Handle and extract data from Callbacks


Name Description
LibraryResult Use in-app declared variables to extract and store data. Initialize variables on the cash register side and pass them as arguments to the methods provided by the Java Native Interface (JNI). The JNI then assigns the appropriate value to the variables. The cash register can then access, store and process the information.

The following pages describe extracting data from callbacks:

Handle progress events - JNI

Handle Dynamic Currency Conversion - JNI

Display a screen on a large screen terminal - JNI

Handle the Signature callback - JNI

Handle the Print Receipt callback - JNI
