I did a grep of "joda" in the java vector codebase. The current reference
to joda includes:
(1) auto-generated reader class under arrow/vector/complex/impl and
arrow/vector/complex/reader
These class currently have API that returns joda classes, e.g.:
NullableTimestampMicroHolderReaderImpl:
// read friendly type
@Override
public LocalDateTime readLocalDateTime() {
if (!isSet()) {
return null;
}
LocalDateTime value = new LocalDateTime(this.holder.value);
return value;
}
UnionReader:
@Override
public LocalDateTime readLocalDateTime() {
return getReaderForIndex(idx()).readLocalDateTime();
}
(2) Timestamp vector classes:
These classes have API that returns joda classes, e.g.:
TimestampMicroVector:
/**
* Same as {@link #get(int)}.
*
* @param index position of element
* @return element at given index
*/
public LocalDateTime getObject(int index) {
if (isSet(index) == 0) {
return null;
} else {
/* value is truncated when converting microseconds to
milliseconds in order to use DateTime type */
final long micros = valueBuffer.getLong(index * TYPE_WIDTH);
final long millis =
java.util.concurrent.TimeUnit.MICROSECONDS.toMillis(micros);
final org.joda.time.LocalDateTime localDateTime = new
org.joda.time.LocalDateTime(millis,
org.joda.time.DateTimeZone.UTC);
return localDateTime;
}
}
(3) arrow/vector/util/DateUtility.java has some functions that uses joda
time
