All Implemented Interfaces:

JsonFormatVisitable

public class StringCollectionSerializer
extends StaticListSerializerBase<Collection<String>>

Efficient implement for serializing Collections that contain Strings. The only complexity is due to possibility that serializer for String may be override; because of this, logic is needed to ensure that the default serializer is in use to use fastest mode, or if not, to defer to custom String serializer.

serialize

public void serialize(Collection<String> value,
 JsonGenerator g,
 SerializationContext provider)
               throws JacksonException

Description copied from class: ValueSerializer

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

Specified by:

serialize in class StdSerializer<Collection<String>>

Parameters:

value - Value to serialize; can not be null.

g - Generator used to output resulting Json content

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

Throws:

JacksonException

serializeWithType

public void serializeWithType(Collection<String> value,
 JsonGenerator g,
 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.

Specified by:

serializeWithType in class StaticListSerializerBase<Collection<String>>

Parameters:

value - Value to serialize; can not be null.

g - 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
