Package oshi.software.os.windows
Class WindowsFileSystem
java.lang.Object
oshi.software.common.AbstractFileSystem
oshi.software.os.windows.WindowsFileSystem
- All Implemented Interfaces:
FileSystem
The Windows 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 Windows, these are
represented by a drive letter, e.g., "A:\" and "C:\"-

getFileStores
Description copied from interface:FileSystem
Get file stores on this machine Instantiates a list 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:
- A list of
OSFileStore
objects or an empty array if none are present.
-
getLocalVolumes
Package private method for getting all mounted local drives.- Parameters:
volumeToMatch
- an optional string to filter match, null otherwise- Returns:
- A list of
OSFileStore
objects representing all local mounted volumes
-
getWmiVolumes
Package private method for getting logical drives listed in WMI.- Parameters:
nameToMatch
- an optional string to filter match, null otherwiselocalOnly
- Whether to only search local drives- Returns:
- A list of
OSFileStore
objects representing all network mounted volumes
-
getDriveType
Private method for getting mounted drive type.- Parameters:
drive
- Mounted drive- Returns:
- A drive type description
-
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.
-
getMaxFileDescriptorsPerProcess
public long getMaxFileDescriptorsPerProcess()Description copied from interface:FileSystem
The maximum number of open file descriptors per process. This returns the upper limit which applies to each process. The actual limit of a process may be lower if configured.- Returns:
- The maximum number of file descriptors of each process if available, 0 otherwise.
