Public Instance Methods
 Compare | Compares the value given to the one that is in the environmnent hashtable. When the expression engine comes upon a condition, it retrieves the appropriate condition type and calls this method to compare the value of the condition with the current value in the user's environment. The result of the comparison determines whether the condition has been met. NOTE: Any exception thrown from this method will be caught and discarded. If an exception is caught, it will be considered a return value of FALSE. |
| GetTypeID | Each condition type needs a unique identifier. The Identifier is used as a key when storing information needed in the user's environment, and to be able to store and retrieve its list of conditions in the activityspace. The determination of whether a condition is met has two parts: find out the current value, then compare it to the condition's value. The unique identifier will be used to store the current value in the environment hashtable so that it can be easily retrieved later. The expression editor displays its conditions via having an expandable list per condition type. All the condition type lists are stored in the expression editor's activity space, and therefore the editor needs unique identifiers to be able to retrieve each list and display them. |
