Package oshi.software.os.linux
Class LinuxFileSystem
java.lang.Object
oshi.software.common.AbstractFileSystem
oshi.software.os.linux.LinuxFileSystem
- All Implemented Interfaces:
FileSystem
@ThreadSafe public class LinuxFileSystem extends AbstractFileSystem
The Linux File System contains
OSFileStore
s which
are a storage pool, device, partition, volume, concrete file system or other
implementation specific means of file storage. In Linux, these are found in
the /proc/mount filesystem, excluding temporary and kernel mounts.-

getFileStores
Description copied from interface:FileSystem
Get file stores on this machine Instantiates an array ofOSFileStore
objects, representing a storage pool, device, partition, volume, concrete file system or other implementation specific means of file storage.- Parameters:
localOnly
- If true, filters the list to only local file stores.- Returns:
- An array of OSFileStore objects or an empty array if none are present.
-
getOpenFileDescriptors
public long getOpenFileDescriptors()Description copied from interface:FileSystem
The current number of open file descriptors. A file descriptor is an abstract handle used to access I/O resources such as files and network connections. On UNIX-based systems there is a system-wide limit on the number of open file descriptors. On Windows systems, this method returns the total number of handles held by Processes. While Windows handles are conceptually similar to file descriptors, they may also refer to a number of non-I/O related objects.- Returns:
- The number of open file descriptors if available, 0 otherwise.
-
getMaxFileDescriptors
public long getMaxFileDescriptors()Description copied from interface:FileSystem
The maximum number of open file descriptors. A file descriptor is an abstract handle used to access I/O resources such as files and network connections. On UNIX-based systems there is a system-wide limit on the number of open file descriptors. On Windows systems, this method returns the theoretical max number of handles (2^24-2^15 on 32-bit, 2^24-2^16 on 64-bit). There may be a lower per-process limit. While Windows handles are conceptually similar to file descriptors, they may also refer to a number of non-I/O related objects.- Returns:
- The maximum number of file descriptors if available, 0 otherwise.
-
updateFileStoreStats
updateFileStoreStats.
- Parameters:
osFileStore
- aOSFileStore
object.- Returns:
- a boolean.
