Method Detail

registerRequest

TupleSource registerRequest(CommandContext context,
                            Command command,
                            String modelName,
                            String connectorBindingId,
                            int nodeID,
                            int limit)
                            throws TeiidComponentException,
                                   TeiidProcessingException

Throws:

TeiidComponentException

TeiidProcessingException

lookupCodeValue

Object lookupCodeValue(CommandContext context,
                       String codeTableName,
                       String returnElementName,
                       String keyElementName,
                       Object keyValue)
                       throws BlockedException,
                              TeiidComponentException,
                              TeiidProcessingException

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.

Throws:

BlockedException

TeiidComponentException

TeiidProcessingException

getEventDistributor

EventDistributor getEventDistributor()

getMetadataRepository

MetadataRepository getMetadataRepository()
