public class DISEntityManager
extends X3DConcreteNode
implements DISEntityManager

DISEntityManager notifies a scene when new DIS ESPDU entities arrive or current entities leave.

X3D node tooltip: [X3DChildNode] DISEntityManager notifies a scene when new DIS ESPDU entities arrive or current entities leave. DISEntityManager may contain any number of DISEntityTypeMapping nodes that provide a best-match X3D model to incoming entity type values. For each new DIS entity, DISEntityManager thus produces a new EspduTransform node that contains a corresponding X3D model.

• Hint: DISEntityManager contains DISEntityTypeMapping nodes.
• Hint: DisEntityManager ESPDU packets use the IEEE Distributed Interactive Simulation (DIS) protocol.
• Warning: 'children' field originally named 'mapping' 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.
