PropertyChangeEvent

open class PropertyChangeEvent : EventObject
kotlin.Any
   ↳ java.util.EventObject
   ↳ java.beans.PropertyChangeEvent

A "PropertyChange" event gets delivered whenever a bean changes a "bound" or "constrained" property. A PropertyChangeEvent object is sent as an argument to the PropertyChangeListener and VetoableChangeListener methods.

Normally PropertyChangeEvents are accompanied by the name and the old and new value of the changed property. If the new value is a primitive type (such as int or boolean) it must be wrapped as the corresponding java.lang.* Object type (such as Integer or Boolean).

Null values may be provided for the old and the new values if their true values are not known.

An event source may send a null object as the name to indicate that an arbitrary set of if its properties have changed. In this case the old and new values should also be null.

PropertyChangeEvent

Added in API level 3
PropertyChangeEvent(
    source: Any!,
    propertyName: String!,
    oldValue: Any!,
    newValue: Any!)

Constructs a new PropertyChangeEvent.

Parameters
source Any!: the bean that fired the event
propertyName String!: the programmatic name of the property that was changed
oldValue Any!: the old value of the property
newValue Any!: the new value of the property
Exceptions
java.lang.IllegalArgumentException if source is null

Public methods

getNewValue

Added in API level 3
open fun getNewValue(): Any!

Gets the new value for the property, expressed as an Object.

Return
Any! The new value for the property, expressed as an Object. May be null if multiple properties have changed.

getOldValue

Added in API level 3
open fun getOldValue(): Any!

Gets the old value for the property, expressed as an Object.

Return
Any! The old value for the property, expressed as an Object. May be null if multiple properties have changed.

getPropagationId

Added in API level 3
open fun getPropagationId(): Any!

The "propagationId" field is reserved for future use. In Beans 1.0 the sole requirement is that if a listener catches a PropertyChangeEvent and then fires a PropertyChangeEvent of its own, then it should make sure that it propagates the propagationId field from its incoming event to its outgoing event.

Return
Any! the propagationId object associated with a bound/constrained property update.

getPropertyName

Added in API level 3
open fun getPropertyName(): String!

Gets the programmatic name of the property that was changed.

Return
String! The programmatic name of the property that was changed. May be null if multiple properties have changed.

setPropagationId

Added in API level 3
open fun setPropagationId(propagationId: Any!): Unit

Sets the propagationId object for the event.

Parameters
propagationId Any!: The propagationId object for the event.

toString

Added in API level 3
open fun toString(): String

Returns a string representation of the object.

Return
String a string representation of the object
