Class RubyDateTimeParsedElementsQuery<T>

java.lang.Object

org.embulk.util.rubytime.RubyDateTimeParsedElementsQuery<T>

All Implemented Interfaces:

TemporalQuery<Map<T,Object>>

public final class RubyDateTimeParsedElementsQuery<T>
extends Object
implements TemporalQuery<Map<T,Object>>

A query to retrieve a Map of parsed elements.

The Map of parsed elements is analogous to a hash returned from Ruby's Date._strptime like below.

 {:year=>2001, :mon=>2, :mday=>3}
