  ArcProperty, AttributeProperty, ToManyMapProperty, ToManyProperty, ToOneProperty

All Known Implementing Classes:

    public interface Property

Defines bean property API used by Cayenne to access object data, do faulting and graph maintenance tasks.

Since:
  1.2

Method Summary
`String` | `getName()` Returns property name.
`void` | `injectValueHolder(Object object)` If a property is implemented as a ValueHolder, this operation would create an unfaulted value holder and inject it into the object, if an object doesn't have it set yet.
`Object` | `readProperty(Object object)` Returns a property value, inflating unresolved object if need.
`Object` | `readPropertyDirectly(Object object)` Returns a property value of an object without disturbing the object fault status.
`boolean` | `visit(PropertyVisitor visitor)` A visitor accept method.
`void` | `writeProperty(Object object, Object oldValue, Object newValue)` Sets a property value, inflating unresolved object if need.
`void` | `writePropertyDirectly(Object object, Object oldValue, Object newValue)` Sets a property value of an object without disturbing the object fault status.

Method Detail

### getName

    String getName()

  Returns property name.

### readPropertyDirectly

    Object readPropertyDirectly(Object object)
                                throws PropertyException

  Returns a property value of an object without disturbing the object fault status.

  Throws:
    `PropertyException`

### readProperty

    Object readProperty(Object object)
                        throws PropertyException

  Returns a property value, inflating unresolved object if need.

  Throws:
    `PropertyException`

### writePropertyDirectly

    void writePropertyDirectly(Object object,
                               Object oldValue,
                               Object newValue)
                               throws PropertyException

  Sets a property value of an object without disturbing the object fault status. Old value of the property is specified as a hint and can be ignored by the property implementor.

  Throws:
    `PropertyException`

### writeProperty

    void writeProperty(Object object,
                       Object oldValue,
                       Object newValue)
                       throws PropertyException

  Sets a property value, inflating unresolved object if need. Old value of the property is specified as a hint and can be ignored by the property implementor.

  Throws:
    `PropertyException`

### visit

    boolean visit(PropertyVisitor visitor)

  A visitor accept method.

  Returns:
    a status returned by the corresponding callback method of the visitor. It serves as an indication of whether peer properties processing is still needed.

### injectValueHolder

    void injectValueHolder(Object object)
                           throws PropertyException

  If a property is implemented as a ValueHolder, this operation would create an unfaulted value holder and inject it into the object, if an object doesn't have it set yet.
