Constructor Detail

MessageMarshallerDelegate

public MessageMarshallerDelegate(SerializationContextImpl ctx,
                                 MessageMarshaller<T> marshaller,
                                 Descriptor messageDescriptor)

Method Detail

getMarshaller

public MessageMarshaller<T> getMarshaller()

Description copied from interface: BaseMarshallerDelegate

Gets the wrapped marshaller.

Specified by:

getMarshaller in interface BaseMarshallerDelegate<T>

Returns:

the wrapped marshaller instance

getMessageDescriptor

public Descriptor getMessageDescriptor()

getFieldDescriptors

public FieldDescriptor[] getFieldDescriptors()

getFieldByName

public FieldDescriptor getFieldByName(java.lang.String fieldName)
                               throws java.io.IOException

Throws:

java.io.IOException

marshall

public void marshall(FieldDescriptor fieldDescriptor,
                     T message,
                     ProtoStreamWriterImpl writer,
                     RawProtoStreamWriter out)
              throws java.io.IOException

Description copied from interface: BaseMarshallerDelegate

Marshalls an object.

Specified by:

marshall in interface BaseMarshallerDelegate<T>

Parameters:

fieldDescriptor - the FieldDescriptor of the field being marshalled or null if this is a top-level object

message - the value being marshalled (cannot be null)

writer - the ProtoStreamWriterImpl instance to use/re-use, if the specific marshaller type needs one; can be null in which case the delegate has to create a ProtoStreamWriterImpl instance itself based on the out parameter

out - the Protobuf tag output stream (cannot be null)

Throws:

java.io.IOException - if marshalling fails for some reason

unmarshall

public T unmarshall(FieldDescriptor fieldDescriptor,
                    ProtoStreamReaderImpl reader,
                    RawProtoStreamReader in)
             throws java.io.IOException

Description copied from interface: BaseMarshallerDelegate

Unmarshalls an object.

Specified by:

unmarshall in interface BaseMarshallerDelegate<T>

Parameters:

fieldDescriptor - the FieldDescriptor of the field being unmarshalled or null if this is a top-level object

reader - the ProtoStreamReaderImpl instance to use/re-use, if the specific marshaller type needs one; can be null in which case the delegate has to create a ProtoStreamReaderImpl instance itself based on the in parameter

in - the Protobuf tag input stream (cannot be null)

Throws:

java.io.IOException - if unmarshalling fails for some reason
