NSData

super: Object

This class is reserved and cannot be directly instantiated.

Properties

var length: Int The number of bytes contained by the data object. (read-only)
var position: Int The position used for the Read and Write methods. This proprerty is automatically incremented by all of the Read and Write methods.
var littleEndian: Int The byte order used by the Read and Write methods. If true, values are stored with the least-significant bytes first. The default value is true.
var objectName: String The name of the object.

Methods
