Including additional APT_Operator member functions

You can include calls to specified APT_Operator member functions in your APT_Operator derivation.

The header file, install_directory/Server/PXEngine/incude/apt_framework/operator.h, contains detailed descriptions of the member functions.

addNodeConstraint() or addResourceConstraint(): Specify any operator constraints. The constraints are appended to the existing constraints.

checkWasSuccessful(): Indicate whether the operator has been successfully checked.

declareTransfer(): Specify any data transfers.

getConcreteInputSchema()/getConcreteOutputSchema: Return the concrete schema associated with a data set.

lookupCollectionMethod(): Determine the collection method to be used.

lookupPartitionMethod(): Determine the partitioning method to be used.

reportError(): Specify error-description strings.

setAvailableNodes(): Limit the nodes on which this operator can run. It always clears previous restraints.

setCollectionMethod(): Specify the collection method for a sequential operator.

setKind():: Specify parallel or sequential execution of the operator.

setNodeMap(): Specify how many partitions an operator has and which node each partition runs on.

setPartitionMethod(): Specify the partitioning method for a parallel operator.

setPreservePartitioningFlag() or clearPreservePartitioningFlag(): Modify the preserve-partitioning flag in an output data set.

setRuntimeArgs(): Specify an initialization property list passed to initializeFromArgs_() at run time.

setWorkingDirectory(): Set the working directory before runLocally() is called.
