In TIBCO Object Service Broker, you use conditional processing to determine whether a given expression is true or false. Based on the result, you control which action statements in the rule are subsequently executed.
Conditions are logical expressions evaluated sequentially for their truth value. The sequencing of actions following this evaluation is regulated by the Y/N quadrant and the action numbers that are specified for the rules statements. If one of the conditions is satisfied, the actions corresponding to it are executed and no further conditions are evaluated. If no conditions are given, all the numbered action statements in the body of the rule are executed.
The following example shows the condition segment containing an expression and the action segment showing the first action to take place based on the values determined by the Y/N quadrant:
To add conditions, type an I into the line command field of the condition section and press Enter to insert a line. Add each condition, ending each one with a semicolon(;).
This part of the rule also contains the Y/N quadrant, which contains values that associate conditions with actions. The Rule Editor manages the Y/N quadrant; you cannot edit it.
