Constructors

new BsonArray(List data) #

Creates a new Object instance.

Object instances have no meaningful state, and are only useful through their identity. An Object instance is equal to itself only.

docs inherited from Object 
BsonArray(this.data);

Properties

List data # 

List data

final int typeByte # 

int get typeByte => _BSON_DATA_ARRAY;

final value # 

get value=>data;
