    • getUuidRepresentation

      public UuidRepresentation getUuidRepresentation()
      Gets the UUID representation to use when encoding instances of UUID and when decoding BSON binary values with subtype of 3.

      The default is UuidRepresentation.UNSPECIFIED, If your application stores UUID values in MongoDB, you must set this value to the desired representation. New applications should prefer UuidRepresentation.STANDARD, while existing Java applications should prefer UuidRepresentation.JAVA_LEGACY. Applications wishing to interoperate with existing Python or .NET applications should prefer UuidRepresentation.PYTHON_LEGACY or UuidRepresentation.C_SHARP_LEGACY, respectively. Applications that do not store UUID values in MongoDB don't need to set this value.

      Returns:
      the UUID representation, which may not be null
      Since:
      3.12

    • getServerApi

      @Nullable public ServerApi getServerApi()

      Returns:
      the server API, which may be null
      Since:
      4.3

    • getAutoEncryptionSettings

      @Nullable public AutoEncryptionSettings getAutoEncryptionSettings()
      Gets the auto-encryption settings.

      Client side encryption enables an application to specify what fields in a collection must be encrypted, and the driver automatically encrypts commands and decrypts results.

      Automatic encryption is an enterprise only feature that only applies to operations on a collection. Automatic encryption is not supported for operations on a database or view and will result in error. To bypass automatic encryption, set bypassAutoEncryption=true in ClientSideEncryptionOptions.

      Explicit encryption/decryption and automatic decryption is a community feature, enabled with the new com.mongodb.client.vault .ClientEncryption type. A MongoClient configured with bypassAutoEncryption=true will still automatically decrypt.

      Automatic encryption requires the authenticated user to have the listCollections privilege action.

      Supplying an encryptedFieldsMap provides more security than relying on an encryptedFields obtained from the server. It protects against a malicious server advertising false encryptedFields.

      Returns:
      the auto-encryption settings, which may be null
      Since:
      3.11

    • getClusterSettings

      Returns:
      the SSL settings

    • getSocketSettings

      public SocketSettings getSocketSettings()

      Returns:

      See Also:

    • getHeartbeatSocketSettings
