bool Key::operator< | ( | Key | key2 | ) | const |
Compares this key with key2.
The result is true if this key precedes key2. The comparison is for byte sequence collating order, taking lengths into account. So if the keys are made up of lower case ASCII letters we get alphabetical ordering.
Now remember that items are added into the B-tree in fastest time when they are preordered by their keys. This is therefore the piece of code that needs to be followed to arrange for the preordering.
This is complicated by the fact that keys have two parts - a value and then a count. We first compare the values, and only if they are equal do we compare the counts.
