Method Detail

serialize

public RawExceptionMessage serialize(Throwable exception,
                                     Collection<MessageProtocol> accept)

Description copied from interface: ExceptionSerializer

Serialize the given exception to an exception message.

The raw exception message consists of an error code, a message protocol, and a message entity to send across the wire.

The exception serializer may attempt to match one of the protocols passed into the accept parameter.

Specified by:

serialize in interface ExceptionSerializer

Parameters:

exception - The exception to serialize.

accept - The accepted protocols.

Returns:

The raw exception message.

deserialize

public Throwable deserialize(RawExceptionMessage message)

Description copied from interface: ExceptionSerializer

Deserialize an exception message into an exception.

The exception serializer should make a best effort attempt at deserializing the message, but should not expect the message to be in any particular format. If it cannot deserialize the message, it should return a generic exception, it should not itself throw an exception.

Specified by:

deserialize in interface ExceptionSerializer

Parameters:

message - The message to deserialize.

Returns:

The deserialized exception.
