SUMMARY

This article defines and describes Action and Decision elements.

SYMPTOMS

N/A

RESOLUTION

Unlike configurable action or decision elements, a standard action or decision element is designed more as a one-off as they satisfy an application-specific purpose. As a result, standard action and decision elements do not require configurations.

There are many situations where programming effort is required to perform some task specific to an application. Since the task is very specialized, pre-existing reusable elements are too general to perform the effort. Additionally, building a configurable element for this purpose would be overkill since there is little chance it would be needed anywhere but in this application. The developer would use a standard action or decision element to perform just this task. If the task is applicable to multiple situations, the developer most likely would put in the extra effort to construct a configurable, reusable element.

Audium provides a means of defining standard decision elements without programming by writing an XML document directly within Audium Builder for Studio. This format should be investigated when desiring simple or moderately complex standard decision elements, falling back on the programming API should the XML format prove insufficient. The XML format for standard decision elements is described later in this chapter.
