public class PickableGroupObject
extends X3DConcreteNode
implements PickableGroup
```
X3D node tooltip: (X3D version 3.2 or later) [X3DGroupingNode,X3DPickableObject] PickableGroup is a Grouping node that can contain most nodes. PickableGroup contains children that are marked as having a given classification of picking types, and can also enable or disable picking of the children.
- Hint: insert a Shape node before adding geometry or Appearance.
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.

    Tooltip: Bounding box size is usually omitted, and can easily be calculated automatically by an X3D player at scene-loading time with minimal computational cost. Bounding box size can also be defined as an optional authoring hint that suggests an optimization or constraint. Hint: can be useful for collision computations or inverse-kinematics (IK) engines. Hint: precomputation and inclusion of bounding box information can speed up the initialization of large detailed models, with a corresponding cost of increased file size.

```
public java.lang.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".
    Available enumeration values for string comparison: ALL, NONE, TERRAIN.

  - setUSE
```
public final PickableGroupObject 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 PickableGroupObject setCssClass(SFStringObject newValue)

  - getIS
```
public ISObject getIS()
```
    Provide field named IS for establishing IS/connect field connections between ProtoInterface fields and internal ProtoBody nodes. The IS statement connects node fields defined inside a ProtoBody declaration back to corresponding ProtoInterface fields.
    
    Specified by:
    
    getIS in class X3DConcreteNode
    
    Returns:
    
    current ISObject, if any.

  - setUSE
```
public PickableGroupObject setUSE(PickableGroupObject DEFnode)
```
    Assign a USE reference to another DEF node of same node type, similar to setUSE(String).
    
    Warning: note that 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.
    
    Parameters:
    
    DEFnode - must have a DEF value defined
    
    Returns:
    
    PickableGroupObject - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).
