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

initCipher

protected abstract void initCipher()

interceptRecord

protected final Record interceptRecord(Record record)
                                throws Throwable

Description copied from class: ProxyReader

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

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

• Return the record (possibly modified) to pass it downstream.
• Return null to drop the record; the framework reads the next one.
• Throw to fail the pipeline; the framework wraps the throwable in a DataException with .setRecord(record).
• The nested DataReader is opened and closed for you; do not read from it here.
• Do not call DataEndpoint.incrementRecordCount() here.

Overrides:

interceptRecord in class ProxyReader

Throws:

Throwable

encryptField

protected final void encryptField(Field field)
                           throws Throwable

Throws:

Throwable

encryptFieldImpl

protected abstract void encryptFieldImpl(Field field)
                                  throws Throwable

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 ProxyReader
