 /**
  * A counting Bloom filter using an array to track counts for each enabled bit
  * index.
- * 
+ *
  * <p>Any operation that results in negative counts or integer overflow of
  * counts will mark this filter as invalid. This transition is not reversible.
  * The operation is completed in full, no exception is raised and the state is
  * set to invalid. This allows the counts for the filter immediately prior to the
  * operation that created the invalid state to be recovered. See the documentation
  * in {@link #isValid()} for details.

+ *
  * <p>All the operations in the filter assume the counts are currently valid,
  * for example cardinality or contains operations. Behaviour of an invalid
  * filter is undefined. It will no longer function identically to a standard
  * Bloom filter that is the merge of all the Bloom filters that have been added
  * to and not later subtracted from the counting Bloom filter.

  * <p>The maximum supported number of items that can be stored in the filter is
  * limited by the maximum array size combined with the {@link Shape}. For
  * example an implementation using a {@link Shape} with a false-positive
