EAI — Redundant "filterCondition" association on EAISubscriptionFilter

  • Key: EAI-83

    Document: UML Profile and Interchange Models for EAI
    Section: (EAISubscriptionOperator)

    An EAISubscriptionFilter is shown in Figure 6-38 as a child of EAIFilter. As such, it already inherits a "filterCondition" association from EAIFilter (see Figure 6-26). Therefore, the additional "filterCondition" association shown in Figure 6-38 is unnecessary (and, indeed, would indicate that the EAISubscriptionFilter has two filter conditions, which does not seem to be the intent).

    Remove the "filterCondition" association from Figure 6-38. Instead, add a constraint that the filterCondition of an EAISubscriptionFilter must be an EAISubscriptionRule.

    (Note also that the multiplicity of the "filterCondition" association shown in Figure 6-38 is "1..n" [sic], while the multiplicity of the "filterCondition" association for EAIFilter is not shown in Figure 6-26, but is implied in the text to be "1..1". If the multiplicity of the EAIFilter association is ultimately made "1..*", then the constraint on EAISubscriptionFilter should be that all the filterConditions are EAISubscriptionRules. If the desire is to have a "1..1" multiplicity on the EAIFilter association, but still to have multiple EAISubscriptionRules for an EAISubscriptionFilter, then an EAICompositeSubscriptionRule needs to be defined to group multiple EAISubscriptionRules into one FCMCondition.)
