LNK APIs
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.
- C API
  The C API enables applications to invoke maps and to develop adapters to use with HCL Link.
  - C API interface methods overview
    The map, card, and adapter object properties define the properties that can be set for each object. Use the C API interface methods to GET or SET the adapter object properties.
  - Object methods
  - Loading, running, and controlling maps
    There are various methods you can use to load, run, and control maps when you use APIs with HCL Link.
    - Loading and running maps
      Use the following methods to load specific maps, refresh maps when the maps have changed, and run maps.
    - Controlling and monitoring maps
      These methods allow map execution to be controlled from another thread and to report map progress.
    - Initialization and termination methods
      The following methods initialize the environment required for running maps and clean up the environment after the map run is complete.
    - Callbacks
      An API application uses callback to receive logging messages on a per-map basis or for global logging based on HCL Link initialization.
    - C API examples
      The examples included with the C API are located in the following directory: install_dir\examples\dk\dtxpi\c
  - Custom adapters
    The custom adapters interface makes it possible for users to develop adapters with as much functionality as those provided with the product.
- 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.
