Description
Queries a static field on a class.This is like a global variable as there is only one value for all objects of the class.
Data type is automatically detected by plugin from signature.
If you read an object value, please call Java.Release later for it.
Java is only available if you call Java.Initialize before to load the java runtime.
Supported data types include: void, int, long, boolean, string, double, float, char, byte, object, byte array (for container), char array (using FileMaker text).
For PDF content: If you have a DynaPDF Pro license and DynaPDF functions initialized, this function can add previews for the PDF file on Windows and Linux. For MacOS, we make them with PDFKit.
