void CP_FileSystemSpec_Imp::Set const CP_String inFullpath  )  [inherited]
 

void CP_FileSystemSpec_Imp::SetName const CP_String inFullName  )  [inherited]
 

Sets the file name for this file system spec Will change the file name (file title + file extension) but not the file path or the file drive (volume)

Returns:
void

void CP_FileSystemSpec_Imp::SetName const CP_String inFileName  )  [inherited]
 

void CP_FileSystemSpec_Imp::AssertDecomposedForm  )  const [inherited]
 

Since an FSRef can't point to a non-existing file, file specs for those files must be represented as an FSRef for the parent directory and a string for the node's name.
This functions ensures that the CP_FileSystemSpec in question is represented in that form. This is important to make sure the filespec remains valid after removing a file.

Note:
This function is const, even though it modifies the contents, but since it doesn't change the semantical contents of the object, it's conceptually constant.
Exceptions:
Any OSErr exception may be raised if the filespec is not valid or if the file doesn't exist any more.

FSRef CP_FileSystemSpec_Imp::FSSpecToFSRef const FSSpec &  inFSSpec  )  [protected, inherited]

Parameters:
inFSSpec FSSpec of the object to return FSRef for.
Returns:
FSRef FSRef to the object.

FSSpec CP_FileSystemSpec_Imp::FSRefToFSSpec const FSRef &  inFSRef  )  [protected, inherited]
 

Returns a FSSpec to the file specified in the passed in FSRef. This throws an OSError exception if not successful.

Parameters:
inFSRef FSRef of the object to return FSRef for.
