Class LocalDate

java.lang.Object

org.apache.cassandra.cql3.functions.types.LocalDate

public final class LocalDate
extends java.lang.Object

A date with no time components, no time zone, in the ISO 8601 calendar.

Note that ISO 8601 has a number of differences with the default gregorian calendar used in Java:

• it uses a proleptic gregorian calendar, meaning that it's gregorian indefinitely back in the past (there is no gregorian change);
• there is a year 0.

This class implements these differences, so that year/month/day fields match exactly the ones in CQL string literals.

Since:

2.2
