cas clj

(cas db e a v-old v-new)

cas-failure clj macro

(cas-failure subtype detail-str data)

(cas-failure subtype detail-str data cause)

Records this raise-site under :eva.cas/<subtype> in eva.error/eva-error-form, and expands into the equivalent of:

   (error (str "<subtype-generic-str>: " detail-str)
          :eva.cas/<subtype>
          cause)

The following map shows, for each subtype, what keywords are required in the data map, and what the generic portion of the string will be:

{:failed-comparison {:required #{:e :expected :found :a}, :generic-str "Comparison failed for CAS"}, :ambiguous-target {:required #{:e :expected :a}, :generic-str "Cannot CAS on an attribute with :db.cardinality/many"}}

raise-cas-failure clj macro

(raise-cas-failure subtype detail-str data)

(raise-cas-failure subtype detail-str data cause)

Records this raise-site under :eva.cas/<subtype> in eva.error/eva-error-form and expands into:

   (raise :eva.cas/<subtype>
          (str "<subtype-generic-str>: " detail-str)
          data
          cause)

The following map shows, for each subtype, what keywords are required in the data map, and what the generic portion of the string will be:

{:failed-comparison {:required #{:e :expected :found :a}, :generic-str "Comparison failed for CAS"}, :ambiguous-target {:required #{:e :expected :a}, :generic-str "Cannot CAS on an attribute with :db.cardinality/many"}}

retract-entity clj
