Method Details- 
advanceOnCountCreates a new target after a specific number of filters have been added to the current target.- Type Parameters:
- T- Type of BloomFilter.
- Parameters:
- breakAt- the number of filters to merge into each filter in the list.
- Returns:
- A Predicate suitable for the LayerManager extendCheckparameter.
- Throws:
- IllegalArgumentException- if- breakAt <= 0
 
- 
advanceOnPopulatedAdvances the target once a merge has been performed.- Type Parameters:
- T- Type of BloomFilter.
- Returns:
- A Predicate suitable for the LayerManager extendCheckparameter.
 
- 
advanceOnSaturationpublic static <T extends BloomFilter<T>> Predicate<LayerManager<T>> advanceOnSaturation(double maxN) Creates a new target after the current target is saturated. Saturation is defined as theBloom filter estimated N >= maxN.An example usage is advancing on a calculated saturation by calling: ExtendCheck.advanceOnSaturation(shape.estimateMaxN())- Type Parameters:
- T- Type of BloomFilter.
- Parameters:
- maxN- the maximum number of estimated items in the filter.
- Returns:
- A Predicate suitable for the LayerManager extendCheckparameter.
- Throws:
- IllegalArgumentException- if- maxN <= 0
 
- 
neverAdvanceDoes not automatically advance the target. @{code next()} must be called directly to perform the advance.- Type Parameters:
- T- Type of BloomFilter.
- Returns:
- A Predicate suitable for the LayerManager extendCheckparameter.
