Class SystemProperties

Helper for environment variables. This class helps to convert the environment variables to int or bool data types and also silently handles read permission errors.

For instructions how to set environment variables for your OS, see https://www.schrodinger.com/kb/1842.

Note that if you want to load any of these settings for your application from a configuration file, it is recommended your application load them at startup and call SetProperty(String, String) to set them.

Set the environment variable lucene.ignoreSecurityExceptions to false to change the read behavior of these methods to throw the underlying exception instead of returning the default value.
