Class JSVirtualMachine

  • All Implemented Interfaces:
    NSObject
    public class JSVirtualMachine
extends NSObject
    [@interface] An instance of JSVirtualMachine represents a single JavaScript "object space" or set of execution resources. Thread safety is supported by locking the virtual machine, with concurrent JavaScript execution supported by allocating separate instances of JSVirtualMachine. A virtual machine may need to run deferred tasks on a run loop, such as garbage collection or resolving WebAssembly compilations. By default, a virtual machine will use the run loop of the thread it was initialized on. Currently, there is no API to change a JSVirtualMachine's run loop once it has been initialized.

        [@methodgroup] Memory Management Notify the JSVirtualMachine of an external object relationship. Allows clients of JSVirtualMachine to make the JavaScript runtime aware of arbitrary external Objective-C object graphs. The runtime can then use this information to retain any JavaScript values that are referenced from somewhere in said object graph. For correct behavior clients must make their external object graphs reachable from within the JavaScript runtime. If an Objective-C object is reachable from within the JavaScript runtime, all managed references transitively reachable from it as recorded using -addManagedReference:withOwner: will be scanned by the garbage collector.
        Parameters:
        object - The object that the owner points to.
        owner - The object that owns the pointed to object.

      • init

      • removeManagedReferenceWithOwner

                                            java.lang.Object owner)
        Notify the JSVirtualMachine that a previous object relationship no longer exists. The JavaScript runtime will continue to scan any references that were reported to it by -addManagedReference:withOwner: until those references are removed.
        Parameters:
        object - The object that was formerly owned.
        owner - The former owner.
