Interface Layer

All Superinterfaces:
X3DLayerNode, X3DNode, X3DPickableObject
All Known Implementing Classes:
Layer
public interface Layer extends X3DLayerNode
Layer contains a list of children nodes that define the contents of the layer.

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. Layer 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).

    • getObjectType

      String[] getObjectType()
      Provide array of String enumeration results with quoted value(s) ["ALL","NONE","TERRAIN",...] from inputOutput MFString field named objectType.

      Tooltip: The objectType field specifies a set of labels used in the picking process. Each string specified is treated as an independent label that needs to be matched against the same type in one of the pick sensor instances. Example: labeling a PickableGroup with the objectType value "WATER" and then attempting to intersect a pick sensor with objectType value "GROUND" fails since the objectType values do not match. Example: the special value "ALL" means that each node is available for picking regardless of the type specified by the pick sensor. Example: the special value "NONE" effectively disables all picking for this node and is the equivalent of setting the pickable field to false.
      • Hint: authors may define any value for objectType.
      • Hint: MFString arrays can have multiple values, so "separate each individual string" "by using quote marks".
      Specified by:
      getObjectType in interface X3DLayerNode
      Returns:
      value of objectType field

    • setObjectType
