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
