receives notification of an event. | EventDispatcher | ||
Used by the streaming channels to shut down the streaming connection. | StreamingConnectionHandler | ||
Dispatches an event into the event flow. | EventDispatcher | ||
Checks whether the EventDispatcher object has any listeners registered for a specific type
of event. | EventDispatcher | ||
Indicates whether an object has a specified property defined. | Object | ||
Indicates whether an instance of the Object class is in the prototype chain of the object specified
as the parameter. | Object | ||
Used by the streaming channels to set up the streaming connection if
necessary and issue the open request to the server. | StreamingConnectionHandler | ||
Indicates whether the specified property exists and is enumerable. | Object | ||
Removes a listener from the EventDispatcher object. | EventDispatcher | ||
Sets the availability of a dynamic property for loop operations. | Object | ||
Returns the string representation of this object, formatted according to locale-specific conventions. | Object | ||
Returns the string representation of the specified object. | Object | ||
Returns the primitive value of the specified object. | Object | ||
Checks whether an event listener is registered with this EventDispatcher object or any of

channel | property |
protected var channel:Channel
Language Version: | ActionScript 3.0 |
Product Versions: | BlazeDS 4, Adobe Digital Enterprise Platform Data Services for Java EE 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
The Channel that uses this class.
chunkBuffer | property |
protected var chunkBuffer:ByteArray
Language Version: | ActionScript 3.0 |
Product Versions: | BlazeDS 4, Adobe Digital Enterprise Platform Data Services for Java EE 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Byte buffer used to store the current chunk from the remote endpoint. Once a full chunk has been buffered, a message instance encoded in binary AMF format can be read from the chunk and dispatched.
dataBytesToRead | property |

Product Versions: | BlazeDS 4, Adobe Digital Enterprise Platform Data Services for Java EE 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Counter that keeps track of how many data bytes remain to be read for the current chunk. A sentinal value of -1 indicates an initial state (either waiting for the first chunk or just finished parsing the previous chunk).
dataOffset | property |
protected var dataOffset:int
Language Version: | ActionScript 3.0 |
Product Versions: | BlazeDS 4, Adobe Digital Enterprise Platform Data Services for Java EE 3 |
