Description copied from class: EncryptionTransformFactory

"Rekeys" an object. This will locate the

Specified by:

rekey in class EncryptionTransformFactory<BasicEncryptionOutputTransform,BasicEncryptionInputTransform>

Throws:

TransformException

DoesNotNeedRekeyException - if the object is already up to date with the latest master key and does not need to be rekeyed.

getOutputTransform

public BasicEncryptionOutputTransform getOutputTransform(java.io.OutputStream streamToEncodeTo,
                                                java.util.Map<java.lang.String,java.lang.String> metadataToEncode)
                                                  throws java.io.IOException

Description copied from class: TransformFactory

Gets an "output" transform for the factory in its current state. This will be used to transform raw data on its way "out" to the server.

Specified by:

getOutputTransform in class TransformFactory<BasicEncryptionOutputTransform,BasicEncryptionInputTransform>

Returns:

a transform that can encode the outbound object stream.

Throws:

java.io.IOException

getOutputTransform

public BasicEncryptionOutputTransform getOutputTransform(java.io.InputStream streamToEncode,
                                                java.util.Map<java.lang.String,java.lang.String> metadataToEncode)

Description copied from class: TransformFactory

Gets an "output" transform for the factory in its current state. This will be used to transform raw data on its way "out" to the server. This version gets an output transform in "pull" mode that uses an input stream to filter the data. This is useful for situations where you need to pump data to an output stream like when using an HTTP output stream.

Specified by:

getOutputTransform in class TransformFactory<BasicEncryptionOutputTransform,BasicEncryptionInputTransform>

Returns:

a transform that can encode the outbound object stream.

Throws:

java.io.IOException

TransformException

getInputTransform

                                                       TransformException

Description copied from class: TransformFactory

Gets the "input" transform for the given class and metadata.

Specified by:

getInputTransform in class TransformFactory<BasicEncryptionOutputTransform,BasicEncryptionInputTransform>

Parameters:

transformConfig - the configuration of the transformClass.

metadata - metadata extracted from the inbound object (used to fine-tune the transformation and/or provide metadata to also be transformed).

Returns:

a transform that can decode the inbound object stream.

Throws:

java.io.IOException

TransformException
