@short A function used by subclasses of

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

|
|

|
|
<code>com::sun::star::beans::PropertyVetoException</code>,

|
|
<code>com::sun::star::lang::DisposedException</code> in particular), and
|
|
<code>std::bad_alloc</code>.
|
|
|
|
@param propertyName the name of the property (which is the same as the
|
|
name of the attribute that is going to be set)
|
|
|
|
@param oldValue the property value corresponding to the old attribute
|
|
value. This is only used as
|
|
<code>com::sun::star::beans::PropertyChangeEvent::OldValue</code>, which
|
|
is rather useless, anyway (see “Using the Observer Pattern”
|
|
in <a href="http://tools.openoffice.org/CodingGuidelines.sxw">
|
|
OpenOffice.org Coding Guidelines</a>). If the attribute
|
|
that is going to be set is neither bound nor constrained, or if
|
|
<code>com::sun::star::beans::PropertyChangeEvent::OldValue</code> should
|
|
not be set, a <code>VOID</code> <code>Any</code> can be used instead.
|
|
|
|
@param newValue the property value corresponding to the new

|
attribute value. This is only used as

<code>com::sun::star::beans::PropertyChangeEvent::NewValue</code>, which

|
is rather useless, anyway (see “Using the Observer Pattern”

|
in <a href="http://tools.openoffice.org/CodingGuidelines.sxw">

OpenOffice.org Coding Guidelines</a>), <em>unless</em> the

that is going to be set is neither bound nor constrained, or if it is
|
|
only bound but
|
|
<code>com::sun::star::beans::PropertyChangeEvent::NewValue</code> should
|
|
not be set, a <code>VOID</code> <code>Any</code> can be used instead.
|
|
|
|
@param boundListeners a pointer to a fresh
|
|
<code>cppu::PropertySetMixinImpl::BoundListeners</code> instance
|
|
(which has not been passed to this function before, and on which
|
|
<code>notify</code> has not yet been called); may only be null if the
