DecodeException - anything preventing the decoding

fromBuffer

<T> T fromBuffer(Buffer json,
                 Class<T> clazz)
          throws DecodeException

Like fromString(String, Class) but with a json Buffer

Throws:

DecodeException

fromValue

<T> T fromValue(Object json,
                Class<T> toValueType)

Like fromString(String, Class) but with a json Object
