Uses of VarHandle in jdk.incubator.foreign

Methods in jdk.incubator.foreign that return VarHandle

Modifier and Type	Method	Description
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 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.filterValue(VarHandle target, MethodHandle filterToTarget, MethodHandle filterFromTarget)	Adapts a target var handle by pre-processing incoming and outgoing values using a pair of 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(ValueLayout layout)	Creates a memory access var handle from given value layout.
default VarHandle	MemoryLayout.varHandle(MemoryLayout.PathElement... elements)	Creates a memory access var handle that can be used to dereference memory at the layout selected by a given layout path, where the path is considered rooted in this layout.
