BMMExport BMM_IOHandler

(

)

Remarks

Member Function Documentation

BMMExport const MCHAR* ShortDescription

(

const MCHAR *

d = NULL

)

Remarks

Returns the short description string for the IO module, and optionally sets it to d if it is not NULL.

Parameters:

const MCHAR *d = NULL

The short description string to set.

BMMExport const MCHAR* LongDescription

(

const MCHAR *

d = NULL

)

Remarks

Returns the long description string for the IO module, and optionally sets it to d if it is not NULL.

Parameters:

const MCHAR *d = NULL

The long description string to set.

BMMExport const MCHAR* Extension	(	int	index,
		const MCHAR *	e = NULL
	)

Remarks

Returns the specified IO module file name extension, and optionally sets it to e if it is not NULL.

Parameters:

int index

The index of the extension.

const MCHAR *e = NULL

The extension string.

BMMExport int NumExtensions ( )

inline

Remarks

Returns the number of file name extensions for the IO module.

{ return ioExtension.Count(); }

BMMExport void SetCD

(

ClassDesc *

dll

)

This grabs the ClassID and the SuperClassID of Class Descriptor that gets passed in.

It does not grab a hold of the Class Descriptor pointer itself.

Parameters

dll	- A pointer to the class descriptor.

BMMExport ClassDesc* GetCD

(

)

Remarks

Returns the class descriptor for the IO module.

BMMExport void SetDllNumber ( int  num )

inline

{ dllNumber = num; }

BMMExport int GetDllNum ( )

inline

{ return dllNumber; }

BMMExport void SetCapabilities ( DWORD  cap )

inline

Remarks

Sets the capabilities flag for the IO module.

Parameters:

DWORD cap

See BitmapIO Capability Flags.

{ ioCapabilities |= cap;};

BMMExport DWORD GetCapabilities ( )

inline

Remarks

Returns the capabilities flag for the IO module.

Returns

See BitmapIO Capability Flags.

{ return (ioCapabilities);};

BMMExport BOOL TestCapabilities ( DWORD  cap )

inline

Remarks

Tests the capability flags passed.

Parameters:

DWORD cap

See BitmapIO Capability Flags.

Returns

TRUE if the flags were set; otherwise FALSE.

Operators:

{ return ((ioCapabilities& cap) != 0);};

BMMExport BMM_IOHandler& operator=

(

BMM_IOHandler &

from

)

Remarks

Assignment operator.
