FileDescriptor

Class Overview

The lowest-level representation of a file, device, or socket. If is often used for wrapping an operating system "handle". Some I/O classes can be queried for the FileDescriptor they are operating on, and this descriptor can subsequently be used during the instantiation of another I/O class, so that the new object will reuse it.

The FileDescriptor class also contains static fields representing the system's standard input, output and error streams. These can be used directly if desired, but it is recommended to go through System.in, System.out, and System.err streams respectively.

Applications should not create new FileDescriptors.

[Expand] Inherited Methods

From class java.lang.Object Object clone() Creates and returns a copy of this Object. boolean equals(Object o) Compares this instance with the specified object and indicates if they are equal. void finalize() Is called before the object's memory is being reclaimed by the VM. final Class<? extends Object> getClass() Returns the unique instance of Class which represents this object's class. int hashCode() Returns an integer hash code for this object. final void notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up. final void notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up. String toString() Returns a string containing a concise, human-readable description of this object. final void wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires. final void wait(long millis) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires. final void wait() Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object.
