Description

Declares a data structure for JSON-like structured key-value mapping.

A tree is composed of nodes that can have different types:

• Value (gmx::KeyValueTreeValue) is a generic node that can represent either a scalar value of arbitrary type, or an object or an array.
• Array (gmx::KeyValueTreeArray) is a collection of any number of values (including zero). The values can be of any type and different types can be mixed in the same array.
• Object (gmx::KeyValueTreeObject) is a collection of properties. Each property must have a unique key. Order of properties is preserved, i.e., they can be iterated in the order they were added.
• Property (gmx::KeyValueTreeProperty) is an arbitrary type of value associated with a string key. The root object of a tree is typically an object, but could also be an array. The data structure itself does not enforce any other constraints, but the context in which it is used can limit the allowed scalar types or, e.g., require arrays to have values of uniform type. Also, several operations defined for the structure (string output, comparison, serialization, etc.) only work on a limited set of scalar types, or have limitations with the types of trees they work on (in particular, arrays are currently poorly supported).
