Detailed Description

Class which provides the run-time platform information Ogre runs on.

Ogre is designed to be platform-independent, but some platform and run-time environment specific optimised functions are built-in to maximise performance, and those special optimised routines are need to determine run-time environment for select variant executing path.

This class manages that provides a couple of functions to determine platform information of the run-time environment.

Note

This class is supposed to use by advanced user only.

Member Function Documentation

getCpuIdentifier()

static const String & Ogre::PlatformInformation::getCpuIdentifier ( void  )

static

Gets a string of the CPU identifier.

Note

Actual detecting are performs in the first time call to this function, and then all future calls with return internal cached value.

getCpuFeatures()

static uint Ogre::PlatformInformation::getCpuFeatures ( void  )

static

Gets a or-masked of enum CpuFeatures that are supported by the CPU.

Note

Actual detecting are performs in the first time call to this function, and then all future calls with return internal cached value.

hasCpuFeature()

static bool Ogre::PlatformInformation::hasCpuFeature ( CpuFeatures  feature )

static

Gets whether a specific feature is supported by the CPU.

Note

Actual detecting are performs in the first time call to this function, and then all future calls with return internal cached value.

log()

static void Ogre::PlatformInformation::log ( Log *  pLog )

static

Write the CPU information to the passed in Log.
