ShiftAddXorSignedStringMap

public ShiftAddXorSignedStringMap(Iterator<? extends CharSequence> iterator,
                                  Object2LongFunction<CharSequence> map)

Deprecated.

Creates a new shift-add-xor signed string map using a given hash map and 32-bit signatures.

Parameters:

iterator - an iterator enumerating a set of strings.

map - a minimal perfect hash for the strings enumerated by iterator; it must support size() and have default return value -1.
