SpotLightObject (X3DJSAIL, X3D Java Scene Access Interface Library)

java.lang.Object
- org.web3d.x3d.jsail.X3DConcreteElement
- - org.web3d.x3d.jsail.X3DConcreteNode
  - - org.web3d.x3d.jsail.Lighting.SpotLightObject

All Implemented Interfaces:

X3DChildNode, X3DNode, SpotLight, X3DLightNode
```
public class SpotLightObject
extends X3DConcreteNode
implements SpotLight
```
Linear attenuation may occur at level 2, full support at level 3.

X3D node tooltip: [X3DLightNode] SpotLight is a light source that illuminates geometry within a conical beam. Lighting illuminates all geometry except lines and points. By default, light scope only illuminates peer geometry and children nodes within the scene graph hierarchy. Lights have no visible shape themselves and lighting effects continue through any intermediate geometry.
- Hint: the bound NavigationInfo controls whether headlight is enabled on/off.
Note that SFColorObject provides a variety of color constants.

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.

    Parameters:
    
    newValue - is new value for the radius field.
    
    Returns:
    
    SpotLightObject - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).
  - setDEF
```
public final SpotLightObject setDEF(java.lang.String newValue)
```
    Assign String value to inputOutput SFString field named DEF.
    
    Tooltip: DEF defines a unique ID name for this node, referenceable by other nodes. Hint: descriptive DEF names improve clarity and help document a model. Hint: well-defined names can simplify design and debugging through improved author understanding. Hint: X3D Scene Authoring Hints, Naming Conventions http://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#NamingConventions
    
    Note that setting the DEF value clears the USE value.

    Specified by:
    
    setDEF in interface X3DNode
    
    Specified by:
    
    setDEF in interface SpotLight
    
    Specified by:
    
    setDEF in interface X3DLightNode
    
    Specified by:
    
    setDEF in class X3DConcreteNode
    
    Parameters:
    
    newValue - is new value for the DEF field.
    
    Returns:
    
    SpotLightObject - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).
  - setDEF
```
public SpotLightObject setDEF(SFStringObject newValue)
```
    Assign typed object value to SFString DEF field, similar to setDEF(String).
    
    Parameters:
    
    newValue - is new value for the DEF field.
    
    Returns:
    
    SpotLightObject - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).
  - setUSE
```
public final SpotLightObject setUSE(java.lang.String newValue)
```
    Assign String value to inputOutput SFString field named USE.
    
    Tooltip: USE means reuse an already DEF-ed node ID, excluding all child nodes and all other attributes (except for containerField, which can have a different value). Hint: USE references to previously defined DEF geometry (instead of duplicating nodes) can improve performance. Warning: do NOT include any child nodes, a DEF attribute, or any other attribute values (except for containerField) when defining a USE attribute. Warning: each USE value must match a corresponding DEF value that is defined earlier in the scene.
    
    Note: each USE node is still an independent object, with the USE value matching the DEF value in the preceding object.
    
    Warning: invoking 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.

  - setCssClass
```
public final SpotLightObject setCssClass(java.lang.String newValue)
```
    Assign String value to inputOutput SFString field named class.
    
    Tooltip: The class attribute is a space-separated list of classes, reserved for use by CSS cascading stylesheets. Warning: currently the class attribute is only supported in XML encoding of X3D scenes. Hint: W3C Cascading Style Sheets https://www.w3.org/Style/CSS
