public class LoadSensor
extends X3DConcreteNode
implements LoadSensor

LoadSensor generates events as watchList child nodes are either loaded or fail to load.

Warning: this is an abstract interface that cannot be instantiated as a concrete object. Java programmers typically only need to use concrete objects provided by the org.web3d.x3d.jsail classes. LoadSensor node tooltip: [X3DNetworkSensorNode] LoadSensor generates events as watchList child nodes are either loaded or fail to load. Changing watchlist child nodes restarts the LoadSensor.

• Hint: use multiple LoadSensor nodes to track multiple loading nodes individually.
• Hint: Background node is not sensed by LoadSensor due to node typing and multiple-image ambiguity, alternatively utilize TextureBackground node with multiple ImageTexture nodes each referenced inside LoadSensor.
• Warning: children (watchList) child nodes are not rendered, so normally USE copies of other nodes to sense load status.
• Hint: use Inline 'load' field to prompt or defer loading.
• Warning: new X3D node, not supported in VRML97.
• Hint: example scenes and authoring assets at https://www.web3d.org/x3d/content/examples/X3dForWebAuthors/Chapter12EnvironmentSensorSound
• Warning: 'children' field originally named 'watchList' in X3Dv3. https://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#fieldNameChanges

Package hint: This org.web3d.x3d.jsail concrete class is used for implementing a standalone X3D object as a Plain Old Java Object (POJO). If you are writing Java code for use inside an X3D Script node, compile separate code using only the org.web3d.x3d.sai package instead.
