AppendedVectors class

This may be more trouble than it is worth. This trades some computation time for RAM -- rather than allocate a new array the size of all previous arrays, this just points the correct index to their original array values

Signature

export declare class AppendedVectors<T = any> implements Vector<T> 

Import

import { AppendedVectors } from '@grafana/data';

Constructors
