short events
The events we're interested in. POLLIN corresponds to being in select(2)'s read fd set, POLLOUT to the write fd set.
Object userData
A non-standard extension that lets callers conveniently map back to the object their fd belongs to. This is used by Selector, for example, to associate each FileDescriptor with the corresponding SelectionKey.
String toString ()
Returns a string representation of the object. In general, the
toString method returns a string that
"textually represents" this object. The result should
be a concise but informative representation that is easy for a
person to read.
It is recommended that all subclasses override this method.
The toString method for class Object
returns a string consisting of the name of the class of which the
object is an instance, the at-sign character `@', and
the unsigned hexadecimal representation of the hash code of the
object. In other words, this method returns a string equal to the
value of:
getClass().getName() + '@' + Integer.toHexString(hashCode())
