Class BigIntListener

java.lang.Object

org.apache.drill.exec.store.easy.json.values.ScalarListener

org.apache.drill.exec.store.easy.json.values.BigIntListener

All Implemented Interfaces:

ValueListener

public class BigIntListener
extends ScalarListener

Listener for JSON integer values. Allows conversion from Boolean, double and string types. (The conversion from double is lossy, but perhaps better than failing the query.) Conversion from Boolean is the usual semantics: true = 1, false = 0. Conversion from string uses the Java integer parsing semantics.
