    Class Reader<Type>

    Represents an instance used to read unknown type of data.

    Here is an example of custom Reader class used to read binary strings:

    class BinaryStringReader extends Reader {

      constructor(binaryString) {
        super();
        this.binaryString = binaryString;
      }

      init() {
        super.init();
        this.size = this.binaryString.length;
      }

      readUint8Array(offset, length) {
        const result = new Uint8Array(length);
        for (let indexCharacter = 0; indexCharacter < length; indexCharacter++) {
          result[indexCharacter] = this.binaryString.charCodeAt(indexCharacter + offset) & 0xFF;
        }
        return result;
      }
    }
