jdk.incubator.foreign.MemoryAddress

Packages that use MemoryAddress

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

Uses of MemoryAddress in jdk.incubator.foreign

Fields in jdk.incubator.foreign declared as MemoryAddress

Modifier and Type	Field	Description
static final MemoryAddress	MemoryAddress.NULL	The native memory address instance modelling the NULL address, associated with the global resource scope.

Methods in jdk.incubator.foreign that return MemoryAddress

Modifier and Type	Method	Description
MemoryAddress	MemoryAddress.addOffset(long offset)	Creates a new memory address with given offset (in bytes), which might be negative, from current one.
MemoryAddress	Addressable.address()	Map this object into a MemoryAddress instance.
MemoryAddress	CLinker.VaList.address()	Returns the memory address of the C va_list associated with this instance.
default MemoryAddress	MemoryAddress.address()
MemoryAddress	MemorySegment.address()	The base memory address associated with this memory segment.
static MemoryAddress	CLinker.allocateMemory(long size)	Allocates memory of given size using malloc.
static MemoryAddress	MemoryAccess.getAddress(MemorySegment segment)	Reads a memory address from given segment, with byte order set to ByteOrder.nativeOrder().
static MemoryAddress	MemoryAccess.getAddressAtIndex(MemorySegment segment, long index)	Reads a memory address from given segment and element index, with byte order set to ByteOrder.nativeOrder().
static MemoryAddress	MemoryAccess.getAddressAtOffset(MemorySegment segment, long offset)	Reads a memory address from given segment and offset, with byte order set to ByteOrder.nativeOrder().
static MemoryAddress	MemoryAddress.ofLong(long value)	Obtain a native memory address instance from given long address.
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.
MemoryAddress	CLinker.VaList.vargAsAddress(MemoryLayout layout)	Reads the next value as a MemoryAddress and advances this va list's position.

Methods in jdk.incubator.foreign that return types with arguments of type MemoryAddress

Modifier and Type	Method	Description
Optional<MemoryAddress>	SymbolLookup.lookup(String name)	Looks up a symbol with given name in this lookup.

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

Modifier and Type	Method	Description
default MemorySegment	MemorySegment.asSlice(MemoryAddress newBase)	Obtains a new memory segment view whose base address is the given address, and whose new size is computed by subtracting the address offset relative to this segment (see segmentOffset(MemorySegment)) from this segment size.
default MemorySegment	MemorySegment.asSlice(MemoryAddress newBase, long newSize)	Obtains a new memory segment view whose base address is the given address, and whose new size is specified by the given argument.
static void	CLinker.freeMemory(MemoryAddress addr)	Frees the memory pointed by the given memory address.
static CLinker.VaList	CLinker.VaList.ofAddress(MemoryAddress address)	Constructs a new VaList instance out of a memory address pointing to an existing C va_list, backed by the global resource scope.
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 String	CLinker.toJavaString(MemoryAddress addr)	Converts a UTF-8 encoded, null-terminated C string stored at given address into a Java string.
