Method Detail

decode

public static <T> AutoBean<T> decode(AutoBeanFactory factory,
                                     Class<T> clazz,
                                     Splittable data)

Decode an AutoBeanCodex payload.

Type Parameters:

T - the expected return type

Parameters:

factory - an AutoBeanFactory capable of producing AutoBean<T>

clazz - the expected return type

data - a payload previously generated by encode(AutoBean)

Returns:

an AutoBean containing the payload contents

decode

public static <T> AutoBean<T> decode(AutoBeanFactory factory,
                                     Class<T> clazz,
                                     String payload)

Decode an AutoBeanCodex payload.

Type Parameters:

T - the expected return type

Parameters:

factory - an AutoBeanFactory capable of producing AutoBean<T>

clazz - the expected return type

payload - a payload string previously generated by encode(AutoBean).getPayload().

Returns:

an AutoBean containing the payload contents

decodeInto

public static void decodeInto(Splittable data,
                              AutoBean<?> bean)

Copy data from a Splittable into an AutoBean. Unset values in the Splittable will not nullify data that already exists in the AutoBean.

Parameters:

data - the source data to copy

bean - the target AutoBean

encode

public static Splittable encode(AutoBean<?> bean)

Encodes an AutoBean. The actual payload contents can be retrieved through Splittable.getPayload().

Parameters:

bean - the bean to encode

Returns:

a Splittable that encodes the state of the AutoBean
