Constructor Detail

FileSystemImpl

public FileSystemImpl(FileSystem fileSystem)

Creates a new platform-specific FileSystem object wrapping the provided argument

Parameters:

fileSystem - a platform-specific FileSystem object

Method Detail

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.

Specified by:

getFileStores in interface FileSystem

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 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.

Specified by:

getOpenFileDescriptors in interface FileSystem

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 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.

Specified by:

getMaxFileDescriptors in interface FileSystem

Returns:

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

toJSON

public javax.json.JsonObject toJSON(Properties properties)

Returns this object as a JsonObject. The provided properties will be set on this object to configure the type of information returned using this and future invocations of OshiJsonObject.toJSON().

Specified by:

toJSON in interface OshiJsonObject

Parameters:

properties - Properties to configure returned results

Returns:

a JsonObject for this class.
