Usage

From source file:org.esigate.cache.CacheConfigHelper.java

public static CacheConfig createCacheConfig(Properties properties) {

    // Heuristic caching
    boolean heuristicCachingEnabled = Parameters.HEURISTIC_CACHING_ENABLED.getValue(properties);
    float heuristicCoefficient = Parameters.HEURISTIC_COEFFICIENT.getValue(properties);
    long heuristicDefaultLifetimeSecs = Parameters.HEURISTIC_DEFAULT_LIFETIME_SECS.getValue(properties);
    int maxCacheEntries = Parameters.MAX_CACHE_ENTRIES.getValue(properties);
    long maxObjectSize = Parameters.MAX_OBJECT_SIZE.getValue(properties);

    // Asynchronous revalidation
    int minAsynchronousWorkers = Parameters.MIN_ASYNCHRONOUS_WORKERS.getValue(properties);
    int maxAsynchronousWorkers = Parameters.MAX_ASYNCHRONOUS_WORKERS.getValue(properties);

    int maxUpdateRetries = Parameters.MAX_UPDATE_RETRIES.getValue(properties);
    int revalidationQueueSize = Parameters.REVALIDATION_QUEUE_SIZE.getValue(properties);
