Added in 1.4.1

Kotlin |Java

public final class Row implements Map

A Map that maps column name to value in a row result from a QueryResultIterator.

Provides convenience methods for converting to internal base types - String, Long, Double, and ByteArray.

session.query("SELECT name,ts,dur FROM slice WHERE name LIKE \"activityStart\"").forEach {
    callback(it.string("name"), it.long("ts"), it.long("dur")
    // or, used as a map:
    //callback(it["name"] as String, it["ts"] as Long, it["dur"] as Long)
}

Nullable variants of each convenience method are also provided.
