    - #### readResponse

          Response readResponse(WarningMessageCallback callback)
                         throws java.sql.SQLException,
                                java.io.IOException

      Reads the response from the server.
      Parameters:
        `callback` - Callback object for warnings, `null` for default callback
      Returns:
        `Response` read.
      Throws:
        `java.sql.SQLException` - For errors returned from the server, or when attempting to read
        `java.io.IOException` - For errors reading the response from the connection.

    - #### releaseObject

          void releaseObject(int operation,
                             int objectId)
                      throws java.sql.SQLException

      Release object.
      Parameters:
        `operation` - Operation
        `objectId` - ID of the object to release
      Throws:
        `java.sql.SQLException`

    - #### readSqlResponse

          SqlResponse readSqlResponse(WarningMessageCallback callback)
                               throws java.sql.SQLException,
                                      java.io.IOException

      Convenience method to read a Response to a SqlResponse
      Parameters:
        `callback` - Callback object for warnings, `null` for default callback
      Returns:
        SqlResponse
      Throws:
        `java.sql.SQLException` - For errors returned from the server, or when attempting to read.
        `java.io.IOException` - For errors reading the response from the connection.

    - #### getBlrCalculator

          BlrCalculator getBlrCalculator()

      Returns:
        The `BlrCalculator` instance for this database.

    - #### enqueueDeferredAction

          void enqueueDeferredAction(DeferredAction deferredAction)

      Enqueue a deferred action.

      FbDatabase implementations that do not support deferred actions are allowed to throw an `UnsupportedOperationException`

      Parameters:
        `deferredAction` - Deferred action

    - #### consumePackets

          void consumePackets(int numberOfResponses,
                              WarningMessageCallback warningCallback)

      Consumes packets notifying for warnings, but ignoring exceptions thrown from the packet.

      This method should only be used inside the implementation if either packets need to be ignored, or to ensure that there is no backlog of packets (eg when an exception occurs during processing of multiple package responses).

      Parameters:
        `numberOfResponses` - Number of responses to consume.
        `warningCallback` - Callback for warnings

    - #### getInfo

          byte[] getInfo(int operation,
                         int handle,
                         byte[] requestItems,
                         int maxBufferLength,
                         WarningMessageCallback warningMessageCallback)
                  throws java.sql.SQLException

      Generic info request.

      The implementation does not perform handle validation nor notification of error dispatchers. Doing that is the responsibility of the caller.

      Parameters:
        `operation` - Operation code
        `handle` - Handle (db, transaction, statement, blob, etc)
        `requestItems` - Information items to request
        `maxBufferLength` - Maximum response buffer length to use
        `warningMessageCallback` - Callback for warnings when reading the response (can be `null` to use database default)
      Returns:
        The response buffer (note: length is the actual length of the response, not `maxBufferLength`)
      Throws:
        `java.sql.SQLException` - For errors retrieving the information
