| Packages that use FileDescriptor | |
|---|---|
| java.io | Provides for system input and output through data streams, serialization and the file system. | 
| java.lang | Provides classes that are fundamental to the design of the Java programming language. | 
| java.net | Provides the classes for implementing networking applications. | 
| Uses of FileDescriptor in java.io | 
|---|
| Fields in java.io declared as FileDescriptor | |
|---|---|
| static FileDescriptor | FileDescriptor.errA handle to the standard error stream. | 
| static FileDescriptor | FileDescriptor.inA handle to the standard input stream. | 
| static FileDescriptor | FileDescriptor.outA handle to the standard output stream. | 
| Methods in java.io that return FileDescriptor | |
|---|---|
|  FileDescriptor | RandomAccessFile.getFD()Returns the opaque file descriptor object associated with this stream. | 
|  FileDescriptor | FileOutputStream.getFD()Returns the file descriptor associated with this stream. | 
|  FileDescriptor | FileInputStream.getFD()Returns the FileDescriptorobject  that represents the connection to
 the actual file in the file system being
 used by thisFileInputStream. | 
| Constructors in java.io with parameters of type FileDescriptor | |
|---|---|
| FileInputStream(FileDescriptor fdObj)Creates a FileInputStreamby using the file descriptorfdObj, which represents an existing connection to an
 actual file in the file system. | |
| FileOutputStream(FileDescriptor fdObj)Creates an output file stream to write to the specified file descriptor, which represents an existing connection to an actual file in the file system. | |
| FileReader(FileDescriptor fd)Creates a new FileReader, given the FileDescriptor to read from. | |
| FileWriter(FileDescriptor fd)Constructs a FileWriter object associated with a file descriptor. | |
| Uses of FileDescriptor in java.lang | 
|---|
| Methods in java.lang with parameters of type FileDescriptor | |
|---|---|
|  void | SecurityManager.checkRead(FileDescriptor fd)Throws a SecurityExceptionif the 
 calling thread is not allowed to read from the specified file 
 descriptor. | 
|  void | SecurityManager.checkWrite(FileDescriptor fd)Throws a SecurityExceptionif the 
 calling thread is not allowed to write to the specified file 
 descriptor. | 
| Uses of FileDescriptor in java.net | 
|---|
| Fields in java.net declared as FileDescriptor | |
|---|---|
| protected  FileDescriptor | SocketImpl.fdThe file descriptor object for this socket. | 
| protected  FileDescriptor | DatagramSocketImpl.fdThe file descriptor object. | 
| Methods in java.net that return FileDescriptor | |
|---|---|
| protected  FileDescriptor | SocketImpl.getFileDescriptor()Returns the value of this socket's fdfield. | 
| protected  FileDescriptor | DatagramSocketImpl.getFileDescriptor()Gets the datagram socket file descriptor. |
