    - Chapter 12 Metaconnectors for LEI
      This chapter provides an introduction to LEI Metaconnectors and contains information for creating and using the different types of Metaconnectors.
      - Introduction to Metaconnectors
        A metaconnector provides preprocessing operations on connection data prior to transfer within a defined activity form.
      - Collapse/Expand Metaconnector
        Use a Collapse/Expand Metaconnector to group or ungroup multiple records, with a common key value, into a single record with multivalue fields. The Collapse/Expand Metaconnector wraps another Connector or Metaconnector and collapses records on Fetch operations. It then expands them on write operations according to user-defined criteria. The Collapse/Expand Metaconnector has no effect on metadata operations; it simply passes through Create, Drop, and Action statements.
      - Collapse/Expand Metaconnection Document
        To create a new Collapse/Expand metaconnection document in IBM® Lotus Enterprise Integrator® (LEI), do the following.
      - Collapse/Expand Metaconnector Properties
        The Collapse/Expand Metaconnector Properties are described as follows.
      - Using the Collapse/Expand Metaconnector with a Replication Activity
        When using a Collapse/Expand Metaconnection with a Replication activity, the key fields and the grouping keys need to be the same and in the same order in the Metaconnection definition as in the Replication activity definition to work properly.
      - Collapse/Expand Metaconnector Data Types
        Since the Collapse/Expand Metaconnector has no external database, it always operates with IBM® Lotus Enterprise Integrator® (LEI) or Domino® Enterprise Connection Services (DECS) data types. For key fields, all LEI or DECS datatypes convert within their class (number, datetime, or stream); in addition, precision and overflow checking are performed as needed. For non-key fields, on Fetch, external single-value data types map to internal multivalue data types, and vice-versa on output. Therefore, an external number class type maps to a number list; a datetime to a datetime list; and text to a text list. Note that binary data types (unformatted BLOB or formatted binary types such as composite) cannot be mapped to multivalue types.
      - Meter Metaconnector
        Use the Meter metaconnector to track data flowing to and from another connection or metaconnection. The Meter metaconnector has no effect on any operations; it simply monitors the data transferred. Results from the metering are logged to a file. The specific information logged is configurable through use of the Meter metaconnection document.
      - Meter Metaconnection Document
        To create a new Meter metaconnection document in IBM® Lotus Enterprise Integrator® (LEI), do the following.
      - Meter Metaconnector Properties
        The Meter Metaconnector Properties are described.
      - Supported characteristics of the Meter metaconnector
        The following list captures supported characteristics of the Meter metaconnector.
      - Order Metaconnector
        Use an Order metaconnector to obtain consistent ordering of result sets from other Connections. The Order metaconnector wraps another connector and orders the result set based on user-defined criteria. Order options are available. The Order Metaconnector has no effect on data operations, other than producing a result set or fetching - it simply passes through Insert, Update, Remove, Create, Drop, and Action statements.
      - Order Metaconnection Document
        To create a new Order metaconnection document in IBM® Lotus Enterprise Integrator® (LEI), do the following.
      - Order Metaconnector Properties
        The Order metaconnector properties are described as follows.
      - Using the Order Metaconnector with a Replication Activity
        Replication depends on an ascending sort to operate properly. Do not use the Sort Descending option of this metaconnector when performing Replication activities.
      - Order Metaconnector Data Types
        Since the Order Metaconnector has no external database, it always operates with IBM® Lotus Enterprise Integrator® (LEI) data types. All LEI data types convert within their class (number, datetime, or stream). Precision and overflow checking are performed as needed.
      - Trace Metaconnector
        The Trace Metaconnector allows you to trace events associated with a specified sub connection. You may specify options including where to capture data (either to the IBM® Lotus Enterprise Integrator® (LEI) console or to a user-specified file name) and whether or not to include a timestamp with each trace log entry.
      - Trace Metaconnection Document
        To create a new Trace metaconnection document in IBM® Lotus Enterprise Integrator® (LEI), do the following.
      - Trace Metaconnector Properties
        The Trace Metaconnector options and their corresponding LotusScript® Extensions (LC LSX) properties are described as follows.
      - Example Trace Metaconnetor LC LSX Code
        Example Trace Metaconnector LotusScript® Extensions (LC LSX) code is shown as follows.
  - LSX for Lotus® Connectors
    LotusScrip Extensions for Lotus® Connectors (LC LSX) enhances the power of Notes® by extending its scripting to data outside of Notes through the use of Lotus Connectors. The programming model is independent of the individual connector. This eliminates the need to learn each individual system, while at the same time allowing experienced users to access the individual features of a specific system.
  - Accessing external databases through LS:DO
    LS:DO has been in maintenance mode since R5. Developers are advised not to use it. Developers should use the Lotus® Connector LSX for (LCLSX) when accessing external data sources.
- Javadoc™ for Domino® Designer related APIs
  As part of providing additional Java™ reference documentation, Domino® Designer ships with a help plugin that contains Javadoc™ for additional Domino Designer related APIs.
- Accessibility and keyboard shortcuts
  Accessibility features assist users who have a disability, such as restricted mobility or limited vision, to use information technology content successfully.

Meter Metaconnector

Use the Meter metaconnector to track data flowing to and from another connection or metaconnection. The Meter metaconnector has no effect on any operations; it simply monitors the data transferred. Results from the metering are logged to a file. The specific information logged is configurable through use of the Meter metaconnection document.

Connectivity to a Meter Metaconnection

There are no connectivity requirements beyond those required for the underlying connection to which the Meter metaconnection is connecting. Since there is no external database for the Meter metaconnection itself, there is no connectivity test.
