12 package org.simantics.scenegraph.utils.variable;
15 * A container for a single dynamic-enabled boolean variable of a scene graph
16 * node. Dynamic-enabled means a variable that potentially has two values: one
17 * static (~ default) and one dynamic. If the dynamic part has a non-null value
18 * 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.
