Obtaining a List of Features with the License Manager
Declare Variables/Constants
String CONTACT_SERVER = "localhost";
String ScopeFeatureInfoPart1 = "<?xml version=\"1.0\" encoding=\"UTF-8\"?> "+
"<sentinelScope>"+
"<feature index=\"";
String ScopeFeatureInfoPart2 = "\"><name></name>"+
"<version></version>"+
"</feature>"+
"</sentinelScope>";
int iRetCode = (int)LicensingConstants.StatusCodes.SNTL_SUCCESS;
int iFeatureIndex = 0;

ApplicationContext appContext = null;
API Calls
To obtain features list, execute the APIs in the specified sequential order only:
>attrAppContext = new Attribute();
>attrAppContext.set(LicensingConstants.SNTL_ATTR_APPCONTEXT_CONTACT_SERVER, CONTACT_SERVER);
NOTE If instead the LSFORCEHOST or LSHOST environment variables are set, then the above mentioned steps are not required.
>appContext = new ApplicationContext(attrAppContext);
>Now call appContext.getInfo inside a while loop (incrementing the feature index, iFeatureIndex at each iteration, its initial value being 0), till the return code is SNTL_NO_MORE_FEATURES, as shown in the code snippet below:
try
{
attrAppContext = new Attribute();
attrAppContext.set(LicensingConstants.SNTL_ATTR_APPCONTEXT_CONTACT_SERVER, CONTACT_SERVER);
appContext = new ApplicationContext(attrAppContext);
while (iRetCode != (int)LicensingConstants.StatusCodes.SNTL_NO_MORE_FEATURES)
{
StringBuilder buff = new StringBuilder(ScopeFeatureInfoPart1);
buff.Append(iFeatureIndex++);
buff.Append(ScopeFeatureInfoPart2);
String ScopeFeatureInfo = buff.ToString();
String featureInfo = appContext.getInfo(ScopeFeatureInfo, LicensingConstants.SNTL_QUERY_FEATURE_INFO_LATEST);
/* Parse the XML output contained in featureInfo */
} /*end of while loop*/
}
catch (LicensingException e)
{
if (e.getStatusCode() != (int)LicensingConstants.StatusCodes.SNTL_NO_MORE_FEATURES)
{
Console.WriteLine("Got an exception : " + e);
System.Console.Out.WriteLine("Failed with status " + e.getStatusCode());
System.Console.Out.WriteLine("Status Message : \n" + e.Message);
}
else
{
Console.WriteLine("Reached end of enumeration...no more features");
}
}
On success during each iteration of the while loop, the featureInfo
string contains an XML-based output having the detailed information.
