      • MapCodec

        public MapCodec()
        Deprecated.
        Construct a new instance with a default CodecRegistry

      • MapCodec

        public MapCodec​(CodecRegistry registry)
        Deprecated.
        Construct a new instance with the given registry
        Parameters:
        registry - the registry

      • MapCodec

        public MapCodec​(CodecRegistry registry,
                BsonTypeClassMap bsonTypeClassMap)
        Deprecated.
        Construct a new instance with the given registry and BSON type class map.
        Parameters:
        registry - the registry
        bsonTypeClassMap - the BSON type class map

      • MapCodec

        public MapCodec​(CodecRegistry registry,
                BsonTypeClassMap bsonTypeClassMap,
                Transformer valueTransformer)
        Deprecated.
        Construct a new instance with the given registry and BSON type class map. The transformer is applied as a last step when decoding values, which allows users of this codec to control the decoding process. For example, a user of this class could substitute a value decoded as a Document with an instance of a special purpose class (e.g., one representing a DBRef in MongoDB).
        Parameters:
        registry - the registry
        bsonTypeClassMap - the BSON type class map
        valueTransformer - the value transformer to use as a final step when decoding the value of any field in the map

      • getEncoderClass

        public java.lang.Class<java.util.Map<java.lang.String,​java.lang.Object>> getEncoderClass()
        Deprecated.
        Description copied from interface: Encoder
        Returns the Class instance that this encodes. This is necessary because Java does not reify generic types.
        Specified by:
        getEncoderClass in interface Encoder<java.util.Map<java.lang.String,​java.lang.Object>>
        Returns:
