UPDATE_SINGLE_MODEL ​

UPDATE_SINGLE_MODEL inserts a model into the core's internal structures. It does the same as UPDATE_MODEL_LIST, but just for one model instead of for all models.

Syntax ​

leo-grammar
CC "Core" UPDATE_SINGLE_MODEL model:idValue

#--> RESULT ecode:intValue
CC "Core" UPDATE_SINGLE_MODEL model:idValue

#--> RESULT ecode:intValue

Parameters ​

  • modelid (idValue) -the ID of the model to be updated.

Returns ​

  • ecode (intValue) - Contains the error code or is 0 in case of success.

Details ​

This command is useful for cache implementations, e.g. of a webservice application. If the cache detects that a new model existst, e.g. after having called
CC "DB" GET_ALL_DATES_OF_LAST_CHANGE,
that model cannot be accessed while the core's internal structures are not up-to-date, Updating with UPDATE_SINGLE_MODEL is much faster than UPDATE_MODEL_LIST.
