Class ContextKind

All Implemented Interfaces:
JsonSerializable, Comparable<ContextKind>

public final class ContextKind extends Object implements Comparable<ContextKind>, JsonSerializable
A string identifier provided by the application to describe what kind of entity an LDContext represents.

The type is a simple wrapper for a String. Using a type that is not just String makes it clearer where a context kind is expected or returned in the SDK API, so it cannot be confused with other important strings such as the context key. To convert a literal string to this type, use the factory method of(String).

The meaning of the context kind is completely up to the application. Validation rules are as follows:

  • It may only contain letters, numbers, and the characters ".", "_", and "-".
  • It cannot equal the literal string "kind".
  • For a single-kind context, it cannot equal "multi".

If no kind is specified, the default is "user" (the constant DEFAULT).

For a multi-kind context (see LDContext.createMulti(LDContext...)), the kind of the top-level LDContext is always "multi" (the constant MULTI); there is a specific Kind for each of the contexts contained within it.
