50 \brief The PolyUncompressor class is a class for uncompressing |
|
51 compressed files. |
|
52 |
|
53 This subclass of Uncompressor contains a parameterized |
|
54 command for doing the uncompression |
|
55 |
|
56 It has an uncompressFile() function you call to do the |
|
57 actual uncompression. |

|
61 The constructor takes the list of filename \a extensions, |
|
62 which it passes to the base class, and the \a commandFormat, |
|
63 which it stores locally. The \a commandFormat is a command |
|
64 template string. |
