I know the philosophical, technical and emotional discussions
about pro and contra using pointers. I know the problems
and the risks about it, but also the possibilities and
necessities. All in all, I think, pointers are one way to
realize solutions. If it is alright under technical aspects
and cost criteria, we need no further discussion.
Pointer with Java™, that is impossible. But now it is possible. A small pure Java™ Windows© library and a Java™ class, that is all you need. With this library you can create variables outside of Java™ and get their addresses in memory back, for further using. You can set and get the variables and use a few functions to get informations about it. The library makes byte, short (integer), integer (long), long (currency), float (single), double and string types available, as soon as arrays, for user defined types. Originally the library was designed for the use with Jabaco. So you find the definitions, especially the method names, near by Visual Basic. And you can do something more: With this library and class it is possible to create an array of bytes, fill the array with opcodes and execute it with the Windows© API command CallWindowProc. This way opens the gate of a lot of CPU instructions, which can not be used otherwise with Java™.
