Simplest way to create a VT_UI1 | VT_ARRAY VARIANT from a Java String?

[Markus Karg]

The following code successfully creates a VARIANT from a Java String, where each Java char is one byte element n the SafeArray:

var byteArray = str.getBytes();
var safeArray = OaIdl.SAFEARRAY.createSafeArray(new WTypes.VARTYPE(VT_UI1), byteArray.length))
for (var i = 0; i < byteArray.length; i++)
    safeArray.putElement(byteArray[i], i);
var variant = new VARIANT(safeArray);

I wonder if JNA has some utility that makes it much more convenient and spare some lines (and in particular the custom loop)? 🤔

var safeArray = OaIdl.SAFEARRAY.createSafeArray(new WTypes.VARTYPE(VT_UI1), byteArray.length);

Pointer rawPointer = safeArray.accessData();

rawPointer.write(0, byteArray, 0, byteArray.length);

safeArray.unaccessData();

Wow, thank you Matthias, this is amazing! 🤩
