			<description>&lt;p&gt;New page: When working on &lt;a href=&quot;/wiki/NetBeans&quot; title=&quot;NetBeans&quot;&gt;NetBeans&lt;/a&gt; and when writing &lt;a href=&quot;/wiki/TheAPIBook&quot; title=&quot;TheAPIBook&quot;&gt;TheAPIBook&lt;/a&gt; I invented pattern labeled &lt;a href=&quot;/wiki/Singletonizer&quot; title=&quot;Singletonizer&quot;&gt;Singletonizer&lt;/a&gt;.

&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;When working on [[NetBeans]] and when writing [[TheAPIBook]] I invented pattern labeled [[Singletonizer]]. At that time (before 2008) there wasn't a lot of research on this topic. Now, fifteen years later, there seems to be some academic papers (like [https://i.cs.hku.hk/~bruno/papers/toplas2021.pdf Compositional Programming]) and they call this kind of pattern '''Object Algebras'''.&lt;br /&gt;
&lt;br /&gt;
As far as I can say the ''essential aspect'' of [[ObjectAlgebras]] is to avoid '''new''' - just like in case of [[Singletonizer]] and replace it with methods on the [[Singletonizer]]/Algebra class.&lt;br /&gt;
