*/
published interface XComponentLoader: com::sun::star::uno::XInterface
{
/** loads a component specified by a URL into the specified
new or existing frame.
@param URL
specifies the URL of the document to load
<p>
To create new documents, use "private:factory/scalc", "private:factory/swriter", etc.
Other special protocols (e.g. "slot:", ".uno") are not allowed and raise
a com::sun::star::lang::IllegalArgumentException.
</p>
@param TargetFrameName
specifies the name of the frame to view the document in
<p>
If a frame with the specified name already exists, it is used, otherwise it
is created. There exist some special targets which never can be used
as real frame names:
<table border=1>
<tr>
<td><strong>"_blank"</strong></td>
<td>always creates a new frame</td>
</tr>
<tr>
<td><strong>"_default"</strong></td>
<td>special UI functionality<br>(e.g. detecting of already loaded documents, using of empty frames of creating of new top frames as fallback)</td>
</tr>
<tr>
<td><strong>"_self", ""(!)</strong></td>
<td>means frame himself</td>
</tr>
<tr>
<td><strong>"_parent"</strong></td>
<td>address direct parent of frame</td>
</tr>
<tr>
<td><strong>"_top"</strong></td>
<td>indicates top frame of current path in tree</td>
</tr>
<tr>
<td><strong>"_beamer"</strong></td>
<td>means special sub frame</td>
</tr>
</table>
@param SearchFlags
use the values of FrameSearchFlag to specify
how to find the specified <var>TargetFrameName</var>
<p>
Note: These flags are optional ones and will be used for non special
target names only.
</p>
@param Arguments
these arguments specify component or filter specific behavior
<p>
For example, "ReadOnly" with a boolean value specifies whether
the document is opened read-only. "FilterName" specifies the
component type to create and the filter to use, for example:
"Text - CSV". For more information see
com::sun::star::document::MediaDescriptor.
</p>
@return
a com::sun::star::lang::XComponent for successfully loaded
documents or
<br>
`NULL`if it failed
<p>
This interface is a generic one and can be used to start further requests on
loaded document or control the lifetime of it (means dispose() it after using).
The real document service behind this interface can be one of follow three ones:
<ul>
<li>
com::sun::star::awt::XWindow for simple components<br/>
Should be used for viewable components only. It is not allowed to dispose
it after use directly, because the frame containing the component is its owner.
Because the frame object is not accessible through the interface too,
only an interacting user can do this by closing the frame's window.
</li>
<li>
XController for richer components<br/>
Should be used for real editable components which doesn't need a model.
It is not allowed to dispose it after use directly, because the frame
containing the component is its owner. Here the object can be disposed
by disposing the frame, that the XController::getFrame()
method of the controller returns. But for visible components the controller
should be asked for permission by calling XController::suspend() before.
</li>
<li>
XModel for full featured components<br/>
A model that in general can be shared between several view/controller pairs,
does not have an explicit owner. Every view and also the component that
loaded the document may consider itself as an owner.
Simply calling com::sun::star::lang::XComponent::dispose() on this model may
cause problems, if some members of the "owner community" are currently
busy working on the model. These problems are handled by explicit closing
negotiations through the interface com::sun::star::util::XCloseable.
Direct dispose of the model is allowed only, if this special interface doesn't exist.
</li>
</ul>
</p>
@throws com::sun::star::io::IOException
when <var>URL</var> couldn't be found or was corrupt
@throws com::sun::star::lang::IllegalArgumentException
