/** An interaction request handler that lets the user handle requests via GUI dialogs.
<p>The interaction handler service has a number of <a href="#built_in_handler">built-in handlers</a>, responsible
for a lot of well known interactions. Additionally, there's a configuration module which allows to
<a href="#configuring_handlers">configure additional handlers</a>, responsible for arbitrary requests.</a></p>
<a name="built_in_handler"></a>
<h3>Built-in Handlers</h3>
The following well-known requests can be dealt with by the built-in handlers:
<UL>
<LI><type scope="com::sun::star::ucb">AuthenticationRequest</type></LI>
<LI><type scope="com::sun::star::ucb">CertificateValidationRequest</type></LI>
<LI><type scope="com::sun::star::sync2">BadPartnershipException</type>*</LI>
<LI><type scope="com::sun::star::ucb">HandleCookiesRequest</type></LI>
<LI><type scope="com::sun::star::ucb">InteractiveAugmentedIOException</type>*</LI>
<LI><type scope="com::sun::star::ucb">InteractiveCHAOSException</type>*</LI>
<LI><type scope="com::sun::star::ucb">InteractiveFileIOException</type>*</LI>
<LI><type scope="com::sun::star::ucb">InteractiveIOException</type>*</LI>
<LI><type scope="com::sun::star::ucb">InteractiveNetworkConnectException</type>*</LI>
<LI><type scope="com::sun::star::ucb">InteractiveNetworkException</type>*</LI>
<LI><type scope="com::sun::star::ucb">InteractiveNetworkGeneralException</type>*</LI>
<LI><type scope="com::sun::star::ucb">InteractiveNetworkOffLineException</type>*</LI>
<LI><type scope="com::sun::star::ucb">InteractiveNetworkReadException</type>*</LI>
<LI><type scope="com::sun::star::ucb">InteractiveNetworkResolveNameException</type>*</LI>
<LI><type scope="com::sun::star::ucb">InteractiveNetworkWriteException</type>*</LI>
<LI><type scope="com::sun::star::ucb">InteractiveWrongMediumException</type>*</LI>
<LI><type scope="com::sun::star::task">PasswordRequest</type></LI>
<LI><type scope="com::sun::star::java">WrongJavaVersionException</type>*</LI>
<LI><type scope="com::sun::star::task">DocumentMacroConfirmationRequest</type></LI>
</UL>
The requests marked with an asterisk are only handled if (a) their
continuations match certain restrictions (see below), and (b) the
necessary resource strings are available (this can be exploited by
applications that carry only a subset of all resource files with
them).</P>
<P>The continuation restrictions are as follows: Let <VAR>C</VAR> be the
subset of the provided continuations that are of type
<type scope="com::sun::star::task">XInteractionApprove</type>,
<type scope="com::sun::star::task">XInteractionDisapprove</type>,
<type scope="com::sun::star::task">XInteractionRetry</type>, or
<type scope="com::sun::star::task">XInteractionAbort</type> (or of a
derived type). All other continuations are ignored for these requests.
The request is only handled if the set <VAR>C</VAR> is any of the
following:
<UL>
<LI>Abort</LI>
<LI>Retry, Abort</LI>
<LI>Approve</LI>
<LI>Approve, Abort</LI>
<LI>Approve, Disapprove</LI>
<LI>Approve, Disapprove, Abort</LI>
</UL></P>
<P>An
<type scope="com::sun::star::ucb">InteractiveAugmentedIOException</type>
carries with it a sequence of arguments, which should be
<type scope="com::sun::star::beans">PropertyValue</type>s. The following
details which properties are interpreted by the interaction handler,
depending on the request's
<type scope="com::sun::star::ucb">IOErrorCode</type>:
<DL>
<DT><code>"Uri"</code></DT>
<DD>All error codes except
<const scope="com::sun::star::ucb">IOErrorCode::DIFFERENT_DEVICES</const>.
The URI of the involved resource (a <atom>string</atom>).</DD>
<DT><code>"ResourceName"</code></DT>
<DD>All error codes except
<const scope="com::sun::star::ucb">IOErrorCode::DIFFERENT_DEVICES</const>.
A name for the involved resource (a <atom>string</atom>) that might be
more meaningful to the user than the URI. For example, a
(platform-dependent) path notation for file system resources.</DD>
<DT><code>"ResourceType"</code></DT>
<DD><const scope="com::sun::star::ucb">IOErrorCode::DEVICE_NOT_READY</const>
and
<const scope="com::sun::star::ucb">IOErrorCode::NOT_EXISTING</const>
only. An identifier for the type of resource involved (a
<atom>string</atom>). Currently understood values are
<code>"volume"</code> (e.g., a file system volume) and
<code>"folder"</code> (i.e., a resource that contains other
resources).</DD>
<DT><code>"Removable"</code></DT>
<DD><const scope="com::sun::star::ucb">IOErrorCode::NOT_EXISTING</const>
only. A flag indicating whether the resource resides on a storage
medium that can be removed by the user (a <atom>boolean</atom>).</DD>
<DT><code>"Folder"</code></DT>
<DD><const scope="com::sun::star::ucb">IOErrorCode::CANT_CREATE</const>
only. The name of the folder in which a resource cannot be created (a
<atom>string</atom>).</DD>
<DT><code>"Volume"</code> and <code>"OtherVolume"</code></DT>
<DD><const scope="com::sun::star::ucb">IOErrorCode::DIFFERENT_DEVICES</const>
only. The names of the two volumes involved (two
<atom>string</atom>s).</DD>
</DL></P>
<a name="configuring_handlers"></a>
<h3>Configuring additional Handlers</h3>
<p>It is possible to configure additional interaction handlers, to which certain requests can be delegated. The
configuration node <code>/org.openoffice.Interaction/InteractionHandlers</code> is evaluated and respected
by the <code>InteractionHandler</code> implementation.</p>
<p>A custom interaction handler can declare itself responsible for an arbitrary number of UNO types, specified
by full-qualified type name. Also, for each type, it can specify whether it is responsible for only this particular
type, or all possibly existent derived types.</p>
<p>Whenever the <code>InteractionHandler</code> encounters a request it cannot fulfill itself, it will examine
the configuration, to find a handler implementation for the request, and delegate it to the first matching
handler.</p>
<p>If multiple custom interaction handlers declare themselves responsible for the same request type, it is not
defined which handler will actually be invoked. Thus, when deploying a custom interaction handler, ensure
that the types you specify are general enough to cover all requests you want to handle, but also specific
enough to not cover requests which other handlers might be interested in.</p>
