CHAPTER 5: Interapplication Communication with Scripts Messaging framework API reference 179

Messaging framework API reference

This application programming interface (API) defines a communication protocol between

message-enabled applications. These objects are available to all ExtendScript scripts when any of the

applications is loaded.

The messaging protocol is extensible. Although it is primarily designed to send scripts, you can use it to

send other kinds of data.

The messaging API defines the

BridgeTalk class. Static properties and methods of the class provide

access to environmental information relevant for communication between applications. Instantiate the

class to create a

BridgeTalk message object, which encapsulates the message itself. For discussion and

examples, see “

Communicating through messages” on page 170, and the example code provided with the

Adobe ExtendScript SDK.

Example code

The sample code distributed with the Adobe ExtendScript SDK includes these code examples that

specifically demonstrate the use of interapplication messaging:

BridgeTalk class

Static properties and methods of this class provide a way for your script to determine basic messaging

system information before you create any specific message objects. Static methods allow you to check if

an application is installed and is already running, and to launch the application. A callback defined on the

class determines how the application processes incoming messages.

You can access static properties and methods in the

BridgeTalk class, which is available in the global

namespace. For example:

var thisApp = BridgeTalk.appName;

NOTE: You must instantiate the BridgeTalk class to create the BridgeTalk message object, which is used

to send message packets between applications. Dynamic properties and methods can be accessed only in

instances.
