Method Details

serialize

public void serialize(Object value,
 JsonGenerator gen,
 SerializationContext ctxt)
               throws JacksonException

Description copied from class: ValueSerializer

Method that can be called to ask implementation to serialize values of type this serializer handles.

Overrides:

serialize in class ToEmptyObjectSerializer

Parameters:

value - Value to serialize; can not be null.

gen - Generator used to output resulting Json content

ctxt - Context that can be used to get serializers for serializing Objects value contains, if any.

Throws:

JacksonException

serializeWithType

public final void serializeWithType(Object value,
 JsonGenerator gen,
 SerializationContext ctxt,
 TypeSerializer typeSer)
                             throws JacksonException

Description copied from class: ValueSerializer

Method that can be called to ask implementation to serialize values of type this serializer handles, using specified type serializer for embedding necessary type information.

Default implementation will throw UnsupportedOperationException to indicate that proper type handling needs to be implemented.

For simple datatypes written as a single scalar value (JSON String, Number, Boolean), implementation would look like:

  // note: method to call depends on whether this type is serialized as JSON scalar, object or Array!
  typeSer.writeTypePrefixForScalar(value, gen);
  serialize(value, gen, provider);
  typeSer.writeTypeSuffixForScalar(value, gen);

and implementations for type serialized as JSON Arrays or Objects would differ slightly, as START-ARRAY/END-ARRAY and START-OBJECT/END-OBJECT pairs need to be properly handled with respect to serializing of contents.

Overrides:

serializeWithType in class ToEmptyObjectSerializer

Parameters:

value - Value to serialize; can not be null.

gen - Generator used to output resulting Json content

ctxt - Context that can be used to get serializers for serializing Objects value contains, if any.

typeSer - Type serializer to use for including type information

Throws:

JacksonException

isEmpty

public boolean isEmpty(SerializationContext provider,
 Object value)

Description copied from class: ValueSerializer

Method called to check whether given serializable value is considered "empty" value (for purposes of suppressing serialization of empty values).

Default implementation will consider only null values to be empty.

Overrides:

isEmpty in class ToEmptyObjectSerializer

failForEmpty

protected void failForEmpty(SerializationContext prov,
 Object value)
