How do you add a flag so FlxCapabilityResponseGetVendorDictionary detects returns at runtime?

Question

Using the FlexNet Embedded 2014.09 client to obtain a license from an instance of FlexNet Operations, when creating the license model, how do you add a Boolean field to indicate whether the license can be returned or not, as well as a string field for any additional info? The need here is to query these fields so as to prevent/allow the returning of licenses at run-time. How can this information be queried from the client?

Answer

This can be done by implementing the com.flexnet.opsembedded.publicapi.DeviceRequestHandler class. You can use this to add something to the response.

Attached is some sample code based on the samples that ship with FNO (CustomDeviceRequestHandler.java). All of the test stuff has been stripped out and just the handler return test is included as the key value pair. It is also possible to use the license model vendor string to add a value, either at entitlement time or license model specific if needed (just need to set when to create the string in the license model).

With this situation, first need to add a custom attribute to the FNO instance (per the DeviceRequestHandler class, which should be modified for the specific needs before doing a "flexnet site make" and then restarting the FNO server to implement the modifications).

Then, via the FNO admin console, add it to the license model (see attached license_model.jpg)

Next, created an entitlement that sets the value (see attached entitlement.jpg)

Then, back at your client, modify the capabilityrequest example to display the vendor string:

if ( !FlxPublisherAcquireLicenses(

clientObjects->publisher,

&license,

clientObjects->licenseSources,

survey,

version,

1,

0,

0,

error) )

{

DisplayErrorString(_T("acquiring survey license"), error);

return FLX_FALSE;

}

printf("Vendor string: %s\n", FlxLicenseGetVendorString(license));

This then takes the license that had been populated by the acquire call and used it to read the vendor string:

INFO: number of features loaded from capability response: 4
Vendor string: true
INFO: acquired license
INFO: deleted client objects
