The Panama MemorySegment and Linker APIs have undergone significant enhancements in recent Java versions, particularly from Java 17 onward. These changes aim to improve the efficiency and usability of memory access and native linking in Java applications. Key updates include the introduction of new methods for better memory management, increased safety checks, and extended interoperability features with native code.
// Example code for creating a MemorySegment and linking to a native function
MemorySegment segment = MemorySegment.allocateNative(1024);
MemoryAddress address = segment.address();
// Load a native library
Linker linker = Linker.nativeLinker();
SymbolLookup lookup = linker.defaultLookup();
MethodHandle nativeFunction = lookup.find("nativeFunction").orElseThrow();
// Invoke the native function
nativeFunction.invoke(address);
