public JsonSerializer<?>	createContextual(SerializerProvider Serializer provider to use for accessing config, other serializers provider, BeanProperty 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 cannot provide it and null is passed instead (in which case impls usually pass 'this' serializer as is) property) Implements com.fasterxml.jackson.databind.ser.ContextualSerializer.createContextual.

public void	serializeFieldsUsing(Map<?, ?> value, JsonGenerator gen, SerializerProvider provider, JsonSerializer<Object> ser) Method called to serialize fields, when the value type is statically known, so that value serializer is passed and does not need to be fetched from provider.

public MapSerializer	withFilterId(Object filterId) Overrides com.fasterxml.jackson.databind.JsonSerializer.withFilterId. References Deprecated `MapSerializer` is deprecated or references (maybe indirectly) at least one deprecated element. Mutant factory method that is called if contextual configuration indicates that a specific filter (as specified by `filterId`) is to be used for serialization.
