Descriptions of Link runtime services.
SDK
The LNK programming interface includes language-specific methods and objects that provide common functionality across multiple environments.
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.
mpiPropertyGetText
The C API uses different interface methods, including mpiPropertyGetText.

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.
  - C API
    The C API enables applications to invoke maps and to develop adapters to use with HCL Link.

        The C API uses different interface methods, including mpiPropertyGetAllPropertiesXML.
      - mpiPropertyGetPropertiesXML
        The C API uses different interface methods, including mpiPropertyGetPropertiesXML.
      - mpiPropertySetPropertiesXML
        The C API uses different interface methods, including mpiPropertySetPropertiesXML.
    - 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.
    - 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.

mpiPropertyGetText

The C API uses different interface methods, including mpiPropertyGetText.

MPIRC mpiPropertyGetText (HMPIOBJ  hObject,MPIPROP  iProperty,int  iIndex,const char
 **ppText,size_t  *pnLen)

Inputs

hObject: Handle of the HCL Link object.
iProperty: Property ID
iIndex: Index of the property.

Outputs

ppText: Pointer to the pointer value.
pnLen: Length of the text item.

Returns

Success status.

Note: If pnLen is returned as 0, the string is null- terminated.
