4.1.2 Implementing a Rule Criteria Handler

For the newly created RuleCriteria mentioned in step above , create a RuleCriteriaHandler implementation. This class implements the interface named com.ofss.digx.app.approval.service.rulecriteria.handler.IRuleCriteriaHandler

Override the methods

  • addRuleCriteriaRelationships : This method returns the list of RuleRuleCriteriaRelationshipDTO to be added as a part of the newly created RuleCriteria to the rule being created for the TaskType to which the customized task belongs.
  • getRuleCriteriaMultiplierForRule: returns a multiplier (datatype :double) which gives precedence to a rule over other rule in case both the rules are applicable for a particular instance of a transaction.

Note:

While implementing Rule Criteria Handler make sure that it is implemented in a way that it does not impact existing Tasks in the system belonging to the TaskType against which it is added.
