abstract class ToggleMap extends AnyRef

A collection of Int-typed toggles which can be used to build a form of feature toggles which allow for modifying behavior without changing code.

Expected usage is for code to have toggles passed into their constructors instead of dynamically creating new toggles on every call.

Abstract Value Members

  1. abstract def apply(id: String): Toggle[Int]

    Get a Toggle for this id.

    Get a Toggle for this id.

    The Toggle.isDefined method should return false if the ToggleMap does not know about that Toggle or it is currently not "operating" on that id.

    id

    the identifying name of the Toggle. These should generally be fully qualified names to avoid conflicts between libraries. For example, "com.twitter.finagle.CoolThing".

    Creates a ToggleMap which uses this before that.

    Creates a ToggleMap which uses this before that.

    apply returns a Toggle that uses the Toggle from this if it isDefinedAt for the input, before trying that.

    iterator includes metadata from both self and that, with self's metadata taking precedence on conflicting ids. Note however that if a ToggleMetadata.description is not defined on self, the description from that will be preferred. This is done because many sources of ToggleMaps do not have a description defined and we want to surface that information.
