I am new to java functional programming and looking if there is any fancy java 8 feature that I can use for retry logic without much changes to the existing methods in the class:
public class MyClass{
public Pair<Integer, Integer> funA(int paramA, String paramB, int paramC);
public Pair<Integer, String> funB(int paramA);
}
Is it possible to write a wrapper around this class for a generic retry logic that can take any function of this class as input and retry based on the pair key like:
public static T RetryWrapper(Function func)
while(retryCounter < maxRetries){
Pair< Integer, T > result = func.get();
if(result.getKey() > 0)
return result.getValue();
retryCounter++;
}
Any code examples on how to implement and use this would be very helpful.
