Example

@orderedTerminal("isSorted")
class IsSortedOperator<T> extends TyneqOrderedTerminalOperator<T, boolean> {
    process(): boolean {
        const items = [...this.source];
        for (let i = 1; i < items.length; i++) {
            if (this.source.comparer(items[i - 1], items[i]) > 0) return false;
        }
        return true;
    }
}
