Class LoadSensorObject

java.lang.Object
org.web3d.x3d.jsail.X3DConcreteElement
org.web3d.x3d.jsail.X3DConcreteNode
org.web3d.x3d.jsail.Networking.LoadSensorObject
All Implemented Interfaces:
X3DChildNode, X3DNode, X3DSensorNode, LoadSensor, X3DNetworkSensorNode

public class LoadSensorObject
extends X3DConcreteNode
implements LoadSensor
LoadSensor generates events as watchList child nodes are either loaded or fail to load.

X3D 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 is not sensed due to multiple-image ambiguity.
  • Warning: 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.

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.

      public LoadSensorObject setUSE​(LoadSensorObject DEFnode)
      Assign a USE reference to another DEF node of same node type, similar to setUSE(String).

      Warning: note that the setUSE() method on this node resets all other fields to their default values (except for containerField) and also releases all child nodes.

      Warning: no other operations can be performed to modify a USE node other than setting an alternate containerField value.
      Parameters:
      DEFnode - must have a DEF value defined
      Returns:
      LoadSensorObject - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).
