Class MacFileSystemJNA

java.lang.Object
oshi.software.common.AbstractFileSystem
oshi.software.common.os.mac.MacFileSystem
oshi.software.os.mac.MacFileSystemJNA
All Implemented Interfaces:
FileSystem
@ThreadSafe public class MacFileSystemJNA extends MacFileSystem
The Mac File System contains OSFileStores which are a storage pool, device, partition, volume, concrete file system or other implementation specific means of file storage. In macOS, these are found in the /Volumes directory.

  • Method Details

    • getFileStores

      public List<OSFileStore> getFileStores(boolean localOnly)
      Description copied from interface: FileSystem
      Get file stores on this machine Instantiates a list 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. On Windows, also excluded CD-ROM drives.
      Returns:
      A list 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.

    • 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.
