Simple "bogus" serializer that will just serialize an empty Object for any given value. Quite similar to UnknownSerializer with the exception that serialization never fails.

Method Summary

Modifier and TypeMethod and Description
public void
acceptJsonFormatVisitor(JsonFormatVisitorWrapper visitor, JavaType typeHint)

Overrides tools.jackson.databind.ser.std.StdSerializer.acceptJsonFormatVisitor.

Implements tools.jackson.databind.jsonFormatVisitors.JsonFormatVisitable.acceptJsonFormatVisitor.

Default implementation specifies no format.

public boolean
isEmpty(SerializationContext provider, Object value)

Overrides tools.jackson.databind.ValueSerializer.isEmpty.

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

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

Implements abstract tools.jackson.databind.ser.std.StdSerializer.serialize.

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

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

Overrides tools.jackson.databind.ValueSerializer.serializeWithType.

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.

public void acceptJsonFormatVisitor(JsonFormatVisitorWrapper visitor, JavaType typeHint) throws JacksonException

Overrides tools.jackson.databind.ser.std.StdSerializer.acceptJsonFormatVisitor.

Implements tools.jackson.databind.jsonFormatVisitors.JsonFormatVisitable.acceptJsonFormatVisitor.

Doc from tools.jackson.databind.ser.std.StdSerializer.acceptJsonFormatVisitor.

Default implementation specifies no format. This behavior is usually overriden by custom serializers.

Doc from tools.jackson.databind.ValueSerializer.isEmpty.

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.

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

Overrides tools.jackson.databind.ValueSerializer.serializeWithType.

Doc from tools.jackson.databind.ValueSerializer.serializeWithType.

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.
