  • Method Details

    • getOperatorFunctionDefinition

      FunctionDefinition getOperatorFunctionDefinition()
      gets the FunctionDefinition for the function that will be evaluated at rule execution time. Note that the backing FunctionTypeService must be locally available to the application at execution time, as execution objects in KRMS can not be obtained over the service bus. The FunctionDefinition returned by this method must have a return type of java.lang.Boolean, and must have either one or two FunctionParameterDefinitions.
      Returns:
      a FunctionDefinition with a return type of Boolean

    • validateOperandClasses

      List<RemotableAttributeError> validateOperandClasses(String lhsClassName, String rhsClassName)
      Validates that the given operand classes are acceptable for the custom function.

      Note that the attribute name in returned errors will be ignored.

      If only a single operand has been specified, then rhsClassName will be null.

      Parameters:
      lhsClassName - the class name for the left hand side operand
      rhsClassName - the class name for the right hand side operand
      Returns:
      A list of errors, or an empty list if no errors are found
