jdk.incubator.foreign.SegmentAllocator

Packages that use SegmentAllocator

Package	Description
jdk.incubator.foreign	Classes to support low-level and efficient foreign memory/function access, directly from Java.

Uses of SegmentAllocator in jdk.incubator.foreign

Methods in jdk.incubator.foreign that return SegmentAllocator

Modifier and Type	Method	Description
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.
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 SegmentAllocator	SegmentAllocator.ofSegment(MemorySegment segment)	Returns a segment allocator which responds to allocation requests by recycling a single segment; that is, each new allocation request will return a new slice starting at the segment offset 0 (alignment constraints are ignored by this allocator).

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

Modifier and Type	Method	Description
MethodHandle	CLinker.downcallHandle(Addressable symbol, SegmentAllocator allocator, MethodType type, FunctionDescriptor function)	Obtain a foreign method handle, with the given type and featuring the given function descriptor, which can be used to call a target foreign function at the given address.
static MemorySegment	CLinker.toCString(String str, SegmentAllocator allocator)	Converts a Java string into a UTF-8 encoded, null-terminated C string, storing the result into a native memory segment allocated using the provided allocator.
MemorySegment	CLinker.VaList.vargAsSegment(MemoryLayout layout, SegmentAllocator allocator)	Reads the next value as a MemorySegment, and advances this va list's position.
