The Map class

(No version information available, might only be in Git)

���

A Map is a sequential collection of key-value pairs, almost identical to an array used in a similar context. Keys can be any type, but must be unique. Values are replaced if added to the map using the same key.

Strengths

  • Keys and values can be any type, including objects.
  • Supports array syntax (square brackets).
  • Insertion order is preserved.
  • Performance and memory efficiency is very similar to an array.
  • Automatically frees allocated memory when its size drops low enough.

Weaknesses

  • Can't be converted to an array when objects are used as keys.
