All gists Back to GitHub. The stored data in the Hash table can be retrieved with the help of the key as a reference. This is a common, and fairly valid request, but I would strongly prefer something that modelled the semantics of creating, and applying, an anonymous define on an array instead of an explicit "loop" construct in the language. The HashSet class is based on the model of mathematical sets and provides high-performance set operations similar to accessing the keys of the Dictionary or Hashtable collections.

If the 'rpm_mon_base_pack' key appeared at multiple levels of your hierarchy, then the array returned by hiera_array() would contain the values from the other levels, too -- that's the main purpose of the funciton. So the idea is to abandon create_resources() and use Puppet 5's each function on the hiera_hash just creating a new file within the loop. Use a similar pattern to the example above, but this time we'll pass an entire hash in:. Now that all the setup work is done (see Puppet Test Driven Development: Part 0 - Setup your environment), you can start writing some code.

Iterating the hash like you do slightly increases the chance of collisions (as a hash function is not a random permutation, but an approximation of a random function): It is enough if two different passwords produce the same hash at any of the 100 steps, to produce the same final hash. A for loop repeats a certain section of the code. The Map implementation acts as a bucketed hash table but when buckets get too large in size, they get converted into Tree nodes, each having a similar structure to the nodes of TreeMap. 1 = ARRAYVALUE1 foo.
