Description copied from interface: ProcessorDataManager

Lookup a value from a cached code table. If the code table is not loaded, it will be loaded on the first query. Code tables should be cached based on a combination of the codeTableName, returnElementName, and keyElementName. If the table is not loaded, a request will be made and the method should throw a BlockedException.

Specified by:

lookupCodeValue in interface ProcessorDataManager

Throws:

BlockedException

TeiidComponentException

TeiidProcessingException
