Class SystemProperties

java.lang.Object
  gnu.classpath.SystemProperties

public class SystemProperties
extends java.lang.Object

The class manages the System properties. This class is only available to privileged code (i.e. code loaded by the bootstrap class loader) and therefore doesn't do any security checks. This class is separated out from java.lang.System to simplify bootstrap dependencies and to allow trusted code a simple and efficient mechanism to access the system properties.

Field Detail

properties

private static java.util.Properties properties

Stores the current system properties. This can be modified by setProperties(Properties) 55 , but will never be null, because setProperties(null) sucks in the default properties.

defaultProperties

private static final java.util.Properties defaultProperties

The default properties. Once the default is stabilized, it should not be modified; instead it is cloned when calling setProperties(null).
