Use the Change Firing Parameter window to edit an existing firing parameter. The firing parameters contain values passed from the trigger point in the application to the Java rule implementor at run time. You can alter the parameters coming from the application before passing them to the Java rule implementor. Typically, these parameters are left unaltered.
To change a firing parameter, enter a field description, select an appropriate option, and click Change. The parameter is changed and the window remains open to specify additional parameters. When you finish specifying initialization parameters, click Close.
The following fields and options are available in this window:
Use the Description field to type a description of the firing parameter. There are three types of firing parameters that can be specified.
Use the Specify a type and value option to specify a constant value to pass to the Java rule implementor.
Use the Get value from method call option to call the specified method on the target object.
Use the Get value from trigger point firing parameters option to pass a specific value from the firing parameters that were specified on the trigger method in the application. An index to the original firing parameter must be specified. This index starts with 0; thus, specify the value 0 to pass the first firing parameter.
