Class TTLContext

  • public class TTLContext
extends java.lang.Object
    A context class that manages Time-To-Live (TTL) values using a thread-local variable. This class provides utility methods to execute operations with a specified TTL, supporting both void and return-value operations via functional interfaces.

    Example Usage

    
 // Using doWithTTL with a Consumer to handle TTL value
 TTLContext.doWithTTL(ttl -> {
     System.out.println("Current TTL: " + ttl);
 }, Duration.ofSeconds(30));

 // Using doWithTTL with a Function to handle TTL and return a result
 String result = TTLContext.doWithTTL(ttl -> {
     return "TTL is: " + ttl;
 }, Duration.ofSeconds(60));

 // Setting TTL manually
 TTLContext.setTTL(Duration.ofMinutes(5));
 Duration currentTTL = TTLContext.getTTL();

 // Clearing TTL manually
 TTLContext.clearTTL();
