                                             throws JsonMappingException

      Description copied from interface: `ContextualSerializer`
      Method called to see if a different (or differently configured) serializer is needed to serialize values of specified property. Note that instance that this method is called on is typically shared one and as a result method should NOT modify this instance but rather construct and return a new instance. This instance should only be returned as-is, in case it is already suitable for use.
      Specified by:
        `createContextual` in interface `ContextualSerializer`
      Parameters:
        `serializers` - Serializer provider to use for accessing config, other serializers
        `property` - Method or field that represents the property (and is used to access value to serialize). Should be available; but there may be cases where caller can not provide it and null is passed instead (in which case impls usually pass 'this' serializer as is)
      Returns:
        Serializer to use for serializing values of specified property; may be this instance or a new instance.
      Throws:
        `JsonMappingException`

    - #### serialize

          public void serialize(T value,
                       com.fasterxml.jackson.core.JsonGenerator gen,
                       SerializerProvider provider)
                         throws java.io.IOException

      Description copied from class: `JsonSerializer`
      Method that can be called to ask implementation to serialize values of type this serializer handles.
      Specified by:
        `serialize` in class `StdSerializer<T>`
      Parameters:
        `value` - Value to serialize; can not be null.
        `gen` - Generator used to output resulting Json content
        `provider` - Provider that can be used to get serializers for serializing Objects value contains, if any.
      Throws:
        `java.io.IOException`

    - #### serializeWithType

          public final void serializeWithType(T value,
                               com.fasterxml.jackson.core.JsonGenerator gen,
                               SerializerProvider provider,
                               TypeSerializer typeSer)
                                       throws java.io.IOException

      Description copied from class: `JsonSerializer`
      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 `JsonSerializer<T>`
      Parameters:
        `value` - Value to serialize; can not be null.
        `gen` - Generator used to output resulting Json content
        `provider` - Provider that can be used to get serializers for serializing Objects value contains, if any.
        `typeSer` - Type serializer to use for including type information
      Throws:
        `java.io.IOException`

    - #### serializeContents

          protected abstract void serializeContents(T value,
                               com.fasterxml.jackson.core.JsonGenerator jgen,
                               SerializerProvider provider)
                                             throws java.io.IOException

      Throws:
        `java.io.IOException`
