<p>Welcome to InstantObjects, the integrated framework for developing object-oriented business solutions in Delphi (from Delphi 10.1 to latest version)</p>
<p><img src="./docs/SupportingDelphi.jpg" alt="Support Delphi" /></p>
<p><a href="https://www.embarcadero.com/">www.embarcadero.com</a> - <a href="https://learndelphi.org/">learndelphi.org</a></p>
<h2 id="what-is-instantobjects">What is InstantObjects</h2>
<p>InstantObjects is a RAD technology that enables creation of applications based on persistent business objects. It simplifies the process of realizing ideas into products; shortens time-to-market, and helps keep business focus.</p>
<p>Even though it is still a bolted-on technology, InstantObjects integrates with the Delphi IDE and Object Pascal in a simple, flexible and intuitive manner. There are no sophisticated environments that have to be comprehended before application development can begin.</p>
<p><strong>InstantObjects offers:</strong></p>
<ol>
<li>Model realization in the Delphi IDE via integrated two-way tools (from editor to code)</li>
<li>Object persistence in the most common relational databases or flat XML-based files (also with FireDAC Broker)</li>
<li>Object presentation via standard data-aware controls.</li>
<li>Serialization/Deserialization of object using <a href="https://github.com/paolo-rossi/delphi-neon">delphi-neon</a> library</li>
<li>Rest Server of object using <a href="https://wirl.delphiblocks.dev/">WiRL</a> library</li>
<li>Rest Server of object using <a href="https://github.com/andrea-magni/MARS">MARS Curiosity</a> library</li>
</ol>
<p>From 4.2.2 version a new “Installer” read-to-use is located in the Release area: <a href="https://github.com/EtheaDev/InstantObjects/releases/latest/download/InstantObjects_Setup.exe">Download the Installer</a>.</p>
<p>The Installer automatically detect your Delphi versions, install sources, build and install packages and add source paths.</p>
<p><img src="./Help/Setup.png" alt="Setup" /></p>
<p><strong>Documentation</strong></p>
<p>Follow the complete manual present in this <a href="https://ethea.it/docs/instantobjects/">site</a> and look at the PrimerCross demo to find out how to build applications with an Object Persistence Layer very flexible.</p>
<p><img src="https://raw.githubusercontent.com/wiki/EtheaDev/InstantObjects/PrimerDemo.gif" alt="Primer demo" /></p>
<p><strong>Project Status</strong></p>
<p>The project is still managed by <a href="https://www.ethea.it">Ethea S.r.l.</a>, an italian company that uses InstantObjects for <a href="https://ethea.it/prodotti/instantsolutions/">InstantSolution Framework</a>.</p>

</li>
<li>
<p>InternalRefreshObjects for TInstantNavigationalQuery and
TInstantSQLQuery now uses a BusyObjects list with ownership
reference added to InstantObjects. This ensures that the
InstantObjects in the list are not destroyed prematurely
causing AVs.</p>
</li>
<li>
<p>Object ownership behaviour of TInstantNavigationalResolver
was made consistent with TInstantSQLResolver. Adding or
inserting objects to an InstantSelector now behaves
consistently for Navigational and SQL based brokers.</p>
</li>
<li>
<p>Fix bug in TInstantSQLResolver.ExecuteStatement that only
indicated Info.Success as true if executed query returned
one row.</p>
</li>
<li>
<p>Fix bug in TInstantNavigationalQuery.SetRowNumber so that
loop iteration does not try to go past Dataset.Eof.</p>
</li>
<li>
<p>TInstantQuery.GetConnector now uses the global function
InstantCheckConnector that will try to assign the
DefaultConnector if one has not already been assigned.</p>
</li>
<li>
<p>Embedded and External Parts now behave similarly with respect
to their contained InstantObjects (ie RefCounts and
ownership).</p>
</li>
<li>
<p>Enhanced TInstantCodeAttribute.GetSingularName function.</p>
</li>
<li>
<p>TInstantObject.RestoreState now checks that the object is
in the ObjectStore cache before trying to remove it.</p>
</li>
<li>
<p>Removed TInstantNavigationalQuery.TranslateCommand method
(duplicated code).</p>
</li>
<li>
<p>Now using old DB builder for catalog-less brokers, and new one
for the others.</p>
</li>
<li>
<p>Connection events don't work when database is not connected
through TInstantConnector decendant. They have been removed.</p>
</li>
<li>
<p>Fix for bug # 1285523: Parts of Parts Are Lost when
UpdateExternalPartsMap. When Model include a parts of parts
schema, sometimes when store first level part the second
level parts are lost in DataBase.</p>
</li>
<li>
<p>Allow for catalogs that don't support reading all metadata
(like an XML catalog).</p>
</li>
