Package org.eclipse.core.filesystem
Interface IFileSystem
- All Superinterfaces:
IAdaptable
- All Known Implementing Classes:
FileSystem
This is the main interface to a single file system. Each file system instance
manages interaction with all files in the backing store represented by a
particular URI scheme.
File systems are registered using the "filesystems" extension point.
- Since:
- org.eclipse.core.filesystem 1.0
- See Also:
- Restriction:
- This interface is not intended to be implemented by clients. File system
implementations must subclass
FileSystemrather than implementing this interface directly.

Method Details
-
attributes
int attributes()Returns the file attributes supported by this file system. This value is a bit mask of theEFS.ATTRIBUTE_*constants.- Returns:
- the file attributes supported by this file system.
-
canDelete
boolean canDelete()Returns whether this file system supports deletion- Returns:
trueif this file system allows deletion of files and directories, andfalseotherwise
-
canWrite
boolean canWrite()Returns whether this file system supports modification.- Returns:
trueif this file system allows modification of files and directories, andfalseotherwise
-
fetchFileTree
Returns a file tree containing information about the complete sub-tree rooted at the given store. Returnsnullif this file system does not support the creation of such file trees.A file tree accurately represents the state of a portion of a file system at the time it is created, but it is never updated. Clients using a file tree must tolerate the fact that the actual file system contents may change after the tree is generated.
- Parameters:
root- The store to use as the root of the file treemonitor- a progress monitor, ornullif progress reporting and cancellation are not desired- Returns:
- an
IFileTreecontaining the sub-tree of the given store, ornull - Throws:
CoreException- if this method fails. Reasons include:- Problems occurred while contacting the file system.

-
fromLocalFile
Returns the file store in this file system corresponding to the given local file. Returnsnullif this file system cannot provide anIFileStorecorresponding to a local file.- Parameters:
file- The file to be converted- Returns:
- The
IFileStorecorresponding to the given file, ornull - See Also:
-
getScheme
String getScheme()Returns the URI scheme of this file system.- Returns:
- the URI scheme of this file system.
-
getStore
Returns a handle to a file store in this file system. This is a handle-only method; this method succeeds regardless of whether a file exists at that path in this file system.This is a convenience method for file systems that do not make use of the authority
URIcomponent, such as a host or user information. The provided path argument is interpreted as the path component of the file system'sURI. For example, this method can be used to safely navigate within the local file system.- Parameters:
path- A path to a file store within the scheme of this file system.- Returns:
- A handle to a file store in this file system
- See Also:
-
getStore
Returns a handle to a file store in this file system. This is a handle-only method; this method succeeds regardless of whether a file exists at that path in this file system. The provided URI must have the appropriate scheme and component parts for the file system on which this method is called.- Parameters:
uri- The URI of the file store to return.- Returns:
- A handle to a file store in this file system
-
isCaseSensitive
boolean isCaseSensitive()Returns whether this file system is case sensitive. A case sensitive file system treats files with names that differ only in case as different files. For example, "HELLO", "Hello", and "hello" would be three different files or directories in a case sensitive file system.- Returns:
trueif this file system is case sensitive, andfalseotherwise.
