org.aesh.terminal.tty.impl.WinConsoleNative

public final class WinConsoleNative
extends Object

JNI bridge to Windows console API (Kernel32). Replaces JNA for GraalVM native-image compatibility.

This class provides low-level access to Windows console functions via JNI. The native library (aesh-console.dll) is loaded from the system library path or extracted from the JAR at runtime.
