Method Detail

getType

public Class getType(String type)

map

public KsonTypeMapper map(String name,
                          Class c)

coerceReading

public Object coerceReading(Class type,
                            Object readObject)

map given Object to a target type. (needs support in coerceWriting also) Note one could add a pluggable Serializer/Coercer pattern here if required. Skipped for now for simplicity.

Parameters:

type - - of target field

readObject - - object read from string

Returns:

getDateTimeInstance

public DateFormat getDateTimeInstance()

setDateTimeInstance

public void setDateTimeInstance(DateFormat dateTimeInstance)

mapLiteral

public Object mapLiteral(String type)

getStringForType

public String getStringForType(Class<? extends Object> aClass)
