Method Detail

create

public static <T> Verjson<T> create(Class<T> valueClass,
                                    Versions versions)

configure

protected void configure(Versions versions)

determineHighestSourceVersion

protected long determineHighestSourceVersion()

createStepSequencer

protected StepSequencer createStepSequencer()

getNamespace

protected String getNamespace()

getMapper

protected com.fasterxml.jackson.databind.ObjectMapper getMapper()

write

public String write(T obj)
             throws com.fasterxml.jackson.core.JsonProcessingException

Serializes the given object to a String

Throws:

com.fasterxml.jackson.core.JsonProcessingException

writePlain

public String writePlain(T obj)
                  throws com.fasterxml.jackson.core.JsonProcessingException

Serializes the given object without any metadata to a String. This is basically the raw serialized object from the data element. Since the metadata is missing, this Json can not be read using the read(..) methods, except the readPlain-method - if the version is manually passed.

Throws:

com.fasterxml.jackson.core.JsonProcessingException

readTree

public com.fasterxml.jackson.databind.JsonNode readTree(String json)
                                                 throws IOException

Throws:

IOException

wrapPlainNode

protected com.fasterxml.jackson.databind.JsonNode wrapPlainNode(com.fasterxml.jackson.databind.JsonNode node,

readPlain

public T readPlain(com.fasterxml.jackson.databind.JsonNode node,
                   long version)
            throws VersionNotSupportedException,
                   NamespaceMismatchException,
                   ProcessStepException,
