Method Detail

doProcess

protected void doProcess(ExecutionResult result)
                  throws Exception

Description copied from class: AbstractBaseExtractor

Process the execution result as input.

This method will only be called if no execution error occurred. Otherwise the error flags of all data items are automatically set.

This method must apply the attributes from AbstractBaseExtractor.fillNoError(Map) when updating items. This is needed since applying them afterwards would cause two updates on the dataitem and the state would by async to the value itself.

Specified by:

doProcess in class AbstractBaseExtractor

Parameters:

result - the execution result that has to be processes

Throws:

Exception - if anything goes wrong

getFields

protected abstract String[] getFields(ExecutionResult result)

register

public void register(Hive hive,
            FolderItemFactory folderItemFactory)

Specified by:

register in interface Extractor

Overrides:

register in class AbstractBaseExtractor

updateData

protected void updateData(String value,
              int group)

getItemForGroup

protected DataItemInputChained getItemForGroup(int group)
