|
|
* class ALOpenInputFile
|
|
*
|
|
* DESCRIPTION
|
|
*
|
|
* This class is used to expand wild card specifications on a DOS
|
|
* or NT file system. Note that you can do exciting things with this, like
|
|
* traversing through subdirectories, and separate various specs using
|
|
* commas or white space.
|
|
*
|
|
* DATA MEMBERS
|
|
*
|
|
* mState : The current state of the expander. This is a value
|
|
* from ALExpander state that lets use keep track
|
|
* of where we are between calls to the expander.
|
|
*
|
|
* mpNextExpander : If we are traversing subdirectories, we will
|
|
* open a new expander for each subdirectory. This
|
|
* is a pointer to any subdirectory we might already
|
|
* have open for a search in progress.
|
|
*
|
|
* mInputLine : The list of wildcard filespecs passed in as an
|
|
* argument. This gets whittled away, and will be
|
|
* smaller and smaller as all the names are parsed out.
|
|
*
|
|
* mFullWildName : The current wild card file spec that is being
|
|
* expanded.
|
|
*
|
|
* mWildNameOnly : The current wild name that is being expanded,
|
|
* stripped of its drive and path information.
|
|
*
|
|
* mWildPathOnly : The current drive and path being expanded, stripped
|
|
* of its filename and extension.
|
|
*
|
|
* mResultFileName : The file name that is returned to the calling
|
|
* program.
|
|
*
|
|
* mFindFileData : Under Win32s, this holds data about the file we
|
|
* found.
|
|
*
|
|
* mFindFileHandle : Under Win32s, this is a handle used during the
|
|
* wildcard expansion.
|
|
*
|
|
* mpFfblk : Under MS-DOS, this structure holds the state of
|
|
* the wildcard expansion in progress.
|
|
*
|
|
* miTraverseFlag : This flag indicates whether the search should traverse
|
|
* traverse through subdirectories or just search
|
|
* in the current directory.
|
|
*
|
|
* mCase : Indicates whether file names should always be forced
|
|
* to upper case, forced to lower case, or left mixed.
|
|
*
|
|
* MEMBER FUNCTIONS
|
|
*
|
|
* ALWildCardExpander() : Constructor, everything we need to know to
|
|
* perform the search is defined here.
|
|
* ~ALWildCardExpander() : Destructor.
|
|
* operator new() : Memory allocation function, used when the
|
|
* library is in a DLL.
|
|
* GetNextWildName() : Protected routine to get the next wild name
|
|
* from the input line.
|
|
* GetNextFile() : The function to get the next expanded file
|
|
* name. It keeps chunking out names until
|
|
* the search is complete.
