Unpacker.beginArray

Deserializes the type-information of container.

These methods don't deserialize contents. You need to call unpack method to deserialize contents at your own risk.

// serialized data is [1, "Hi!"];
int num;
unpacker.beginArray(2).unpack(num);  // num is 1

// other operation

string str;
unpacker.unpack(str);  // str is "Hi!"
