org.geotools.caching.featurecache.FeatureCache.peek()
Looks in the cache for the features within a given envelope.
This function will only look in the cache for the features; it will not look in the underlying datastore.
@param e @return Collection of features found in the cache.

      
      //at this point the cache should contain features from areas 3 & 4 and area 2 should 
      //have been evicted;
      assertEquals(2, cache.peek(e3).size());
      assertEquals(2, cache.peek(e4).size());
      assertEquals(0, cache.peek(e2).size());
      assertEquals(0, cache.peek(e1).size());      
      
      //now lets go back to 1
      fc = cache.getFeatures(f1);
      assertEquals(2, fc.size());
