getByKey()

AbstractStateOfKeyPtr StateOfKeyHashTable::getByKey

(

keyType

probeKey

)

probe if we have something with the same key as ask

Parameters

probeKey

The key for probing

Returns

the stored AbstractStateOfKey, nullptr if nothing

insert()

void StateOfKeyHashTable::insert

(

AbstractStateOfKeyPtr

ask
