interceptRecord

protected Record interceptRecord(Record record)
                          throws Throwable

Description copied from class: ProxyWriter

Overridden by subclasses to transform, drop, or observe a record on its way through this proxy.

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

• Return the record (possibly modified) to forward it to the nested DataWriter.
• Return null to drop the record; the framework will not write it downstream.
• Throw to fail the pipeline; the framework wraps the throwable in a DataException with .setRecord(record).
• The nested DataWriter is opened and closed for you; do not write to it here.
• Do not call DataEndpoint.incrementRecordCount() here.

Overrides:

interceptRecord in class ProxyWriter

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 ProxyWriter
