Conductor Script Commands
Appendix A Conductor Script Commands 279
CreateFilter
The
CreateFilter
command creates a filter for events posted on the current
engine object.
CreateFilter time_interval filter_expression
The
CreateFilter
command is only available when an engine is current. Use the
FindEngine
Script command to set the current engine.
The
CreateFilter
command assigns a filter ID to the new filter.
The filter_expression argument provides the criteria used to filter the universe of
events posted by the engine. These events include all state changes to sessions,
process instances, and activities, as well as changes in process attributes. The filter
expression uses a number of comparison operators to specify three filter expression
elements. The three elements—type, object class, and object instance—and the
operators are described below:
