From: SpinSPJ: a novel NMR scripting system to implement artificial intelligence and advanced applications
Execution workflow of the proposed SpinSPJ scripting system. The arrows denote the execution flow of script statements in each components. Firstly, by importing the module spinspj, the scripting system installs an importer hook, which defines how to find (“find_module()”) and load (“load_module()”) the module spinspj. Secondly, the fields and methods of module spinspj are wrapped as PyJField and PyJMethod, which enable the Java based fields and methods being called as a conventional CPython style through the JNI
