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 object overview
The Link programming interface is based on map, card, adapter, connection, and stream objects.
Link programming interface map object
The Link programming interface creates a map object instance from the byte array representing a compiled map file. The hierarchies of map, card and adapter objects are created by this method.
Map object properties
Properties can be set and their values can be obtained by executing the methods defined by the map object.
General map properties
The general properties for map objects provide high-level information about the map object.

Runtimes
Descriptions of Link runtime services.
- REST API
  The REST Runtime 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 object hierarchy
        The Link programming interface objects have a relationship to each other defined by a specific hierarchy.
      - Link programming interface properties
        The Link programming interface methods provide a means to query or modify properties of objects.
      - Link programming interface map object
        The Link programming interface creates a map object instance from the byte array representing a compiled map file. The hierarchies of map, card and adapter objects are created by this method.
        Map object properties
        Properties can be set and their values can be obtained by executing the methods defined by the map object.
        General map properties
        The general properties for map objects provide high-level information about the map object.
        MPIP_MAP_DESTROY_OBJECT_POOL
        If the value is set to TRUE, the objects related to the map instance will be destroyed after the map is executed.
        MPIP_MAP_INSTANCE
        This is a unique instance number for the map object.
        MPIP_MAP_MAP_NAME
        This is the fully qualified name of the map for the map object.
        MPIP_OBJECT_ERROR_CODE
        The error code from the last operation on the map object.
        MPIP_OBJECT_ERROR_MSG
        The error message from the last operation on the map object.
        Map trace properties
        The trace properties for map objects allow you to set the trace settings for map execution.
        Map workspace properties
        The workspace properties for map objects allow you to define the workspace settings for map execution.
        Map sliding century properties
        Use the sliding century properties for map objects to define the sliding century settings for map execution.
        Map custom validation properties
        Use the custom validation properties for map objects to define custom validation settings for map execution.
        Map audit properties
        The audit properties for map objects allow you to set the audit settings for map execution.
        Map retry properties
        The map retry properties for map objects allow you to define the map retry settings for map execution.
        Map object methods
        The map object methods are defined by the map object.
      - Card object overview
        The card object is an abstraction of a card in a map.
      - Adapter object overview
        An adapter object is created for each card when a map instance object is created.
    - Link programming interface function overview
      Use the Link programming interface to load, run and control 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.

General map properties

The general properties for map objects provide high-level information about the map object.
