Flashback cache

A simple zero-dependencies non-distributed Time to Life in-memory cache.

Motivation

There is a lot of cache solution in market full of capabilities, therefore why another cache system? Basically to have some low-weight short-time cache for medium time consumption operations.

Quick start

(Please read our Javadoc for further information)

1. First of all include the Jar file in your compile and execution classpath. Maven

    <dependency>
        <groupId>org.bytemechanics</groupId>
        <artifactId>flashback-cache</artifactId>
        <version>X.X.X</version>
    </dependency>
   

   Graddle

   dependencies {
    compile 'org.bytemechanics:flashback-cache:X.X.X'
   }
   

2. Allocate the cache service who will store all the cache values, or use the provided singleton

   package mypackage;
   import org.bytemechanics.cache.flashback.service.CacheServiceSingleton;
   public class MyClass{
    private static final CacheServiceSingleton cacheService=CacheServiceSingleton.getInstance();
   }
   

3. Create a new cache
   • Infinite cache

     MyObject myResolvedValue=cacheService.from("my.cache.key",() -> methodRecoverCacheValue());
     

   • TTL cache (will be keep the same value until the next recover after 2 minutes)

     MyObject myResolvedValue=cacheService.from("my.cache.key",2l,ChronoUnit.MINUTES,() -> methodRecoverCacheValue());
