Method Detail

fromValue

public <V extends org.msgpack.value.Value,O> O fromValue(V v)
                                                        throws MessagePackValueMapperException

Description copied from interface: MessagePackValueMapper

Create Java object out of its MessagePack representation.

Specified by:

fromValue in interface MessagePackValueMapper

Type Parameters:

V - source MessagePack entity type

O - target object type

Parameters:

v - MessagePack entity

Returns:

Java object

Throws:

MessagePackValueMapperException - if the corresponding conversion cannot be performed

fromValue

public <V extends org.msgpack.value.Value,O> O fromValue(V v,
