CHAPTER 5: Interapplication Communication with Scripts BridgeTalk message object 185

BridgeTalk message object

The message object defines the basic communication packet that is sent between applications. Its

properties allow you to specify the receiving application (the

target), the data to send to the target (the

body), and the type of data that is sent. The messaging protocol is extensible; it allows you to define new

types of data for the type property, and to send and receive arbitrary additional information with the

headers property.

BridgeTalk message object constructor

Create a new message object using a simple constructor:

var bt = new BridgeTalk;

Before you send a message to another application, you must set the target property to the receiving

application, and the

body property to the data message (typically a script) you want to send.

ping()

BridgeTalk.ping (specifier, pingRequest)

specifier

A specifier for the target application; see “Application specifiers” on page 191.

pingRequest

An identifying key string for a specific type of return value. One of:

X STATUS: Returns the processing status; see getStatus().

X DIAGNOSTICS: Returns a diagnostic report that includes a list of valid ping keys.

X ECHO_REQUEST: Returns ECHO_RESPONSE for a simple ping request.

Sends a message to another application to determine whether it can be contacted. Returns a string

whose meaning is defined by the ping-request key.

pump()

BridgeTalk.pump ()

Checks all active messaging interfaces for outgoing and incoming messages, and processes them if

there are any.

Returns true if any messages have been processed, false otherwise.

(Most applications have a message processing loop that continually checks the message queues, so

use of this method is rarely required.)
