  - setDEF
```
SphereSensor 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 X3DChildNode
    
    Specified by:
    
    setDEF in interface X3DDragSensorNode
    
    Specified by:
    
    setDEF in interface X3DNode
    
    Specified by:
    
    setDEF in interface X3DPointingDeviceSensorNode
    
    Specified by:
    
    setDEF in interface X3DSensorNode
    
    Parameters:
    
    newValue - is new value for the DEF field.
    
    Returns:
    
    SphereSensor - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).
  - setUSE
```
SphereSensor 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.
    
    Specified by:
    
    setUSE in interface X3DChildNode
    
    Specified by:
    
    setUSE in interface X3DDragSensorNode

    Specified by:
    
    setUSE in interface X3DSensorNode
    
    Parameters:
    
    newValue - is new value for the USE field.
    
    Returns:
    
    SphereSensor - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).
  - setCssClass
```
SphereSensor 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
