To compile the framework, example plugins and example apps, we recommend using CMake. Download CMake from https://cmake.org/download/.
To build and run the examples, please follow the steps below:
Unzip the distribution file info a folder (e.g. DataProvider)
Create a build folder (e.g. Build on the same level as DataProvider)
> cd Build
> cmake ../DataProvider
On Linux/mac, build the solution with:
On Windows, open the project file and build with the selected compiler (e.g. Visual Studio).
The build step will build:
To run the test driver:
cd ExampleApps/TestDriver/ ./TestDriver ../../ExamplePlugins/MinimalPlugin/cdp_MinimalPlugin MINIMAL
Creating a DataProviderPlugin
There are three steps to creating a DataProviderPlugin
Step 1: Create the plugin
The main file defines the plugin. You define a version and a method for creating the Factory. One file can contain many data providers. The initializeDataProviderPlugin method is called by the host to initialize the provider(s).
Step 2: Create the data provider factory
The factory is responsible for instantiation and deletion of the DataProvider, providing information about the provider and checking if the provided ModelKey is supported by the provider. To create the factory, derive from CDPDataProviderFactory and implement the 4 pure virtual methods.
Step 3: Create the data provider
The provider is where all the CAE data is communicated to the host. To create a provider, derive from CDPDataProvider and implement the 7 pure virtual methods.
Using Data Providers in Envision for Web
Data providers can be used with the RemoteModel server (CeeCloudServer). To load your data provider, set the C3_UG_DATA_PROVIDER_FOLDER environment variable to point to the folder with your data provider. The CeeCloudServer will load all data providers in the specified folder. The data provider needs to comply to the following naming scheme:
cdp_MyDataProvider.dll (Windows), cdp_MyDataProvider.so (Linux)
The server will list the registered data providers when a file is opened.
Using Data Providers in Envision Analyzer
To use your data provider with CEETRON Analyzer Desktop, define the environment variable CEE_DATA_PROVIDERS_FOLDER to point to the folder where your data provider is located. CEETRON Analyzer will load all data providers in the specified folder. The data provider file needs to follow the same naming scheme as described above.
Polling of the data provider can be controlled by two settings in the Advanced pane of the Settings dialog:
Enable Data Provider polling
Show last state when a state is added
