public Object getEmptyValue(DeserializationContext ctxt)

```
    Description copied from class: JsonDeserializer
    
    Method called to determine value to be used for "empty" values (most commonly when deserializing from empty JSON Strings). Usually this is same as JsonDeserializer.getNullValue(com.fasterxml.jackson.databind.DeserializationContext) (which in turn is usually simply Java null), but it can be overridden for specific types. Or, if type should never be converted from empty String, method can also throw an exception.
    This method may be called once, or multiple times, depending on what JsonDeserializer.getEmptyAccessPattern() returns.
    Default implementation simply calls JsonDeserializer.getNullValue(com.fasterxml.jackson.databind.DeserializationContext) and returns value.
    
    Overrides:
    
    getEmptyValue in class JsonDeserializer<Object>
    
    Throws:
    
    JsonMappingException
  - _deserializeFromEmptyStringDefault

protected Object _deserializeFromEmptyStringDefault(DeserializationContext ctxt)

    Overrides:

    Throws:
    
    IOException
  - _firstHyphenOrUnderscore
