Detailed Description

Baseclass for a meta info plugin. If you want to write your own plugin, you need to derive from this class.

In your plugin, you need to create a factory for the KFilePlugin

Example:

 typedef KGenericFactory MyFactory;
 K_EXPORT_COMPONENT_FACTORY(kfile_foo, MyFactory("kfile_foo"));

and then just overwrite the methods your plugin supports. If your plugin can only read data, it is sufficient to only write a readInfo() method. If you also want to support changing data and writing it back into the file, you usually need all methods.

[virtual]

[pure virtual]

Read the info from the file in this method and insert it into the provided KFileMetaInfo object. You can get the path to the file with info.path()

[const virtual]

Similar to the above method, but for writing the info back to the file. If you don't have any writable keys, don't implement this method

[const virtual]

This method should create an appropriate validator for the specified item if it's editable or return a null pointer if not. If you don't have any editable items, you don't need this method.

If you you don't need any validation, e.g. you accept any input, you can simply return 0L, or not reimplement this method at all.
