<p><strong>Context:</strong> The pattern described in this article applies to Dynamics NAV only. For the general definition of the <strong>Singleton</strong> pattern, see for example <a href=https://en.wikipedia.org/wiki/Singleton_pattern>this link</a>.</p>
|
||||
<p><strong>Problem</strong>: As a C/AL developer, you need to coordinate action (through a codeunit) or store information (in a table) that is unique across the system.</p>
|
||||
<p><strong>Forces:</strong></p>
|
||||
<ul>
|
||||
<li><strong>Lost reference to centralizer:</strong> An instance of a relevant object could attempt to centralize control or data in the system. However, once this object is no longer in scope, the reference to it is lost and cannot be retrieved for later coordination</li>
|
||||
<li>**Cannot rebuild the initial state: **A new instance of the same object could be created, however the last known state of the lost instance cannot be known anymore.</li>
|
||||
<li><strong>Cannot rebuild the initial state:</strong> A new instance of the same object could be created, however the last known state of the lost instance cannot be known anymore.</li>
|
||||
</ul>
|
||||
<p><strong>Solution:</strong> create an object which resides in memory in a single copy (instance). Have a way to retrieve this unique object from code. This object can either be a <a href=/nav/w/designpatterns/151.singleton-table><strong>Singleton Table</strong></a>, or a <a href=/nav/w/designpatterns/283.singleton-codeunit><strong>Singleton Codeunit</strong></a>.</p>
|
||||
<p>The implementation varies depending on the technology and language used. In object-oriented (OO) languages like C#, C++ or Java, the <strong>Singleton</strong> uses static classes and class members to instantiate. There is a mechanism to ensure only one instance of the object can exist. This mechanism is many times explicit (like in OO languages) and sometimes implicit as part of the compiler or platform (as it is in NAV).</p>

|
|||
<li><strong>Centralization</strong>: the setup information is stored in a single well-known place and easily retrievable from anywhere in the application code, by invoking a Record.GET. In case of a single-instance codeunit, any reference to it will retrieve the same instance, so the context will be preserved.</li>
|
||||
<li><strong>Persistence</strong>: information remains even after the instance goes out of scope, because it continues to live in memory.</li>
|
||||
</ul>
|
||||
<p>**Limitation: **The generic object-oriented <strong>Singleton</strong> pattern permits instantiation of a limited number n of objects (where usually n=1, but it can have other positive values too). However, in Dynamics NAV, the Singleton patterns are limited: n is always 1.</p>

<p>Cues are the second usual application of the <a href=/nav/w/designpatterns/151.singleton-table><strong>Singleton Table</strong></a> pattern in Dynamics NAV, after <a href=/nav/w/designpatterns/76.setup-table><strong>Setup Tables</strong></a>.</p>
|
||||
<p><strong>Context</strong>: The user gets overview information about the business on the Dynamics NAV Role Center page.</p>
|
||||
<p>Figure 1 - Cue information in Dynamics NAV shows cue information seen by the user on the <strong>Sales Order Processor</strong> role center.</p>
|
||||
<p><a href=Cue-Table-Figure-1.JPG><img src=Cue-Table-Figure-1.JPG alt=" "></a></p>
|
||||
<p>The overview information consists of summed-up numbers, calculated from business data, like for example how many sales orders are still open, how many shipments are ready to go, or partially shipped, how many documents are waiting for approval etc.</p>
|
||||
<p><strong>Problem</strong>: NAV stores data in tables. By definition, a table is a repetitive structure containing multiple lines, each line having a different piece of the information. But sometimes this repetitive information needs to be summed-up or otherwise synthetized, and presented as an overview.</p>
|
||||
<p>**<br>

|
||||
<p><strong>Solution:</strong> Store overview information in a singleton table.</p>

<p>There are two ways of calculating overview information in NAV.</p>

Cues are the second usual application of the Singleton Table pattern in Dynamics NAV, after Setup Tables.
|
||||
Context: The user gets overview information about the business on the Dynamics NAV Role Center page.
|
||||
Figure 1 - Cue information in Dynamics NAV shows cue information seen by the user on the Sales Order Processor role center.
|
||||
The overview information consists of summed-up numbers, calculated from business data, like for example how many sales orders are still open, how many shipments are ready to go, or partially shipped, how many documents are waiting for approval etc.</description></item><item><title>Setup Table</title><link>https://alguidelines.dev/navpatterns/1-patterns/singleton/singleton-table/setup-table/</link><pubDate>Mon, 01 Jan 0001 00:00:00 +0000</pubDate><guid>https://alguidelines.dev/navpatterns/1-patterns/singleton/singleton-table/setup-table/</guid><description>Setup Table By Abhishek Ghosh, at Microsoft Development Center Copenhagen

|

This is the first and most well-known of the two usual applications of the Singleton Table pattern in Dynamics NAV.
|
||||
Problem: the developer needs to store information about the operating setup or environment in the database, in a way that can be persisted across sessions.
|
||||
Solution: The information is stored in a table with one record only. The user is subsequently able to modify, but not add or delete records in the table.</description></item></channel></rss>

<p>This is the first and most well-known of the two usual applications of the <strong>Singleton Table</strong> pattern in Dynamics NAV.</p>
|
||||
<p><strong>Problem:</strong> the developer needs to store information about the operating setup or environment in the database, in a way that can be persisted across sessions.</p>
|
||||
<p><strong>Solution:</strong> The information is stored in a table with one record only. The user is subsequently able to modify, but not add or delete records in the table.</p>
