An implementation of PartiQL for the JVM written in Kotlin.

There is a newer version: 1.0.0-perf.1

package org.partiql.lang.util

/**
 * Converts [this] [Long] to a [Int], throwing an exception in case the value is outside the range of an [Int].
 *
 * This is needed because Kotlin's default [Long.toInt()] returns `-1` instead of throwing an exception.
 */

    if (this !in Int.MIN_VALUE..Int.MAX_VALUE) {
        throw IllegalStateException("Long value is not within Int.MIN_VALUE..Int.MAX_VALUE")
    } else {
        this.toInt()
    }
