Method Detail

getCodec

public <T> PersistCodec<? super T,? extends T,? extends com.google.protobuf.Message> getCodec(Class<T> type)

Get the codec for this protocol that encodes a particular type (or subclasses) and decodes to that same type (or a subclass).

Parameters:

type - the type to retrieve a codec for

Returns:

an appropriate codec for that type, or null if no suitable codec exists

getCodec

public <S,T> PersistCodec<? super S,? extends T,? extends com.google.protobuf.Message> getCodec(Class<S> upperBound,
                                                                                       Class<T> lowerBound)

Get the codec for this protocol that encodes instances of a particular type (or subclasses) and decodes to another type (or a subclass).

Parameters:

upperBound - the type that the encoder will accept

lowerBound - the type that the decoder will return

Returns:

an appropriate codec for that type, or null if no suitable codec exists

registerCodec

public <S,T extends S> void registerCodec(Class<S> upperTypeBound,
                                 Class<T> lowerTypeBound,
                                 PersistCodec<S,T,?> codec)

Register a codec. Called by individual protocols. Warning: not threadsafe. Callers should ensure that registration is protected by external synchronization.

Parameters:

upperTypeBound - the least-specific type supported by the codec

lowerTypeBound - the most-specific type supported by the codec

codec - the codec itself
