Examples of org.eclipse.core.filesystem.IFileStore

org.eclipse.core.filesystem.IFileStore
A file store is responsible for storage and retrieval of a single file in some file system. The actual protocols and media used for communicating with the file system are abstracted away by this interface, apart from the store's ability to represent itself as a hierarchical {@link java.net.URI}.
File store instances are lightweight handle objects; a store knows how to access and store file information, but does not retain a large memory footprint or operating system connections such as sockets or file handles. The presence of a file store instance does not imply the existence of a corresponding file in the file system represented by that store. A store that has a corresponding file in its file system is said to exist.

As much as possible, implementations of this API maintain the characteristics of the underlying file system represented by this store. For example, store instances will be case-sensitive and case-preserving only when representing case-sensitive and case-preserving file systems.

This interface is not intended to be implemented by clients. File store implementations must subclass {@link FileStore} rather than implementingthis interface directly.
