DataMappingReader

public DataMappingReader(DataReader nestedDataReader,
                         DataMapping dataMapping)

Method Detail

getExpressionContext

public RecordExpressionContext getExpressionContext()

getDataMapping

public DataMapping getDataMapping()

open

public void open()
          throws DataException

Description copied from class: DataEndpoint

Makes this endpoint ready for reading or writing.

Overrides:

open in class IntegrationProxyReader

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 ProxyReader

Throws:

DataException

isLineageSupported

public boolean isLineageSupported()

Overrides:

isLineageSupported in class DataReader

interceptRecord

protected Record interceptRecord(Record record)
                          throws Throwable

Overrides:

interceptRecord in class ProxyReader

Throws:

Throwable

onFailure

protected Record onFailure(Record record,
                           DataException exception,
                           DataMappingResult result)

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 ProxyReader

isSendSkippedToDiscardWriter

public boolean isSendSkippedToDiscardWriter()

setSendSkippedToDiscardWriter

public DataMappingReader setSendSkippedToDiscardWriter(boolean sendSkippedToDiscardWriter)
