Disposition Attributes

Disposition attributes instruct the ToolTalk service how to handle messages to your application if an instance of the application is not currently running.

The disposition value specified in the static type definition of a pattern is the default disposition; however, if the message deposition specifies the handler ptype the default disposition value is over-ridden. For example, a message disposition specifies a static type definition for the ptype UWriteIt which includes the message signature Display. This message signature does not match any of the static signatures in the pattern. The ToolTalk service will follow the instructions for the disposition set in the message; for example, if the message disposition is TT_START and the UWriteIt ptype specifies a start string, the ToolTalk service will start an instance of the application if one is not running.
