static_hash_maps: new code generation package to build static hash maps
A static hash map means here a hash maps completely known before compile time. It uses GNAT.Perfect_Hash_Generator to turn string keys into indexes for an array of elements. check-in: 582f564b61 user: nat tags: trunk | |
Changes
Added src/natools-static_hash_maps-s_expressions.adb version [b4bb055a3f].
