load_hashmap: Load Hashmaps

In hashmap: The Faster Hash Map

Description

load_hashmap reads a file created by a call to save_hashmap and returns a Hashmap object.

Usage

load_hashmap(file)

Arguments

file	the name of a file previously created by a call to save_hashmap.

Details

The object returned will contain all of the same key-value pairs that were present in the original Hashmap at the time save_hashmap was called, but they are not guaranteed to be in the same order, due to rehashing.

Value

A Hashmap object on success; an error on failure.
