LDContext class final

A collection of attributes that can be referenced in flag evaluations and analytics events. A LDContext may contain information about a single context or multiple contexts differentiated by the "kind" attribute.

Besides the kind and key (required), LDContext supports built in attributes (optional to use) and also custom attributes.

For a more complete description of context attributes and how they can be referenced in feature flag rules, see the reference guide on setting user attributes and targeting users.
