public class ActivityControlImpl

extends BaseImpl

implements SwarmObject, SwarmObjectS, ActivityControlS, ActivityControl

A class that provides an object interface to an activity.. The ActivityControl class specifies an object that can be attached to an activity (regardless of how or where that activity is created) for the purpose of explicitly controlling the execution of actions on that activity's action plan. There is nothing that available through this class that is not already available through the variables or messages available via the activity itself. However, it packages up the main control messages and makes them available to other objects that may need control over an activity, thereby shielding the activity from directly receiving messages from outside objects and saving the user from having to parse the more complex interface to the activity.

Constructor Detail

ActivityControlImpl

public ActivityControlImpl()

ActivityControlImpl

public ActivityControlImpl(Zone aZone)

The create: message creates a new instance of a type with default options. The zone argument specifies the source of storage for the new object. The receiving object of this message is a previously defined type object. The message is declared as a class message (with a + declaration tag) to indicate that the message is accepted only by the type object itself rather than an already created instance of the type (which a - declaration tag otherwise defines). The create: message returns the new object just created. This object is an instance of some class selected to implement the type. The class which a type selects to implement an object may be obtained by the getClass message, but is not otherwise visible to the calling program. A caller never refers to any class name when creating objects using these messages, only to type names, which are automatically published as global constants from any @protocol declaration.
