= Document Model In this library the following types implement containers used to represent JSON data in memory:

Type

Description

<<ref_array>>

A sequence container of JSON values supporting dynamic size and fast, random

access. The interface and performance characteristics are similar to {std_vector}.

<<ref_object>>

An associative container of key-value pairs with unique keys, where the key

is a string and the mapped type is a JSON value. Search, insertion, and removal have average contant-time complexity. In addition, elements are stored contiguously in memory allowing cache-friendly iteration.

<<ref_string>>

A contiguous range of characters. The library assumes that the contents of

the string holds only valid UTF-8.

<<ref_value>>

A special variant which can hold one of any of the six standard JSON data

types. |===

These containers are explored in-depth in the sections that follow.
