CHAPTER 5: Interapplication Communication with Scripts BridgeTalk message object 187

BridgeTalk message object callbacks

NOTE: The message callbacks are optional, and are not implemented by all message-enabled applications.

type

String The message type, which indicates what type of data the body contains.

Read/write. Default is

ExtendScript.

You can define a type for script-defined data. If you do so, the target application

must have a static

BridgeTalk onReceive method that checks for and processes

that type.

onError

Function A callback function that the target application invokes to return an error

response to the sender. It can send JavaScript run-time errors or exceptions,

or C++ exceptions.

To define error-response behavior, set this to a function definition in the

following form:

bridgeTalkObj.onError = function( errorMsgObject ) {

// error handler defined here

};

The body property of the received message object contains the error

message, and the

headers property contains the error code in its

Error-Code property. See “Messaging error codes” on page 190.

The function returns

undefined.

onReceived

Function A callback function that the target application invokes to confirm that the

message was received. (Note that this is different from the static onReceive

method of the

BridgeTalk class that handles unsolicited messages.)

To define a response to receipt notification, set this to a function definition

in the following form:

bridgeTalkObj.onReceived = function( origMsgObject ) {

// handler defined here

};

The target passes back the original message object, with the body property

set to the empty string.

The function returns

undefined.
