Method Detail

getInstance

public static SystemUtil getInstance()

This method gets the singleton instance of this SystemUtil.
This design is the best compromise between easy access (via this indirection you have direct, static access to all offered functionality) and IoC-style design which allows extension and customization.
For IoC usage, simply ignore all static getInstance() methods and construct new instances via the container-framework of your choice (like plexus, pico, springframework, etc.). To wire up the dependent components everything is properly annotated using common-annotations (JSR-250). If your container does NOT support this, you should consider using a better one.

Returns:

the singleton instance.

getSystemInformation

public SystemInformation getSystemInformation()

This method gets the SystemInformation for the operating system running this java virtual-machine. It lets you determine specific things (e.g. if you are running on "MS Windows" or on a "mobile device").

Specified by:

getSystemInformation in interface SystemUtil

Returns:

the SystemInformation.
