toUpdateValue

public String toUpdateValue(GuiMappingContext context,
 Object newValue)

the updated value

toJson

public Object toJson(GuiMappingContext context,

Parameters:

context - a context of the repr.

target - a target object

json - json object, ignored

Returns:

the target object

isHistoryValueSupported

public boolean isHistoryValueSupported()
