## Detailed Description

This is the base class for compression filters such as gzip and bzip2.

It's pretty much internal. Don't use directly, use KFilterDev instead.

void KFilterBase::setDevice | ( | QIODevice * | dev,
|  | bool | autodelete = false
| ) |

KFilterBase * KFilterBase::findFilterByFileName | ( | const QString & | fileName | ) | `[static]`

| Call this to create the appropriate filter for the file named `fileName`. Definition at line 42 of file kfilterbase.cpp. References KMimeType::findByPath(), and findFilterByMimeType(). Referenced by KFilterDev::deviceForFile().

KFilterBase * KFilterBase::findFilterByMimeType | ( | const QString & | mimeType | ) | `[static]`
