java.lang.Objectjogamp.common.os.PlatformPropsImpl
com.jogamp.common.os.Platform
public class Platform
Utility class for querying platform specific properties.
Some field declarations and it's static initialization has been delegated
to it's super class PlatformPropsImpl
to solve
static initialization interdependencies w/ the GlueGen native library loading
and it's derived information getMachineDescription()
, is32Bit()
, ..
This mechanism is preferred in this case to avoid synchronization and locking
and allow better performance accessing the mentioned fields/methods.
