A class that provides support for bit_vectors that represent a balanced parentheses sequence. Implementation was proposed by Kunihiko Sadakane in the paper "The Ultimate Balanced Parentheses" (Technical Report 2008).

class sdsl::bp_support_sada< SmlBlkSize, MedBlkDeg, RankSupport, SelectSupport >
A class that provides support for bit_vectors that represent a balanced parentheses sequence. Implementation was proposed by Kunihiko Sadakane in the paper "The Ultimate Balanced Parentheses" (Technical Report 2008).
This data structure supports the following methods on a bit_vector b that represents a balanced parentheses sequence:
- rank
- select
- excess
- find_open
- find_close
- enclose
- rr_enclose
An opening parenthesis in the balanced parentheses sequence is represented by a 1 in the bit_vector and a closing parenthesis by a 0.
This class could be parametrized by four parameters:
- SmlBlkSize is the size of the small blocks. Denoted as "s" in Sadakane's paper.
- MedBlkDeg is the number of small blocks that a medium block contains. Denoted as "l" in Sadakane's paper.
- RankSupport is a class which support the rank operation on bit_vectors.
- SelectSupport is a class which support the select operation on bit_vectors.
