<p>Runtime views iterate over those entities that are at least in the given storage. During initialization, a runtime view looks at the number of entities available for each component and uses the smallest set in order to get a performance boost when iterating.</p>
|
|
<p><b>Important</b> </p>
|
|
<p>Iterators aren't invalidated if:</p>
|
|
<ul>
|
|
<li>New elements are added to the storage.</li>
|
|
<li>The entity currently pointed is modified (for example, components are added or removed from it).</li>
|
|
<li>The entity currently pointed is destroyed.</li>
|
|
</ul>
|
|
<p>In all other cases, modifying the storage iterated by the view in any way invalidates all the iterators.</p>
