OEShapeIsLicensedΒΆ

bool OEShapeIsLicensed(const char *feature=0, unsigned int *expdate=0)

Determine whether a valid license file is present. This function may be called without a legitimate run-time license to determine whether it is safe to call any of OEShape’s functionality.

The features argument can be used to check for a valid license to OEShape along with that feature. For example, to verify that OEShape can be used from Python:

if (!oeshape.OEShapeIsLicensed("python"))
    OEThrow.Warning("OEShape is not licensed for the python feature");

The second argument can be used to get the expiration date of the license. This is an array of size three with the date returned as [day, month, year]. Even if the function returns false due to an expired license, the expdate will show that expiration date. A value of a zeroes implies that no license or date was found.

OEUIntArray expdate = new OEUIntArray(3);
if (oeshape.OEShapeIsLicensed(0, expdate))
{
    OEThrow.Info("License expires: day: %d  month: %d year: %d",
                 expdate[0], expdate[1], expdate[2]);
}
