SystemPropertiesConfigurationModel (Jersey 2.45 API)

java.lang.Object
- org.glassfish.jersey.internal.config.SystemPropertiesConfigurationModel

All Implemented Interfaces:

Configuration, ExtendedConfig, ExternalConfigurationModel<Void>
```
public class SystemPropertiesConfigurationModel
extends Object
implements ExternalConfigurationModel<Void>
```
The External Configuration Model that supports System properties. The properties are listed in a property class in a form of public static final String property name. The String value of the property name is searched among the System properties. The property scan is performed only when CommonProperties.ALLOW_SYSTEM_PROPERTIES_PROVIDER is set to true.
