Detailed Description

Class MNMesh.

Description:

This is a handy class to subclass off of when you're designing a class with flags. It contains one private data member, a DWORD, with the flag info. It then implements a bunch of handy flag-related functions. All methods of this class are implemented by the system.

Data Members:

private:

DWORD FlagUserFlags;

Stores the flags.

Constructor & Destructor Documentation

FlagUser() [1/3]

FlagUser ( )

Remarks

Constructor. Sets FlagUserFlags to 0, clearing all flag bits.

SetFlag()

void SetFlag ( DWORD  fl, bool  val = TRUE  )

inline

Remarks

Sets flags. Each bit that is set in fl is assigned the value val.

    {
        if (val)
            FlagUserFlags |= fl;
        else
            FlagUserFlags -= (FlagUserFlags & fl);
    }

ClearFlag()

void ClearFlag ( DWORD  fl )

inline

Remarks

Clears flags. Each bit that is set in fl is cleared.

    {
        FlagUserFlags -= (FlagUserFlags & fl);
    }

GetFlag()

bool GetFlag ( DWORD  fl ) const

inline

Remarks

Checks if flags are set.

Returns

TRUE if any of the bits set in fl are set in this FlagUser. FALSE if none of them are.

    {
        return bool(FlagUserFlags & fl);
    }

ClearAllFlags()

void ClearAllFlags ( )

inline

Remarks

Sets FlagUserFlags to 0, clearing all flag bits.

    {
        FlagUserFlags = 0;
    }

void CopyFlags ( DWORD  fl )

inline

Remarks

Copies all flag bits over from fl.

    {
        FlagUserFlags = fl;
    }

CopyFlags() [2/6]

void CopyFlags ( const FlagUser &  fu )

inline

Remarks

Copies all flag bits over from fu.

    {
        FlagUserFlags = fu.FlagUserFlags;
    }

CopyFlags() [3/6]

void CopyFlags ( const FlagUser *  fu )

inline

Remarks

Copies all flag bits over from *fu.

    {

    }

CopyFlags() [4/6]

void CopyFlags ( DWORD  fl, DWORD  mask  )
