Description
Utility class to calculate the hash of some data.
We are trying to achieve that the same calls gives the same hash on a 32-bit machine and on a 64-bit machine. Longs can be either 32-bit or 64-bit, so we always convert them to 64 bits. We do not try to convert endianness, it would be too costly.

Constructor.
Member Function Documentation
◆ getHash()
|
inline |
Returns the hash value.
◆ parse()
| uint32_t parse | ( | const char * | hash | ) | const |
Converts the given string to a numeric hash value. The object is not changed. Throws an error if the string does not contain a valid hash.
◆ equals()
| bool equals | ( | const char * | hash | ) | const |
Parses the given hash string, and compares it to the stored hash.
◆ str()
| std::string str | ( | ) | const |
Returns the textual representation (hex string) of the stored hash.
