Class Binding<SS,SV,TS,TV>

java.lang.Object
org.jdesktop.beansbinding.Binding<SS,SV,TS,TV>
Type Parameters:
SS - the type of source object
SV - the type of value that the source property represents
TS - the type of target object
TV - the type of value that the target property represents
Direct Known Subclasses:
AbstractColumnBinding, AutoBinding
public abstract class Binding<SS,SV,TS,TV> extends Object
Binding is an abstract class that represents the concept of a binding between two properties, typically of two objects, and contains methods for explicitly syncing the values of the two properties. Binding itself does no automatic syncing between property values. Subclasses will typically keep the values in sync according to some strategy.

Some Bindings are managed, often by another Binding. A managed Binding does not allow certain methods to be called by the user. These methods are identified in their documentation. Subclasses should call setManaged(true) to make themselves managed. Binding provides protected versions of the managed methods with the suffix "Unmanaged" for subclasses to use internally without checking whether or not they are managed.

Any PropertyResolutionExceptions thrown by Property objects used by this binding are allowed to flow through to the caller of the Binding methods.

    • setSourceUnreadableValue

      public final void setSourceUnreadableValue(TV sourceUnreadableValue)
      Sets the value to be returned by getSourceValueForTarget() when the source property is unreadable for the source object. Calling this method stores the given value and indicates that getSourceValueForTarget should use it, by setting the sourceUnreadableValueSet property to true.

      By default, the sourceUnreadableValue property is unset, indicated by the sourceUnreadableValueSet property being false.

      Setting this property to null acts the same as setting it to any other value. To return the property to the unset state (clearing the value and setting sourceUnreadableValueSet back to false) call unsetSourceUnreadableValue().

      If this property was previously unset, this method fires a property change notification with property name "sourceUnreadableValueSet". For all invocations, it also fires a property change notification with property name "sourceUnreadableValue", if necessary, to indicate a change in the property value. If previously unset, the event will indicate an old value of null.

      This method may not be called on a bound binding.

      Parameters:
      sourceUnreadableValue - the value, which may be null
      Throws:
      IllegalStateException - if the Binding is bound
      See Also:

    • unsetSourceUnreadableValue

      public final void unsetSourceUnreadableValue()
      Unsets the value of the sourceUnreadableValue property by clearing the value and setting the value of the sourceUnreadableValueSet property to false.

      If the property was previously set, fires a property change notification with property name "sourceUnreadableValueSet", and a property change notification with property name "sourceUnreadableValue". The event for the latter notification will have a new value of null.

      See the documentation for setSourceUnreadableValue(TV) for more information on the sourceUnreadableValue property.

      This method may not be called on a bound binding.

      Throws:
      IllegalStateException - if the Binding is bound
      See Also:

    • addBindingListener

      public final void addBindingListener(BindingListener listener)
      Adds a BindingListener to be notified of changes to this Binding. Does nothing if the listener is null. If a listener is added more than once, notifications are sent to that listener once for every time that it has been added. The ordering of listener notification is unspecified.
      Parameters:
      listener - the listener to add

    • removeBindingListener

      public final void removeBindingListener(BindingListener listener)
      Removes a BindingListener from the Binding. Does nothing if the listener is null or is not one of those registered. If the listener being removed was registered more than once, only one occurrence of the listener is removed from the list of listeners. The ordering of listener notification is unspecified.
      Parameters:
      listener - the listener to remove
      See Also:

    • getBindingListeners

      public final BindingListener[] getBindingListeners()
      Returns the list of BindingListeners registered on this Binding. Order is undefined. Returns an empty array if there are no listeners.
      Returns:
      the list of BindingListeners registered on this Binding
      See Also:

    • getSourceValueForTarget

      public final Binding.ValueResult<TV> getSourceValueForTarget()
      Fetches the value of the source property for the source object and returns a ValueResult representing that value in terms that can be set on the target property for the target object.

      First, if the target property is not writeable for the target object, a ValueResult is returned representing a failure with failure type SyncFailureType.TARGET_UNWRITEABLE. Then, if the source property is unreadable for the source object, the value of isSourceUnreadableValueSet() is checked. If true then a ValueResult is returned containing the value of the Binding's getSourceUnreadableValue(). Otherwise a ValueResult is returned representing a failure with failure type SyncFailureType.SOURCE_UNREADABLE.

      Next, the value of the source property is fetched for the source object. If the value is null, a ValueResult is returned containing the value of the Binding's getSourceNullValue(). If the value is non-null, the Binding's Converter, if any, is run to convert the value from source type to the target property's getWriteType, by calling its convertForward method with the value. If no Converter is registered, a set of default converters is checked to see if one of them can convert the value to the target type. Finally, the value (converted or not) is cast to the target write type.

      This final value is returned in a ValueResult.

      Any RuntimeException or ClassCastException thrown by a converter or the final cast is propogated up to the caller of this method.

      Returns:
      a ValueResult as described above
      Throws:
      RuntimeException - if thrown by any of the converters
      ClassCastException - if thrown by a converter or the final cast

    • getTargetValueForSource

      public final Binding.ValueResult<SV> getTargetValueForSource()
      Fetches the value of the target property for the target object and returns a ValueResult representing that value in terms that can be set on the source property for the source object.

      First, if the source property is not writeable for the source object, a ValueResult is returned representing a failure with failure type SyncFailureType.SOURCE_UNWRITEABLE. Then, if the target property is not readable for the target object, a ValueResult is returned representing a failure with failure type SyncFailureType.TARGET_UNREADABLE.

      Next, the value of the target property is fetched for the target object. If the value is null, a ValueResult is returned containing the value of the Binding's getTargetNullValue(). If the value is non-null, the Binding's Converter, if any, is run to convert the value from target type to the source property's getWriteType, by calling its convertReverse method with the value. If no Converter is registered, a set of default converters is checked to see if one of them can convert the value to the source type. Finally, the value (converted or not) is cast to the source write type.

      If a converter throws a RuntimeException other than ClassCastException, this method returns a ValueResult containing the failure, with failure type SyncFailureType.CONVERSION_FAILURE.

      As the last step, the Binding's Validator, if any, is called upon to validate the final value. If the Validator returns non-null from its validate method, a ValueResult is returned containing the validation result, with failure type SyncFailureType.VALIDATION_FAILURE. Otherwise a ValueResult is returned containing the final validated value.

      Any ClassCastException thrown by a converter or the final cast is propogated up to the caller of this method.

      Returns:
      a ValueResult as described above
      Throws:
      ClassCastException - if thrown by a converter or the final cast

      Binding fires property change notification for the following properties:

      • sourceProperty
      • targetProperty
      • sourceObject
      • targetObject
      • validator
      • converter
      • sourceNullValue
      • targetNullValue
      • sourceUnreadableValueSet
      • sourceUnreadableValue
      • bound

      For other types of Binding notifications register a BindingListener.

      Parameters:
      listener - the listener to add
