Each name is represented as an integer range in a vector of chars. Instead of storing the absolute offset inside this array, we can store only the offset to the previous entry (the string size). By doing this we reduce the number of bytes need to store an offset from 4 to 1 bytes (if we set a maximum string length of 255). This is however slower, since the absolute offset must be computed on each querry by summing up all previous lengths. To limit the performance inpact we only do this for blocks of a certain size (16). |
