Interface Summary

Interface	Description
AbstractCursor.Getter	Gets a value from a particular field of the current record of this cursor.
ArrayImpl.Factory	Factory that can create a ResultSet or Array based on a stream of values.
Cursor	Interface to an iteration that is similar to, and can easily support, a JDBC ResultSet, but is simpler to implement.
Cursor.Accessor	Accessor of a column value.
DateTimeUtils.OffsetDateTimeHandler	Deals with values of java.time.OffsetDateTime without introducing a compile-time dependency (because OffsetDateTime is only JDK 8 and higher).
StructImpl.Factory	Factory that can create a result set based on a list of values.
