extends DynamicConstantDesc<? extends MemoryLayout>>MemoryLayout.describeConstable()GroupLayout.memberLayouts()Returns the member layouts associated with this group.FunctionDescriptor.returnLayout()Returns the return layout (if any) associated with this function descriptor.Methods in jdk.incubator.foreign with parameters of type MemoryLayoutModifier and TypeMethodDescriptiondefault MemorySegmentSegmentAllocator.allocate(MemoryLayout layout) Allocate a memory segment with given layout.default MemorySegmentSegmentAllocator.allocateArray(MemoryLayout elementLayout, long count) Allocate a memory segment with given element layout and size.static MemorySegmentMemorySegment.allocateNative(MemoryLayout layout, ResourceScope scope) Creates a new native memory segment that models a newly allocated block of off-heap memory with given layout and resource scope.FunctionDescriptor.appendArgumentLayouts(MemoryLayout... addedLayouts) Create a new function descriptor with the given argument layouts appended to the argument layout array of this function descriptor.FunctionDescriptor.asVariadic(MemoryLayout... variadicLayouts) Obtain a specialized variadic function descriptor, by appending given variadic layouts to this function descriptor argument layouts.FunctionDescriptor.changeReturnLayout(MemoryLayout newReturn) Create a new function descriptor with the given memory layout as the new return layout.MemorySegment.elements(MemoryLayout elementLayout) Returns a sequentialStreamover disjoint slices (whose size matches that of the specified layout) in this segment.FunctionDescriptor.insertArgumentLayouts(int index, MemoryLayout... addedLayouts) Create a new function descriptor with the given argument layouts inserted at the given index, into the argument layout array of this function descriptor.static FunctionDescriptorFunctionDescriptor.of(MemoryLayout resLayout, MemoryLayout... argLayouts) Create a function descriptor with given return and argument layouts.static FunctionDescriptorFunctionDescriptor.ofVoid(MemoryLayout... argLayouts) Create a function descriptor with given argument layouts and no return layout.static SequenceLayoutMemoryLayout.sequenceLayout(long elementCount, MemoryLayout elementLayout) Create a new sequence layout with given element layout and element count.static SequenceLayoutMemoryLayout.sequenceLayout(MemoryLayout elementLayout) Create a new sequence layout, with unbounded element count and given element layout.voidVaList.skip(MemoryLayout... layouts) Skips a number of elements with the given memory layouts, and advances this variable argument list's position.MemorySegment.spliterator(MemoryLayout elementLayout) Returns a spliterator for this memory segment.static GroupLayoutMemoryLayout.structLayout(MemoryLayout... elements) Create a new struct group layout with given member layouts.static GroupLayoutMemoryLayout.unionLayout(MemoryLayout... elements) Create a new union group layout with given member layouts.Method parameters in jdk.incubator.foreign with type arguments of type MemoryLayoutModifier and TypeMethodDescriptiondefault MemoryLayoutMemoryLayout.map(UnaryOperator<MemoryLayout> op, MemoryLayout.PathElement... elements) Creates a transformed copy of this layout where a selected layout, from a path rooted in this layout, is replaced with the result of applying the given operation.
