processData

protected IData processData(IData inputData)

Description copied from class: DataProcessor

Processes the input Data and returns Data for pushing to the next DataSink. Returns null if output Data should not (yet) be pushed downstream.

Specified by:

processData in class DataProcessor

Parameters:

inputData - the Data for processing

Returns:

the processed Data, for sending downstream (if not null)

processDataInfo

protected IDataInfo processDataInfo(IDataInfo inputDataInfo)

Description copied from class: DataProcessor

Informs this DataProcessor of the DataInfo for the Data it will be processing. Typically the subclass will use this information to make any objects or otherwise prepare for calls to processData.

Specified by:

processDataInfo in class DataProcessor

Parameters:

inputDataInfo - the DataInfo of the Data that will be input to this DataProcessor

Returns:

the DataInfo of the Data that will be output by this DataProcessor
