EventObject

public class EventObject
extends Object implements Serializable

java.lang.Object
↳	java.util.EventObject

Known direct subclasses

ConnectionEvent, HandshakeCompletedEvent, NodeChangeEvent, PreferenceChangeEvent, PropertyChangeEvent, RowSetEvent, SSLSessionBindingEvent, StatementEvent

ConnectionEvent	An `Event` object that provides information about the source of a connection-related event.
HandshakeCompletedEvent	This event indicates that an SSL handshake completed on a given SSL connection.
NodeChangeEvent	An event emitted by a Preferences node to indicate that a child of that node has been added or removed.
PreferenceChangeEvent	An event emitted by a Preferences node to indicate that a preference has been added, removed or has had its value changed.
PropertyChangeEvent	A "PropertyChange" event gets delivered whenever a bean changes a "bound" or "constrained" property.
RowSetEvent	An `Event` object generated when an event occurs to a `RowSet` object.
SSLSessionBindingEvent	This event is propagated to a SSLSessionBindingListener.
StatementEvent	A `StatementEvent` is sent to all `StatementEventListener`s which were registered with a `PooledConnection`.

Known indirect subclasses

IndexedPropertyChangeEvent

IndexedPropertyChangeEvent An "IndexedPropertyChange" event gets delivered whenever a component that conforms to the JavaBeans™ specification (a "bean") changes a bound indexed property.

The root class from which all event state objects shall be derived.

All Events are constructed with a reference to the object, the "source", that is logically deemed to be the object upon which the Event in question initially occurred upon.

Summary

Fields
`protected Object`	`source` The object on which the Event initially occurred.

Public constructors
`EventObject(Object source)` Constructs a prototypical Event.

Public methods
`Object`	`getSource()` The object on which the Event initially occurred.
`String`	`toString()` Returns a String representation of this EventObject.

Inherited methods

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.
