oshi.software.common.AbstractFileSystem

oshi.software.os.unix.freebsd.FreeBsdFileSystem

All Implemented Interfaces:

FileSystem

public class FreeBsdFileSystem
extends AbstractFileSystem

The Solaris File System contains OSFileStores 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.

Method Details

getFileStores

public OSFileStore[] getFileStores(boolean localOnly)

Description copied from interface: FileSystem

Get file stores on this machine Instantiates an array of OSFileStore 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()

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()

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

public static boolean updateFileStoreStats(OSFileStore osFileStore)

updateFileStoreStats.

Parameters:

osFileStore - a OSFileStore object.

Returns:

a boolean.
