public abstract class AbstractObjectProcessor<T extends Context> extends DefaultConversionProcessor implements Processor<T>
A Processor implementation for converting rows extracted from any implementation of AbstractParser into arrays of objects.

This uses the value conversions provided by Conversion instances.

For each row processed, a sequence of conversions will be executed and stored in an object array, at its original position.

The row with the result of these conversions will then be sent to the rowProcessed(Object[], Context) method, where the user can access it.

    • rowProcessed

      public void rowProcessed(String[] row, T context)
      Executes the sequences of conversions defined using DefaultConversionProcessor.convertFields(Conversion...), DefaultConversionProcessor.convertIndexes(Conversion...) and DefaultConversionProcessor.convertAll(Conversion...), for every field in the given row.

      Each field will be transformed using the Conversion.execute(Object) method.

      In general the conversions will process a String and convert it to some object value (such as booleans, dates, etc).

      Specified by:
      rowProcessed in interface Processor<T extends Context>
      Parameters:
      row - the parsed record with its individual records as extracted from the original input.
      context - the current state of the parsing process.

      Fields that do not have any conversion defined will just be copied to the object array into their original positions.

    • rowProcessed

      public abstract void rowProcessed(Object[] row, T context)
      Invoked by the processor after all values of a valid record have been processed and converted into an Object array.
      Parameters:
      row - object array created with the information extracted by the parser and then converted.
      context - A contextual object with information and controls over the current state of the parsing process

    • processStarted

      public void processStarted(T context)
      Description copied from interface: Processor
      This method will by invoked by the parser once, when it is ready to start processing the input.
      Specified by:
      processStarted in interface Processor<T extends Context>
      Parameters:
      context - A contextual object with information and controls over the current state of the parsing process

    • 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>
      Parameters:
      context - A contextual object with information and controls over the state of the parsing process
