std::size_t	operator() (const OpenMS::DataValue &dv) const noexcept

Detailed Description

Hash function for DataValue.

Hashes based on the value type, value content, and unit information. This ensures consistency with operator== which compares all these fields.

Note

For DOUBLE_VALUE, operator== uses epsilon comparison (fabs < 1e-6), so we round to 6 decimal places before hashing to maintain consistency. For DOUBLE_LIST, we use toString() since list comparison is exact.
