  • tmodeltype (strValue) - available if type is "objectreference"
  • tmodelname (strValue) - available if type is "objectreference"
  • tmodelver (strValue) - available if type is "objectreference"
  • tmodelid (intValue) - available if type is "objectreference"
  • tclassname (strValue) - available if type is "objectreference"
  • tclassid (intValue) - available if type is "objectreference"
  • tobjname (strValue) - available if type is "objectreference"
  • tobjid (intValue) - available if type is "objectreference"

Details ​

Use GET_INTERREF_COUNT to get the number of references (count).
The argument attrid has to be set to the ID of the attribue. Alternatively the name of an attribute can be specified with attrname. The argument objid has to be set to the ID of the instance.
The accessed reference index has to be passed in the argument index, where 0 means first reference, count-1 last reference.

The return variable tmodeltype is set to the modeltype of the referenced model, tmodelname is set to the name of the referenced model and tmodelver is set to the version of the referenced model.

If the reference is a modelreference, type is set to the string "modelreference". tmodelid contains the ID of the referenced model version. If the reference is invalid the value is -1.

If the reference is an objectreference, type is set to the string "objectreference", tclassname is set to the name of the class of the target object and tobjname is set to the name of the target object.tmodelid contains the ID of the referenced model version. tclassid contains the ID of the referenced class. tobjid contains the ID of the referenced object, but only if the target model is loaded - else tobjid is -1. If the reference is invalid the values of tmodelid, tclassid and tobjid are -1.
