ifInt

GetInt() As Integer

Returns the type of event. The following event types are currently defined: transfer complete (1), transfer started (2).

ifString

GetString() As String

Returns the string associated with the event. For transfer-complete AsyncGetToString(), AsyncPostFromString(), and AsyncPostFromFile() requests, this will be the actual response body from the server, truncated to 65,536 characters.

ifSourceIdentity

GetSourceIdentity() As Integer

Returns a unique number that can be matched with the value returned by roUrlTransfer.GetIdentity() to determine where this event originated.

ifUserData

SetUserData(user_data As Object)

Sets the user data that will be returned when events are raised.

GetUserData() As Object

Returns the user data that has previously been set via SetUserData(). It will return Invalid if no data has been set.

ifUrlEvent

GetResponseCode() As Integer

Returns the protocol response code associated with an event. The following codes indicate success:

200: Successful HTTP transfer
226: Successful FTP transfer
0: Successful local file transfer

For unexpected errors, the return value is negative. There are many possible negative errors from the CURL library, but it is often best to look at the text version by calling GetFailureReason().

Here are some potential errors. Not all of them can be generated by a BrightSign player:

The following error codes are generated by the system software, and are outside the range of CURL events:

Status	Name	Description
-10001	ERROR_CANCELLED	The transfer request has been cancelled because the roUrlTransfer instance is out of scope.
-10002	ERROR_EXCEPTION	The callback threw an exception.

GetObject() As Object

Returns the object associated with the event. Currently, this method can only return an object created in response to an roUrlTransfer.AsyncGetToObject request.

GetFailureReason As String

Returns a description of the failure that occurred.

GetSourceIdentity As Integer

Returns a unique number that can be matched with the value returned by roUrlTransfer.GetIdentity() to determine where the event came from.

GetResponseHeaders() As roAssociativeArray

Returns an associative array containing all the headers returned by the server for appropriate protocols (such as HTTP).

GetHash() As String

The hash (digest) of the response body, as specified by the response_pipe{hash:} parameter of the roUrlTransfer.AsyncMethod() method.

GetPrefix() As String

A number of bytes from the start of the response body. The amount of bytes is specified with the response_pipe{prefix_capture:} parameter of the roUrlTransfer.AsyncMethod() method.
