class LookupTable< EnumType, RecordType, Hasher >

SBuf -> case-insensitive enum lookup table

How to use: enum enum_type { ... }; static const LookupTable<enum_type>::Record initializerTable[] = { {"key1", ENUM_1}, {"key2", ENUM_2}, ... {nullptr, ENUM_INVALID_VALUE} }; LookupTable<enum_type> lookupTableInstance(ENUM_INVALID_VALUE, initializerTable);

then in the code: SBuf s(string_to_lookup); enum_type item = lookupTableInstance.lookup(s); if (item != ENUM_INVALID_VALUE) { // do stuff }
