Platform来获取一些系统的路径和参数

在Eclipse的插件开发中，可以通过Platform来获取一些系统的路径和参数。 
假定Eclipse的安装路径为：D:/Java/eclipse 
创建的Workspace路径为：D:/Java/eclipse/workspace 

Platform.getNL()：zh_CN 
Platform.getWS()：win32 
Platform.getOS()：win32 
Platform.getOSArch()：x86 
Platform.getStateStamp()：155 
Platform.getUserLocation().getURL()：file:/D:/Profiles/windowsloginname/user/ 
Platform.getInstallLocation().getURL()：file:/d:/Java/eclipse/ 
Platform.getConfigurationLocation().getURL()：file:/d:/Java/eclipse/configuration/ 
Platform.getInstanceLocation().getURL()：file:/D:/Java/eclipse/workspace/ 
Platform.getLocation()：D:/Java/eclipse/workspace 
Platform.getLocation().toOSString()：D:/Java/eclipse/workspace 
Platform.getLogFileLocation()：D:/Java/eclipse/workspace/.metadata/.log 
Platform.getLogFileLocation().toOSString()：D:/Java/eclipse/workspace/.metadata/.log 
Platform.getPluginStateLocation(Platform.getPlugin("NamedPlugin"))：D:/Java/eclipse/workspace/.metadata/.plugins/NamedPlugin 
Platform.getPlugin("NamedPlugin").getStateLocation()：D:/Java/eclipse/workspace/.metadata/.plugins/NamedPlugin 
Platform.getPlugin("NamedPlugin").getDescriptor()：NamedPlugin_1.0.0 
Platform.getPlugin("NamedPlugin").getDescriptor().getLabel()：Plug-in Name 
Platform.getPlugin("NamedPlugin").getDescriptor().getProviderName()：ProviderName 
Platform.getPlugin("NamedPlugin").getDescriptor().getUniqueIdentifier()：NamedPlugin 
Platform.getPlugin("NamedPlugin").getDescriptor().getInstallURL()：platform:/plugin/NamedPlugin_1.0.0/ 
Platform.getPlugin("NamedPlugin").getDescriptor().getInstallURL().getPath()：/plugin/NamedPlugin_1.0.0/
