bool supportsDecoding(string $format) Checks whether the deserializer can decode from given format. Parameters string $format format name Return Value bool

mixed decode(string $data, string $format, array $context = array()) Decodes data. Parameters string $data Data to decode string $format Format name array $context options that decoders have access to. The format parameter specifies which format the data is in; valid values depend on the specific implementation. Authors implementing this interface are encouraged to document which formats they support in a non-inherited phpdoc comment. Return Value mixed Exceptions UnexpectedV
