Descriptions of Link runtime services.
SDK
The LNK programming interface includes language-specific methods and objects that provide common functionality across multiple environments.
Link programming interface overview
The Link programming interface is an object-oriented approach that enables applications to invoke HCL Link maps, thus removing reliance on command lines.
Link programming interface function overview
Use the Link programming interface to load, run and control maps.
Monitor and manage map overview
These methods enable the execution of a map to be controlled from another thread, and for the progress of a map to be reported.
RegisterStatusMethod
This method allows for a user-provided status method to be registered for a particular map object.

Runtimes
Descriptions of Link runtime services.
- REST API
  The REST Runtme provides a REST API used to run maps and flows that have been deployed.
- Flow Command Server
  Deploy a flow from the HCL Link to the local filesystem using Execution flow server definition.
- Map Command Server
  To use the Map Command Server to execute a map, you will prepare the maps for execution.
- SDK
  The LNK programming interface includes language-specific methods and objects that provide common functionality across multiple environments.
  - Link programming interface overview
    The Link programming interface is an object-oriented approach that enables applications to invoke HCL Link maps, thus removing reliance on command lines.
    - Link programming interface methods
      The Link programming interface map, card, and adapter object properties define the properties that can be set for each object. Use these methods to GET or SET the object properties.
    - Link programming interface object overview
      The Link programming interface is based on map, card, adapter, connection, and stream objects.
    - Link programming interface function overview
      Use the Link programming interface to load, run and control maps.
      - Scenario: running Link programming interface maps
        Code examples of running maps are installed with the Development Kit in the install_dir\examples\dk\dtxpi directory, where install_dir represents the directory in which the DK is installed.
      - Monitor and manage map overview
        These methods enable the execution of a map to be controlled from another thread, and for the progress of a map to be reported.
        Abort
        This method aborts the map defined by the map object. The map must be in the running or paused state when this method is called.
        Continue
        This method continues the map defined by the map object.
        Pause
        This method pauses the map defined by the map object.
        RegisterStatusMethod
        This method allows for a user-provided status method to be registered for a particular map object.
      - Load and run map overview
        Use the loading and running methods to load specific maps, refresh maps when the maps have changed, and run maps.
  - C API
    The C API enables applications to invoke maps and to develop adapters to use with HCL Link.
  - Python API
    Use the Python API to create, edit, and run maps and schemas from a Python program. For details, see the documentation installed in install_dir/python/api/hip/docs/html/index.html. Examples of the Python API are installed in install_dir/python/api/examples. Documentation for the Python API examples is available in install_dir/python/api/docs/html/examples.html.
  - Java API
    The Java API interfaces enable you to create, edit, and run maps and schemas from a Java™ program.
  - Java Tools
    The Java™ Tools provide objects and JNI utilities that you can use to get information about your map instances.

RegisterStatusMethod

This method allows for a user-provided status method to be registered for a particular map object.

This status method will be invoked at critical points during the execution of the map.

If the status method returns MPI_STATE_ABORTED, execution of the map will stop immediately. After aborting a map, it is possible to start it again from the beginning using the Run method.

iNotifyWhen is a bitmask that governs when the status method will be called. It can be any combination of the values listed.

MPI_EVENT_MAP_EVENTS	Notify whenever a map starts or completes.
MPI_EVENT_ALL_EVENTS	Notify all card, map, and burst events.
