Methods in jdk.incubator.foreign that return VarHandle

Modifier and Type	Method	Description
static VarHandle	MemoryHandles.asAddressVarHandle(VarHandle target)	Adapt an existing var handle into a new var handle whose carrier type is MemoryAddress.
static VarHandle	MemoryHandles.asUnsigned(VarHandle target, Class<?> adaptedType)	Adapts a target var handle by narrowing incoming values and widening outgoing values, to and from the given type, respectively.
static VarHandle	MemoryHandles.collectCoordinates(VarHandle target, int pos, MethodHandle filter)	Adapts a target var handle handle by pre-processing a sub-sequence of its coordinate values with a filter (a method handle).
static VarHandle	MemoryHandles.dropCoordinates(VarHandle target, int pos, Class<?>... valueTypes)	Returns a var handle which will discard some dummy coordinates before delegating to the target var handle.
static VarHandle	MemoryHandles.filterCoordinates(VarHandle target, int pos, MethodHandle... filters)	Adapts a target var handle by pre-processing incoming coordinate values using unary filter functions.

static VarHandle	MemoryHandles.insertCoordinates(VarHandle target, int pos, Object... values)	Provides a target var handle with one or more bound coordinates in advance of the var handle's invocation.
static VarHandle	MemoryHandles.permuteCoordinates(VarHandle target, List<Class<?>> newCoordinates, int... reorder)	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	MemoryHandles.varHandle(Class<?> carrier, long alignmentBytes, ByteOrder byteOrder)	Creates a memory access var handle with the given carrier type, alignment constraint, and byte order.
