Class TimeTypeApiOps

Object
org.apache.spark.sql.types.ops.TimeTypeApiOps
All Implemented Interfaces:
Serializable, TypeApiOps
public class TimeTypeApiOps extends Object implements TypeApiOps
Client-side (spark-api) operations for TimeType.

This class implements all TypeApiOps methods for the TIME data type: - String formatting: uses FractionTimeFormatter for consistent output - Row encoding: uses LocalTimeEncoder for java.time.LocalTime

RELATIONSHIP TO TimeTypeOps: TimeTypeOps (in catalyst package) extends this class to inherit client-side operations while adding server-side operations (physical type, literals, etc.).

param: t The TimeType with precision information
