Class MultiWriter

Method Details

• getWriteStrategy

  public MultiWriter.WriteStrategy getWriteStrategy()

  Returns how records are distributed among the target writers (defaults to REPLICATE_CLONE).

• setWriteStrategy

  public MultiWriter setWriteStrategy(MultiWriter.WriteStrategy writeStrategy)

  Sets how records are distributed among the target writers (defaults to REPLICATE_CLONE).

• add

  public MultiWriter add(DataWriter... sinks)

  Adds target writers; must be called before open().

• getCount

  public int getCount()

  Returns the number of target writers.

• remove

  public MultiWriter remove(DataWriter sink)

• removeAllDataSink

  public MultiWriter removeAllDataSink()

  Removes all target writers; must be called before open().

• get

  public DataEndpoint get(int index)

  Returns the target writer at the given 0-based index.

• open

  public void open() throws DataException

  Description copied from class: DataEndpoint

  Makes this endpoint ready for reading or writing.

  Overrides:

  open in class DataEndpoint

  Throws:

  DataException

• close

  public void close() throws DataException

  Description copied from class: DataEndpoint

  Indicates that this endpoint has finished reading or writing.

  Overrides:

  close in class DataEndpoint

  Throws:

  DataException

• writeImpl

  protected void writeImpl(Record record) throws Throwable

  Description copied from class: DataWriter

  Overridden by subclasses to write the specified record to this DataWriter.

  Contract for subclasses (see also docs/authoring/DataWriter.md):

  • Do not call this method directly — DataWriter.write(Record) is the template method that wraps exceptions, increments the record count, and attaches the offending record to thrown DataExceptions.
  • Do not call DataEndpoint.incrementRecordCount() here; DataWriter.write(Record) already does.
  • Throw raw exceptions; DataWriter.write(Record) wraps them via exception(throwable).setRecord(record).

  Specified by:

  writeImpl in class DataWriter

  Throws:

  Throwable

• addExceptionProperties

  public DataException addExceptionProperties(DataException exception)

  Description copied from class: Endpoint

  Adds this endpoint's current state to a DataException. Since this method is called whenever an exception is thrown, subclasses should override it to add their specific information.

  Overrides:

  addExceptionProperties in class DataWriter
