static VarHandle	MethodHandles.filterCoordinates(VarHandle target, int pos, MethodHandle... filters)	Preview. Adapts a target var handle by pre-processing incoming coordinate values using unary filter functions.
static VarHandle	MethodHandles.filterValue(VarHandle target, MethodHandle filterToTarget, MethodHandle filterFromTarget)	Preview. Adapts a target var handle by pre-processing incoming and outgoing values using a pair of filter functions.

static VarHandle	MethodHandles.insertCoordinates(VarHandle target, int pos, Object... values)	Preview. Provides a target var handle with one or more bound coordinates in advance of the var handle's invocation.
static VarHandle	MethodHandles.memorySegmentViewVarHandle(ValueLayoutPREVIEW layout)	Preview. Creates a var handle object, which can be used to dereference a memory segmentPREVIEW by viewing its contents as a sequence of the provided value layout.
static VarHandle	MethodHandles.permuteCoordinates(VarHandle target, List<Class<?>> newCoordinates, int... reorder)	Preview. Provides a var handle which adapts the coordinate values of the target var handle, by re-arranging them so that the new coordinates match the provided ones.
static VarHandle	ConstantBootstraps.staticFieldVarHandle(MethodHandles.Lookup lookup, String name, Class<VarHandle> type, Class<?> declaringClass, Class<?> fieldType)	Finds a VarHandle for a static field.
VarHandle	MethodHandles.Lookup.unreflectVarHandle(Field f)	Produces a VarHandle giving access to a reflected field f of type T declared in a class of type R.
abstract VarHandle	VarHandle.withInvokeBehavior()	Returns a VarHandle, with access to the same variable(s) as this VarHandle, but whose invocation behavior of access mode methods is adjusted to invoke behavior.
abstract VarHandle	VarHandle.withInvokeExactBehavior()	Returns a VarHandle, with access to the same variable(s) as this VarHandle, but whose invocation behavior of access mode methods is adjusted to invoke-exact behavior.
