= 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. :leveloffset: +1 include::value.adoc[] include::string.adoc[] include::array.adoc[] include::object.adoc[] include::numbers.adoc[] include::init_lists.adoc[] include::nested_access.adoc[] :leveloffset: -1
