Constructors

JSContextGroup(JSContextGroupRef _ref, {bool autoDispose = true})

JSContextGroup.create()

Creates a JavaScript context group. A JSContextGroup associates JavaScript contexts with one another. Contexts in the same group may share and exchange JavaScript objects. Sharing and/or exchanging JavaScript objects between contexts in different groups will produce undefined behavior. When objects from the same context group are used in multiple threads, explicit synchronization is required.
