JSON

Detailed Description

JSON methods.

Introduction

Contains common methods to create JSON documents, add properties, add either single or list values to properties. String values are escaped to comply with the JSON specification.

Data Structures

A single data structure is used with members for a) the output buffer, and b) the reference data.

The output buffer is represented as a pointer and a length. An additional member is used to record the number of characters that would be needed to complete the creation of a valid JSON response. This can be used by the caller to increase the buffer size if not big enough and call the related methods a subsequent time.

Reference data for the property being added, the values being added, and a collection of strings is also provided.
