The reason why a cached entry was removed.

Author(s):
Charles Fry
Since:
10.0
public enum RemovalCause {
  
  EXPLICIT {
    @Override
    boolean wasEvicted() {
      return false;
    }
  },

  
  REPLACED {
    @Override
    boolean wasEvicted() {
      return false;
    }
  },

  
The entry was removed automatically because its key or value was garbage-collected. This can occur when using CacheBuilder.weakKeys(), CacheBuilder.weakValues(), or CacheBuilder.softValues().
  COLLECTED {
    @Override
    boolean wasEvicted() {
      return true;
    }
  },

  
  EXPIRED {
    @Override
    boolean wasEvicted() {
      return true;
    }
  },

  
The entry was evicted due to size constraints. This can occur when using CacheBuilder.maximumSize or CacheBuilder.maximumWeight.
  SIZE {
    @Override
    boolean wasEvicted() {
      return true;
    }
  };

  
Returns true if there was an automatic removal due to eviction (the cause is neither EXPLICIT nor REPLACED).
  abstract boolean wasEvicted();
