## Detailed Description

A helper base class for `cppu::PropertySetMixin`.

See the documentation of `cppu::PropertySetMixin` for further details.

That `cppu::PropertySetMixin` is derived from this base class should be considered an implementation detail. The functionality of `cppu::PropertySetMixin` that is inherited from this base class and is visible to subclasses of `cppu::PropertySetMixin` should be treated by such subclasses as being provided by `cppu::PropertySetMixin` directly (e.g., in such subclasses, use “`PropertySetMixin::Implements`” instead of “`PropertySetMixinImpl::Implements`”).

Since
  UDK 3.2.1

## Member Enumeration Documentation

## ◆ Implements

enum cppu::PropertySetMixinImpl::Implements
| protected

Flags used by subclasses of `cppu::PropertySetMixin` to specify what UNO interface types shall be supported.

Enumerator
IMPLEMENTS_PROPERTY_SET | Flag specifying that the UNO interface type `css::beans::XPropertySet` shall be supported.
IMPLEMENTS_FAST_PROPERTY_SET | Flag specifying that the UNO interface type `css::beans::XFastPropertySet` shall be supported.
IMPLEMENTS_PROPERTY_ACCESS | Flag specifying that the UNO interface type `css::beans::XPropertyAccess` shall be supported.

## Member Function Documentation

## ◆ addPropertyChangeListener()

virtual void cppu::PropertySetMixinImpl::addPropertyChangeListener | ( | rtl::OUString const & | propertyName,
|  | css::uno::Reference< css::beans::XPropertyChangeListener > const & | listener )
| protected virtual

Adds a `css::beans::XPropertyChangeListener`.

If a listener is added more than once, it will receive all relevant notifications multiple times.

See also
  css::beans::XPropertySet::addPropertyChangeListener

## ◆ addVetoableChangeListener()

virtual void cppu::PropertySetMixinImpl::addVetoableChangeListener | ( | rtl::OUString const & | propertyName,
|  | css::uno::Reference< css::beans::XVetoableChangeListener > const & | listener )
| protected virtual

Adds a `css::beans::XVetoableChangeListener`.

If a listener is added more than once, it will receive all relevant notifications multiple times.

See also
  css::beans::XPropertySet::addVetoableChangeListener

## ◆ dispose()

void cppu::PropertySetMixinImpl::dispose | ( |  | ) |
| protected

Mark this instance as being disposed.

See `css::lang::XComponent` for the general concept of disposing UNO objects. On the first call to this function, all registered listeners (`css::beans::XPropertyChangeListener`s and `css::beans::XVetoableChangeListener`s) are notified of the disposing source. Any subsequent calls to this function are ignored.

May throw `css::uno::RuntimeException` and `std::bad_alloc`.

## ◆ getFastPropertyValue()

virtual css::uno::Any cppu::PropertySetMixinImpl::getFastPropertyValue | ( | sal_Int32 | handle | ) |
| protected virtual

## ◆ getPropertySetInfo()

virtual css::uno::Reference< css::beans::XPropertySetInfo > cppu::PropertySetMixinImpl::getPropertySetInfo | ( |  | ) |
| protected virtual

## ◆ getPropertyValue()

virtual css::uno::Any cppu::PropertySetMixinImpl::getPropertyValue | ( | rtl::OUString const & | propertyName | ) |
| protected virtual

## ◆ getPropertyValues()

virtual css::uno::Sequence< css::beans::PropertyValue > cppu::PropertySetMixinImpl::getPropertyValues | ( |  | ) |
| protected virtual

## ◆ prepareSet()

void cppu::PropertySetMixinImpl::prepareSet | ( | rtl::OUString const & | propertyName,
|  | css::uno::Any const & | oldValue,
|  | css::uno::Any const & | newValue,
|  | BoundListeners * | boundListeners )
| protected

A function used by subclasses of `cppu::PropertySetMixin` when implementing UNO interface type attribute setter functions.

First, this function checks whether this instance has already been disposed (see `cppu::PropertySetMixinImpl::dispose`), and throws a `css::lang::DisposedException` if applicable. For a constrained attribute (whose setter can explicitly raise `css::beans::PropertyVetoException`), this function notifies any `css::beans::XVetoableChangeListener`s. For a bound attribute, this function modifies the passed-in `boundListeners` so that it can afterwards be used to notify any `css::beans::XPropertyChangeListener`s. This function should be called before storing the new attribute value, and `boundListeners->notify()` should be called exactly once after storing the new attribute value (in case the attribute is bound; otherwise, calling `boundListeners->notify()` is ignored). Furthermore, `boundListeners->notify()` and this function have to be called from the same thread.

May throw `css::beans::PropertyVetoException`, `css::uno::RuntimeException` (and `css::lang::DisposedException` in particular), and `std::bad_alloc`.

Parameters

  propertyName | the name of the property (which is the same as the name of the attribute that is going to be set)
  oldValue | the property value corresponding to the old attribute value. This is only used as `css::beans::PropertyChangeEvent::OldValue`, which is rather useless, anyway (see “Using the Observer Pattern” in OpenOffice.org Coding Guidelines). If the attribute that is going to be set is neither bound nor constrained, or if `css::beans::PropertyChangeEvent::OldValue` should not be set, a `VOID` `Any` can be used instead.
  newValue | the property value corresponding to the new attribute value. This is only used as `css::beans::PropertyChangeEvent::NewValue`, which is rather useless, anyway (see “Using the Observer Pattern” in OpenOffice.org Coding Guidelines), unless the attribute that is going to be set is constrained. If the attribute that is going to be set is neither bound nor constrained, or if it is only bound but `css::beans::PropertyChangeEvent::NewValue` should not be set, a `VOID` `Any` can be used instead.
  boundListeners | a pointer to a fresh `cppu::PropertySetMixinImpl::BoundListeners` instance (which has not been passed to this function before, and on which `notify` has not yet been called); may only be null if the attribute that is going to be set is not bound

## ◆ queryInterface()

virtual css::uno::Any cppu::PropertySetMixinImpl::queryInterface | ( | css::uno::Type const & | type | ) |
| protected virtual

A function used by subclasses of `cppu::PropertySetMixin` when implementing `css::uno::XInterface::queryInterface`.

This function checks for support of any of the UNO interface types specified in the call of the `cppu::PropertySetMixin` constructor. It does not check for any other UNO interface types (not even for `css::uno::XInterface`), and should not be used directly as the implementation of `css::uno::XInterface::queryInterface` of this UNO object.

## ◆ removePropertyChangeListener()

virtual void cppu::PropertySetMixinImpl::removePropertyChangeListener | ( | rtl::OUString const & | propertyName,
|  | css::uno::Reference< css::beans::XPropertyChangeListener > const & | listener )
| protected virtual

## ◆ removeVetoableChangeListener()

virtual void cppu::PropertySetMixinImpl::removeVetoableChangeListener | ( | rtl::OUString const & | propertyName,
|  | css::uno::Reference< css::beans::XVetoableChangeListener > const & | listener )
| protected virtual

## ◆ setFastPropertyValue()

virtual void cppu::PropertySetMixinImpl::setFastPropertyValue | ( | sal_Int32 | handle,
|  | css::uno::Any const & | value )
| protected virtual

## ◆ setPropertyValue()

virtual void cppu::PropertySetMixinImpl::setPropertyValue | ( | rtl::OUString const & | propertyName,
|  | css::uno::Any const & | value )
| protected virtual

## ◆ setPropertyValues()

virtual void cppu::PropertySetMixinImpl::setPropertyValues | ( | css::uno::Sequence< css::beans::PropertyValue > const & | props | ) |
| protected virtual
