## Detailed Description

### template<class Tbase_set>
class BaseMedia< Tbase_set >

Base for all base media (graphics, sounds).

Template Parameters:

  | Tbase_set | the real set we're going to be

Definition at line 144 of file base_media_base.h.

## Member Function Documentation

template<class Tbase_set >

bool BaseMedia< Tbase_set >::AddFile | ( | const char * | filename,
|  | size_t | basepath_length |
| ) |  |  | `[inline, protected, virtual]`

Add a file with the given filename.

Parameters:

  | filename | the full path to the file to read
  | basepath_length | amount of characters to chop of before to get a filename relative to the search path.

Returns:
  true if the file is added.

Implements FileScanner.

bool BaseMedia< Tbase_set >::DetermineBestSet | ( |  | ) | `[inline, static]`

Determine the graphics pack that has to be used.

The one with the most correct files wins.

Returns:
  true if a best set has been found.

template<class Tbase_set >

const char * BaseMedia< Tbase_set >::GetExtension | ( |  | ) | `[inline, static, protected]`

Get the extension that is used to identify this set.

Returns:
  the extension

template<class Tbase_set >

const Tbase_set * BaseMedia< Tbase_set >::GetSet | ( | int | index | ) | `[inline, static]`

Get the name of the graphics set at the specified index.

Returns:
  the name of the set

template<class Tbase_set >

char * BaseMedia< Tbase_set >::GetSetsList | ( | char * | p,
|  | const char * | last |
| ) |  |  | `[inline, static]`

Returns a list with the sets.

Parameters:

  | p | where to print to

template<class Tbase_set >

bool BaseMedia< Tbase_set >::HasSet | ( | const ContentInfo * | ci,
|  | bool | md5sum |
| ) |  |  | `[inline, static]`

Check whether we have an set with the exact characteristics as ci.

Parameters:

  | ci | the characteristics to search on (shortname and md5sum)
  | md5sum | whether to check the MD5 checksum

Returns:
  true iff we have an set matching.
