assertNoAdditionalChildren¶

Overview¶

A utility function that enforces that no additional Children are added to a Node.

In particular, useful for making sure that Nodes are not decorated with other content which can be problematic for dynamic layout. See https://github.com/phetsims/sun/issues/860.

Usage:

const myNode = new Node(); myNode.children = [ new Node(), new Node() ]; // fill in with your own content assertNoAdditionalChildren( myNode ); // prevent new children

Note that removals need to be allowed for disposal.
