Class JsonFunctions.StatefulFunction

java.lang.Object

org.apache.calcite.runtime.JsonFunctions.StatefulFunction

Enclosing class:

JsonFunctions

public static class JsonFunctions.StatefulFunction
extends Object

State for JSON_EXISTS, JSON_VALUE, JSON_QUERY.

Marked deterministic so that the code generator instantiates one once per query, not once per row.
