Method Detail

init

public void init()
          throws DataLoadException

Initialize the feed business object builder to obtain Load item report from dataload.

Specified by:

init in interface BusinessObjectBuilder

Overrides:

init in class TableObjectBuilder

Throws:

DataLoadException - An application exception will be thrown if there was a problem initializing the table object builder.

See Also:

BusinessObjectBuilder.init(), AbstractBusinessObjectBuilder.init()

preProcess

public void preProcess(java.lang.Object inputData)
                throws DataLoadException

This method performs pre-processing of the input data .

This method fetches the feed identifier from the input data and stores it in the instance variable, so it can be retrieved later.

Specified by:

preProcess in interface BusinessObjectBuilder

Overrides:

preProcess in class AbstractBusinessObjectBuilder

Parameters:

inputData - The raw data read in by the data reader. (DataReader)

Throws:

DataLoadException - An application exception should be thrown is there was a problem pre-processing the input data.

postProcess

public void postProcess(java.lang.Object dataObject)
                 throws DataLoadException

This method performs post processing of the data.

This method updates the CMFEEDLOG table (which keeps track of the feed records processed) with the status of the feed load. The subsequent attempts to process feeds read the status from CMFEEDLOG to find out if the feed needs to be re-processed (in case of failures).

Specified by:

postProcess in interface BusinessObjectBuilder

Overrides:

postProcess in class AbstractBusinessObjectBuilder

Parameters:

dataObject - The data object populated with raw data read in by the data reader. (DataReader)

Throws:

DataLoadException - An application exception should be thrown is there was a problem post processing the input data.

endProcess

public void endProcess()
                throws DataLoadException

This method performs post processing of the data after all of the entries in a feed have been processed.

This method updates the feed URL cache, if the entire feed load was successful. Once, a feed URL in the cache is marked as processed, the next time the feed retriever is run, the feed is fetched only if there has been any update to the feed.

Specified by:

endProcess in interface BusinessObjectBuilder

Overrides:

endProcess in class AbstractBusinessObjectBuilder

Throws:

DataLoadException - An application exception will be thrown is there was a problem post processing the loaded data.
