  • Constructor Details

    • ParameterBindingDocumentCodec

      public ParameterBindingDocumentCodec()
      Construct a new instance with a default CodecRegistry.

    • ParameterBindingDocumentCodec

      public ParameterBindingDocumentCodec(org.bson.codecs.configuration.CodecRegistry registry)
      Construct a new instance with the given registry.
      Parameters:
      registry - the registry

    • ParameterBindingDocumentCodec

      public ParameterBindingDocumentCodec(org.bson.codecs.configuration.CodecRegistry registry, org.bson.codecs.BsonTypeClassMap bsonTypeClassMap)
      Construct a new instance with the given registry and BSON type class map.
      Parameters:
      registry - the registry
      bsonTypeClassMap - the BSON type class map

    • ParameterBindingDocumentCodec

      public ParameterBindingDocumentCodec(org.bson.codecs.configuration.CodecRegistry registry, org.bson.codecs.BsonTypeClassMap bsonTypeClassMap, org.bson.Transformer valueTransformer)
      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 document

      Parameters:
      json -
      expressionParser -
      Returns:
      merged ExpressionDependencies object if expressions were found, otherwise ExpressionDependencies.none().
