Methods in jdk.incubator.foreign with parameters of type ResourceScope

Modifier and Type	Method	Description
static MemorySegment	MemorySegment.allocateNative(long bytesSize, long alignmentBytes, ResourceScope scope)	Creates a new confined native memory segment that models a newly allocated block of off-heap memory with given size (in bytes), alignment constraint (in bytes) and resource scope.
static MemorySegment	MemorySegment.allocateNative(long bytesSize, ResourceScope scope)	Creates a new confined native memory segment that models a newly allocated block of off-heap memory with given size (in bytes) and resource scope.
static MemorySegment	MemorySegment.allocateNative(MemoryLayout layout, ResourceScope scope)	Creates a new confined native memory segment that models a newly allocated block of off-heap memory with given layout and resource scope.
static SegmentAllocator	SegmentAllocator.arenaAllocator(long size, ResourceScope scope)	Returns a native arena-based allocator which allocates a single memory segment, of given size (using malloc), and then responds to allocation request by returning different slices of that same segment (until no further allocation is possible).
static SegmentAllocator	SegmentAllocator.arenaAllocator(ResourceScope scope)	Returns a native unbounded arena-based allocator.
MemorySegment	MemoryAddress.asSegment(long bytesSize, Runnable cleanupAction, ResourceScope scope)	Returns a new native memory segment with given size and resource scope (replacing the scope already associated with this address), and whose base address is this address.
MemorySegment	MemoryAddress.asSegment(long bytesSize, ResourceScope scope)	Returns a new native memory segment with given size and resource scope (replacing the scope already associated with this address), and whose base address is this address.
static CLinker.VaList	CLinker.VaList.make(Consumer<CLinker.VaList.Builder> actions, ResourceScope scope)	Constructs a new VaList using a builder (see CLinker.VaList.Builder), associated with a given resource scope.
static MemorySegment	MemorySegment.mapFile(Path path, long bytesOffset, long bytesSize, FileChannel.MapMode mapMode, ResourceScope scope)	Creates a new mapped memory segment that models a memory-mapped region of a file from a given path.
static CLinker.VaList	CLinker.VaList.ofAddress(MemoryAddress address, ResourceScope scope)	Constructs a new VaList instance out of a memory address pointing to an existing C va_list, with given resource scope.
static SegmentAllocator	SegmentAllocator.ofScope(ResourceScope scope)	Returns a native allocator which responds to allocation requests by allocating new segments bound by the given resource scope, using the MemorySegment.allocateNative(long, long, ResourceScope) factory.
static MemorySegment	CLinker.toCString(String str, ResourceScope scope)	Converts a Java string into a UTF-8 encoded, null-terminated C string, storing the result into a native memory segment associated with the provided resource scope.
MemoryAddress	CLinker.upcallStub(MethodHandle target, FunctionDescriptor function, ResourceScope scope)	Allocates a native stub with given scope which can be passed to other foreign functions (as a function pointer); calling such a function pointer from native code will result in the execution of the provided method handle.
MemorySegment	CLinker.VaList.vargAsSegment(MemoryLayout layout, ResourceScope scope)	Reads the next value as a MemorySegment, and advances this va list's position.
