This extension point is used to provide implementations of the abstract file system API org.eclipse.core.filesystem.IFileSystem. File system implementations control all aspects of querying and modifying a tree of files and directories in some backing store. Each file system extension is responsible for a file system namespace identified by a particular URI scheme. The URI scheme of this kind of file system. The fully qualified name of a class that subclasses org.eclipse.core.filesystem.provider.FileSystem org.eclipse.core.filesystem 1.0 Following is an example of a file system extension that provides access to file systems using the "gopher" URI scheme. <p> <pre> <extension id="gopherFS" name="Gopher File System" point="org.eclipse.core.filesystem.filesystems"> <filesystem scheme="gopher"> <run class="com.xyz.fs.GopherFileSystem"/> </filesystem> </extension> </pre> </p> If this extension was defined in a plug-in with id "com.xyz.coolplugin", the fully qualified name of this file system extension would be "com.xyz.coolplugin.gopherFS". The value of the class attribute must represent a subclass of <samp>org.eclipse.core.filesystem.provider.FileSystem</samp>. <p> File system instances can be obtained via the method <samp>org.eclipse.core.filesystem.FileSystemCore.getFileSystem(String)</samp>. The platform provides a file system implementation for the "file" scheme. Copyright (c) 2005 IBM Corporation and others.<br> All rights reserved.
