Creating Custom Rules
Custom rules allow administrators to implement flexible business logic and process activities by using information from external sources. Activity and customer context is passed to the custom rule in the form of RuleContext object.
Before custom rules can be used in workflows, they must be created and compiled.
Creating Custom Rules
The following must be completed while creating custom rules. Every custom rule must:
-
Extend the CustomRule class.
-
Have a default constructor. This default constructor must invoke the constructor of CustomRule class.
-
Implement the public int applyRule(RuleContext oContext) method.
A sample custom rule looks like:
import com.egain.platform.module.routing.CustomRule;
import com.egain.platform.module.routing.service.RuleContext;
public class TestRule extends CustomRule {
TestRule() {
super();
}
public int applyRule(RuleContext oContext) {
return NO_ERROR;
}
}
Compiling Custom Rules
After the custom rules have been created, they must be compiled to be able to use them in workflows. Consult your system administrator for details.
