public class AMFDataItem
extends AMFData

AMFDataItem: class for marshalling data between Wowza Pro server and Flash client. The type wraps native Java data types.

• DATA_TYPE_NUMBER = int, long, short, double, float
• DATA_TYPE_STRING = String
• DATA_TYPE_BOOLEAN = boolean
• DATA_TYPE_DATE = Date
• DATA_TYPE_NULL = 'null'

Create Native Java Types

AMFDataItem amfDataString = new AMFDataItem("here is my string"); // String
AMFDataItem amfDataLong = new AMFDataItem(1234L); // long
AMFDataItem amfDataDouble = new AMFDataItem(1.234); // double
AMFDataItem amfDataBoolean = new AMFDataItem(true); // boolean
AMFDataItem amfDataNull = new AMFDataItem(); // null

Get Native Java Types

                      amfDataString.toString():"";
