MasterDetailListProcessor

public abstract class AbstractMasterDetailListProcessor<T extends Context>
extends AbstractMasterDetailProcessor<T>

A convenience Processor implementation for storing all MasterDetailRecord generated form the parsed input into a list. A typical use case of this class will be:

 ObjectRowListProcessor detailProcessor = new ObjectRowListProcessor();
 MasterDetailListProcessor masterRowProcessor = new MasterDetailListProcessor(detailProcessor) {
      protected boolean isMasterRecord(String[] row, ParsingContext context) {
          return "Total".equals(row[0]);
      }
 };

 parserSettings.setRowProcessor(masterRowProcessor);

 List<MasterDetailRecord> rows = masterRowProcessor.getRecords();

Constructor Detail

AbstractMasterDetailListProcessor

public AbstractMasterDetailListProcessor(RowPlacement rowPlacement,
                                         AbstractObjectListProcessor detailProcessor)

Creates a MasterDetailListProcessor

Parameters:

rowPlacement - indication whether the master records are placed in relation its detail records in the input.

 Master record (Totals)       Master record (Totals)
  above detail records         under detail records

    Totals | 100                 Item   | 60
    Item   | 60                  Item   | 40
    Item   | 40                  Totals | 100
 

detailProcessor - the ObjectRowListProcessor that processes detail rows.

AbstractMasterDetailListProcessor

public AbstractMasterDetailListProcessor(AbstractObjectListProcessor detailProcessor)

Creates a MasterDetailListProcessor assuming master records are positioned above its detail records in the input.

Parameters:

detailProcessor - the ObjectRowListProcessor that processes detail rows.

Method Detail

masterDetailRecordProcessed

protected void masterDetailRecordProcessed(MasterDetailRecord record,
                                           T context)

Stores the generated MasterDetailRecord with the set of associated parsed records into a list.

Specified by:

masterDetailRecordProcessed in class AbstractMasterDetailProcessor<T extends Context>

Parameters:

record - MasterDetailRecord generated with a set of associated records extracted by the parser

context - A contextual object with information and controls over the current state of the parsing process

See Also:

MasterDetailRecord

processEnded

public void processEnded(T context)

Description copied from interface: Processor

This method will by invoked by the parser once, after the parsing process stopped and all resources were closed.

It will always be called by the parser: in case of errors, if the end of the input us reached, or if the user stopped the process manually using Context.stop().

Specified by:

processEnded in interface Processor<T extends Context>

Overrides:

processEnded in class AbstractMasterDetailProcessor<T extends Context>

Parameters:

context - A contextual object with information and controls over the state of the parsing process

getRecords

public List<MasterDetailRecord> getRecords()

Returns the list of generated MasterDetailRecords at the end of the parsing process.

Returns:

the list of generated MasterDetailRecords at the end of the parsing process.

getHeaders

public String[] getHeaders()

Returns the record headers. This can be either the headers defined in CommonSettings.getHeaders() or the headers parsed in the file when CommonSettings.getHeaders() equals true

Returns:

the headers of all records parsed.
