CVPlatform Class Reference #include <CVPlatform.h> List of all members. Detailed Description Platform-specific object factory CVPlatform is a singleton class factory for platform-specific classes. This allows us to instantiate totally different objects on different platforms without making the calling code platform-specific or requiring subclassing. When setting up a project for a specific platform, make sure to add in the appropriate CVPlatform*.cpp for that platform. It implements the CVPlatform class for us. Also make sure to include the platform-specific .cpp file for each class we use CVPlatform to create.

GetPlatform() creates the platform object if needed. Definition at line 124 of file CVPlatformWin32.cpp. Referenced by GetPlatform(). CVPlatform::~CVPlatform (   )  [protected, virtual]   CVPlatform destructor - don't delete CVPlatform directly. GetPlatform() registers with the runtime library for deletion when the process exits. Definition at line 134 of file CVPlatformWin32.cpp. Member Function Documentation CVVidCapture * CVPlatform::AcquireVideoCapture (   )    AcquireVideoCapture() acquires a CVVidCapture object appropriate for the current system. Definition at line 96 of file CVPlatformWin32.cpp. Referenced by CVAcquireVidCap(), CVidCapGuiTestDlg::OnInitDialog(), and TestIt(). void CVPlatform::FreePlatform (   )  [static, private]   FreePlatform() frees the static platform object as the process exits. Do not call it directly. It is made to be called from the atexit() handler. Definition at line 146 of file CVPlatformWin32.cpp. References sPlatform. Referenced by GetPlatform(). CVPlatform * CVPlatform::GetPlatform (   )  [static]   GetPlatform() retrieves a pointer to the singleton platform object. Only one instance will be created on the first call. It is automatically freed on exit from the process. Returns: CVPlatform* - pointer to CVPlatform object Definition at line 73 of file CVPlatformWin32.cpp. References CVPlatform(), FreePlatform(), and sPlatform. Referenced by CVAcquireVidCap(), CVReleaseVidCap(), CVidCapGuiTestDlg::OnDestroy(), CVidCapGuiTestDlg::OnInitDialog(), and TestIt(). void CVPlatform::Release (  CVVidCapture *&  vidCap  )    Release() releases an object and sets the pointer to NULL. This version is for video capture objects. Parameters: vidCap  - a CVVidCapture* previously allocated by AcquireVideoCapture().
