know we're in a screwed up situation.Īs soon as you get this kind of scenario you have to start thinking about mean time between error, about the error case, whether it's random or based on burst traffic or whatever. Not much has changed so there's no real chance it will ever work. ![]() If it fails more than twice in a row, it will likely never work.If it can fail once, it can probably fail twice in a row.Learn Programming Java Help ← Seek help here Learn Java Java Conference Videos Java TIL Java Examples JavaFX Oracle JVM LanguagesĬlojure Scala Groovy ColdFusion Kotlin Want to practice your coding?ĭailyProgrammer ProgrammingPrompts ProgramBattles List of useful Frameworks / Libraries / Software If you have any questions, please do not hesitate to ask them!

The result of this is I still get the context of the original error, even though it was thrown at the top.Īnother option might be to return a custom NullObject or a UnknownProperty object and compare against that before deciding to trip the catch(), but as you can re-throw errors anyway, and if you're fully in control of the overall structure, I think this is a neat way round the issue of not being able to continue try/catches.Īn old question, but one I had in the past when coming away from VBA scipts to php, where you could us "GoTo" to re-enter a loop "On Error" with a "Resume" and away it went still processing the function. if we get here, $result was valid, or ignored Throw($result) // throw the original error if the result is an error, choose what to do with it this function will pass back a value, or a TemplateExecption if invalid Then, in the calling code, I can decide whether to throw this returned error, causing the try() to catch(), or just continue: // process the template If the user attempts to access a property that doesn't exist on the data, I return the error from deep within the processing function, rather than throwing it. ![]() I needed to do this with a templating framework I'm writing. Another angle on this is returning an Exception, NOT throwing one, from the processing code. ![]()
