viaJSON

public static <T> T viaJSON(T valueType)
                     throws IOException

Useful for testing. Performs a round trip via a JSON string allowing ser/deser to be tested andv erified.

Note that this deliberately uses a very strict ObjectMapper since we need to be sure that the source object is fully recreated without errors.

Type Parameters:

T - The object type

Parameters:

valueType - The object to be converted

Returns:

A copy of the object performed via JSON.

Throws:

IOException - If there are deserialization issues.
