BDE 3.12.0 Highlights

bdlde::Crc32c : Utilities for CRC32-C Checksums

The new class bdlde::Crc32c (note the trailing “c”) calculates a cyclic redundancy check value, an unsigned int, based on Castagnoli polynomials. Furthermore, to improve performance, the implementation invokes special-purpose machine instructions when such are provided by the platform.

Users familiar with the existing bdlde::Crc32 class (note no trailing “c”) should be aware of several differences. The two classes:

• Use related but different algorithms. Given the same input, expect different results from the two classes.

• Have different usage paradigms. The new class provides utility methods; the previously existing class was implemented as a value-semantic type.
