Class WindowsFileSystem

java.lang.Object

org.aoju.bus.health.software.windows.WindowsFileSystem

All Implemented Interfaces:

FileSystem

public class WindowsFileSystem
extends Object
implements FileSystem

The Windows File System contains OSFileStores which are a storage pool, device, partition, volume, concrete file system or other implementation specific means of file storage. In Windows, these are represented by a drive letter, e.g., "A:\" and "C:\"

Since:

JDK 1.8+

Version:

5.5.0

Constructor Detail

WindowsFileSystem

public WindowsFileSystem()

Constructor for WindowsFileSystem.

Method Detail

updateFileStoreStats

public static boolean updateFileStoreStats(OSFileStore osFileStore)

updateFileStoreStats.

Parameters:

osFileStore - a OSFileStore object.

Returns:

a boolean.

getFileStores

public OSFileStore[] getFileStores()

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.

Gets File System Information.

Specified by:

getFileStores in interface FileSystem

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.

Specified by:

getOpenFileDescriptors in interface FileSystem

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.

Specified by:

getMaxFileDescriptors in interface FileSystem

Returns:

The maximum number of file descriptors if available, 0 otherwise.
