IExternalLicenseManager Interface

Visual Signal ExternalBase Class Library Documentation

API version 1.5.2

[This is preliminary documentation and is subject to change.]

IExternalLicenseManager - Interface of external license manager. If license control is required in an external module, a license manager must be implemented according to this interface, and its ID registered in the module. Visual Signal will be responsible for the creation and initialization of all license managers available in the External directory. For security reasons, the implemented license manager *must* be included in the same assembly as the associated external modules to prevent spoofing. However, it is possible to implement IExternalLicenseManager as proxy license managers to be included in various assemblies, and have the proxy license managers accessing a central license control manager located in a separate assembly. *** Note that the implemented license manager class, as well as license controlled modules must be "sealed" to prevent re-inheriting the classes.
