What's the order of operations

What's the order of these operations?

public SortedMap<K, V> prefixMap(K prefix)

public Map.Entry<K, V> select(K key)

Specially I am concerned about the order of prefixMap() method. Does it go over all entries from the beginning to find the matching entries or does it jump to the matching entry and then do a traverse from there?
