Interface IGorgonFileSystemProviderFactory

A factory object used to create file system provider plug ins.

Namespace: Gorgon.IO.Providers
Assembly: Gorgon.FileSystem.dll
Syntax
public interface IGorgonFileSystemProviderFactory
Remarks

This will generate providers that will allow access to different types of file systems. For example, a user may create a file system provider that will open 7-zip files, but the IGorgonFileSystem will not know how to read those files without the appropriate provider. This object would be used to load that 7-zip provider, and add it to the file system object so that it will know how to mount those file types.

File system providers are plug ins, and should have their assemblies loaded by the GorgonMefPlugInCache before using this method and a IGorgonPlugInService should be created in order to pass it to this factory.

Examples

The following example shows how to use the provider factory:

// In a real world application, you would keep your cache for as long as you need your plug ins.
// Premature disposal can cause errors.
using (GorgonMefPlugInCache cache = new GorgonMefPlugInCache())
{
	// Create the provider factory.
	IGorgonFileSystemProviderFactory factory = new GorgonFileSystemProviderFactory(cache);

	// Get our provider from the factory.
	IGorgonFileSystemProvider provider = CreateProvider(@"C:\FileSystemProviders\Gorgon.FileSystem.7zip.dll", "Gorgon.FileSystem.SevenZipProvider");

	// Mount the file system.
	IGorgonFileSystem fileSystem = new GorgonFileSystem(provider);

	fileSystem.Mount("c:\path\to\your\archive\file.7z");

	// Do stuff...
}
