Method Details
- getCompatibleWindowThreashold
  
  public double getCompatibleWindowThreashold()
  
  Returns the % diff that window sizes are allowed to be off in order to match.
- setCompatibleWindowThreashold
  
  public void setCompatibleWindowThreashold(double compatibleWindowThreashold)
- areWindowsCompatible
  
  public boolean areWindowsCompatible(double windowA, double windowB)
  
  Calculates the percentage difference between the windows and sees if it's acceptable according to the set threshold (default 10%). Also returns true if both window sizes are 0.
- getBucketSortFrequency
  
  public long getBucketSortFrequency()
  
  Returns the time, in milliseconds, between potential sorts of the cache buckets. Frequent sorting can help improve the accuracy of the relevancy scores during ejection, but will take more processing time.
- setBucketSortFrequency
  
  public void setBucketSortFrequency(long bucketSortFrequency)
- getMaxCacheSizeBytes
  
  public long getMaxCacheSizeBytes()
  
  The maximum size of the cache, in bytes.
- setMaxCacheSizeBytes
  
  public void setMaxCacheSizeBytes(long value)
