writer - the BSON writer to encode into

value - the value to encode

encoderContext - the encoder context

public UUID decode(BsonReader reader,
 DecoderContext decoderContext)

Description copied from interface: Decoder

Decodes a BSON value from the given reader into an instance of the type parameter T.

Specified by:

decode in interface Decoder<UUID>

Parameters:

reader - the BSON reader

decoderContext - the decoder context

Returns:

an instance of the type parameter T.

getEncoderClass

public Class<UUID> getEncoderClass()

Description copied from interface: Encoder

Returns the Class instance that this encodes. This is necessary because Java does not reify generic types.
