Class ModuleLayer.Controller

  • Enclosing class:

    public static final class ModuleLayer.Controller
    extends Object
    Controls a module layer. The static methods defined by ModuleLayer to create module layers return a Controller that can be used to control modules in the layer.

    Unless otherwise specified, passing a null argument to a method in this class causes a NullPointerException to be thrown.

    API Note:
    Care should be taken with Controller objects, they should never be shared with untrusted code.

      • addReads

        public ModuleLayer.Controller addReads​(Module source,
                                               Module target)
        Updates module source in the layer to read module target. This method is a no-op if source already reads target.
        Implementation Note:
        Read edges added by this method are weak and do not prevent target from being GC'ed when source is strongly reachable.
        source - The source module
        target - The target module to read
        This controller
        IllegalArgumentException - If source is not in the module layer
