12 package org.simantics.scenegraph.utils.variable;
15 * A container for a single dynamic part of a dynamic-enabled variable of a
16 * scene graph node. Dynamic-enabled means a variable that potentially has two
17 * values: one static (~ default) and one dynamic. If the dynamic part has a
18 * non-null value it should always be used instead of the static value. Use
19 * {@link #getActiveValue()} to get the current variable value to follow this
20 * policy in your client code.
23 * Variables generally determine the way a node gets rendered.
