Method Detail

getFileStores

OSFileStore[] getFileStores()

Get file stores on this machine

Returns:

Array of OSFileStore objects

getOpenFileDescriptors

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 0. While Windows handles are conceptually similar to file descriptors, they may also refer to a number of non-I/O related objects, and there does not appear to be a system-wide limit for open handles.

Returns:

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

getMaxFileDescriptors

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 0. While Windows handles are conceptually similar to file descriptors, they may also refer to a number of non-I/O related objects, and there does not appear to be a system-wide limit for open handles.

Returns:

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