public abstract class SoAction
extends Inventor
```
Abstract base class for all actions. SoAction is the base class for all actions. Classes derived from SoAction define operations to be applied at each node encountered during traversal of a scene graph. The function that gets called to implement the action for a particular node type is determined by a lookup table in the global database.
An action may be applied to a node (SoNode), a path (SoPath) or a list of paths (SoPathList).
Hidden references:
Some actions, e.g. SoSearchAction and SoRayPickAction, create one or more SoPath objects when they are applied to the scene graph. The SoPath object references each node in the path. This reference will prevent the node and its associated memory from being reclaimed for as long as the SoPath object exists. These SoPath objects are stored internally in the action and exist until the action object itself is reclaimed or reset.

```
public void useAlternateRep(boolean enable)
```
    Tell the action to use alternate representations during traversal when available.

  - isUsingAlternateRep
```
public boolean isUsingAlternateRep()
```
    Returns true if current action is using alternate representations. Default is false.
  - resetContinueActionInBranchFlag

```
    Initiates an action on the graph defined by a node.
  - apply
```
public void apply(SoPath path)

  - invalidateState
```
public void invalidateState()
```
    Invalidates the current traversal state in the action, forcing it to be recreated when the action is next applied. This is typically unnecessary in most applications.
  - stopActionInBranch
```
public void stopActionInBranch()
```
    This function stops the action in the current Scene Graph branch. Note: It doesn't mean we kill the action!
    It is mainly used to stop the GetBoundingBox action in the SoBBox node.
  - traverse
```
public void traverse(SoNode node)
```
    (Extender API) Does traversal of a graph rooted by a node.
    Extender API is dedicated to extend the toolkit. This api is available to programmers who wish to extend the toolkit. We strongly suggest to use it only in the cases described in the Toolmaker guide such as creating a new class inherited from SoNode. See Open Inventor Toolmaker.
  - clearApplyResult
```
public void clearApplyResult()
```
    When applied, an action may reference nodes or create objects (e.g. SoPath) that reference nodes. This is especially true for SoSearchAction and SoRayPickAction. These references will prevent the nodes from being destroyed and so may appear to be a "memory leak".
    All references are cleared when the action is destroyed or re-applied. However it may be useful to clear them explicitly to remove references to nodes.
  - getPathListAppliedTo
```
public java.util.Vector<SoPath> getPathListAppliedTo()
```
    (Extender API) Returns the path list the action is being applied to.
    Extender API is dedicated to extend the toolkit. This api is available to programmers who wish to extend the toolkit. We strongly suggest to use it only in the cases described in the Toolmaker guide such as creating a new class inherited from SoNode. See Open Inventor Toolmaker.
    Returns NULL if the action is not being applied to the appropriate class.
    Note A single path list may be split into several, one for each different head node. This method allows subclasses to determine the current path list.
  - preDelayedTraversal
```
public boolean preDelayedTraversal()
```
    (Extender API) Method called by SoMultiPassManager before delayed pass traversals.
    Extender API is dedicated to extend the toolkit. This api is available to programmers who wish to extend the toolkit. We strongly suggest to use it only in the cases described in the Toolmaker guide such as creating a new class inherited from SoNode. See Open Inventor Toolmaker.
    Overriding this method can be useful for actions that want to skip the traversal of all delayed passes. Returning false skips the delayed pass traversals.
    
    Since:
    
    Open Inventor 9.1
  - forwardTraversal
```
public void forwardTraversal(SoNode node)
```
    Traverse a node that is not part of the current scenegraph. Like an SoNodeKit, the contents of the specified sub-scenegraph won't be visible as an SoPath. Using the SoPath.full field allows access to the whole path. This method can be used to delegate an action to an internal/private scene graph. So a node can have an internal scene graph without actually being a "group" node. This is a convenient way to implement "composite" nodes that create their behavior using other Open Inventor nodes.
    The node parameter can be of any type. Sensors may still be attached directly to nodes and fields in the internal scene graph.
    This method must not be called from a node derived from SoGroup or SoBaseKit. This method should not be called on nodes that are part of the public/visible scene graph.
  - isBeingApplied
```
public boolean isBeingApplied()
```
    (Extender API) Returns true if this action is currently being applied.
    Extender API is dedicated to extend the toolkit. This api is available to programmers who wish to extend the toolkit. We strongly suggest to use it only in the cases described in the Toolmaker guide such as creating a new class inherited from SoNode. See Open Inventor Toolmaker.
  - forwardTraversal
```
public void forwardTraversal(SoPath path)
```
    Traverse a path that is not part of the current scenegraph. Similar to forwardTraversal(SoNode*) but for paths.
  - nullAction
```
public static void nullAction(SoAction name_7964,
                              SoNode name_7965)
```
    (Extender API) Null action method that can be stored in lookup table when desired.
    Extender API is dedicated to extend the toolkit. This api is available to programmers who wish to extend the toolkit. We strongly suggest to use it only in the cases described in the Toolmaker guide such as creating a new class inherited from SoNode. See Open Inventor Toolmaker.
  - setSceneManager
```
public void setSceneManager(SoSceneManager mgr)
```
    Set the scene manager associated with this action (if any ). When appropriate, this allows the action to query information like the OpenGL rendering context. The SoSCeneManager class calls this method automatically for the actions that it creates (SoHandleEventAction, SoRayPickAction, etc).
  - postDelayedTraversal
```
public void postDelayedTraversal()
```
    (Extender API) Method called by SoMultiPassManager after delayed pass traversals.
    Extender API is dedicated to extend the toolkit. This api is available to programmers who wish to extend the toolkit. We strongly suggest to use it only in the cases described in the Toolmaker guide such as creating a new class inherited from SoNode. See Open Inventor Toolmaker.
    Overriding this method can be useful for actions that want to apply some post processing after all delayed pass traversals.
