Interface Layer

All Superinterfaces:
X3DLayerNode, X3DNode
All Known Implementing Classes:
LayerObject

public interface Layer
extends X3DLayerNode
Layer contains a list of children nodes that define the contents of the layer.

X3D node tooltip: (X3D version 3.2 or later) [X3DLayerNode] Layer contains a list of children nodes that define the contents of the layer.
  • Hint: no transformations are possible above each LayerSet/Layer combination in the scene graph hierarchy.
  • Hint: each Layer node contains its own binding stacks and thus has its own viewpoints and navigation.

Package hint: This interface is defined by the X3D Java Language Binding Specification for the Scene Authoring Interface (SAI).

    • getChildren

      X3DNode[] getChildren()
      Provide array of X3DNode results (using an array consisting of properly typed nodes or ProtoInstanceObjects) from inputOutput MFNode field children.

      • Hint: inputOnly MFNode removeChildren field can remove nodes from the children list, unrecognized input nodes (i.e. nonmatching DEF, USE values) are ignored.

      Parameters:
      newValue - is new value for the children field.
      Returns:
      Layer - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).
    • addChildren

      void addChildren​(X3DNode[] newValue)
      Add array of children nodes to array of existing nodes (if any).

      Note: according to X3D Unified Object Model (X3DUOM), acceptable node types are limited to X3DChildNode.
