Examples with DatasetTypeClient io.cdap.cdap.client.DatasetTypeClient used on opensource projects

Example 1 with DatasetTypeClient

use of io.cdap.cdap.client.DatasetTypeClient in project cdap by caskdata.

the class GenerateClientUsageExample method datasetTypeClient.

public void datasetTypeClient() throws Exception {
    // Construct the client used to interact with CDAP
    DatasetTypeClient datasetTypeClient = new DatasetTypeClient(clientConfig);
    // Fetch the dataset type information using the type name
    DatasetTypeMeta datasetTypeMeta = datasetTypeClient.get(NamespaceId.DEFAULT.datasetType("someDatasetType"));
    // Fetch the dataset type information using the classname
    datasetTypeClient.get(NamespaceId.DEFAULT.datasetType(SomeDataset.class.getName()));
}
