public class LicenseManager
extends java.lang.Object
```
LicenseManager is a helper class to manage licenses of ChemAxon products. The licenses are stored in xml files (license.cxl) and are digitally signatured by ChemAxon. The default location of the license file is USER_HOME/chemaxon/license.cxl, but this can arbitrarily be changed. The old license files (licenses.dat) are supported till September 2008.

Since:

Marvin 5.0.1
