public class SwitchValueInterpolator extends Interpolator
SwitchValueInterpolator behavior. This class defines a behavior that modifies the selected child of the target switch node by linearly interpolating between a pair of specified child index values (using the value generated by the specified Alpha object).

SwitchValueInterpolator
public SwitchValueInterpolator(Alpha alpha, Switch target)
Constructs a SwitchValueInterpolator behavior that varies its target Switch node's child index between 0 and n-1, where n is the number of children in the target Switch node.- Parameters:
alpha
- the alpha object for this interpolatortarget
- the Switch node affected by this interpolator
-
SwitchValueInterpolator
public SwitchValueInterpolator(Alpha alpha, Switch target, int firstChildIndex, int lastChildIndex)
Constructs a SwitchValueInterpolator behavior that varies its target Switch node's child index between the two values provided.- Parameters:
alpha
- the alpha object for this interpolatortarget
- the Switch node affected by this interpolatorfirstChildIndex
- the index of first child in the Switch node to selectlastChildIndex
- the index of last child in the Switch node to select
-
-
Method Detail
-
setFirstChildIndex
public void setFirstChildIndex(int firstIndex)
This method sets the firstChildIndex for this interpolator.- Parameters:
firstIndex
- the new index for the first child
-
getFirstChildIndex
public int getFirstChildIndex()
This method retrieves this interpolator's firstChildIndex.- Returns:
- the interpolator's firstChildIndex
-
setLastChildIndex
public void setLastChildIndex(int lastIndex)
This method sets the lastChildIndex for this interpolator.- Parameters:
lastIndex
- the new index for the last child
-
getLastChildIndex
public int getLastChildIndex()
This method retrieves this interpolator's lastSwitchIndex.- Returns:
- the interpolator's maximum scale value
-
setTarget
public void setTarget(Switch target)
This method sets the target for this interpolator.- Parameters:
target
- the target Switch node
-
getTarget
public Switch getTarget()
This method retrieves this interpolator's target Switch node reference.- Returns:
- the interpolator's target Switch node
-
processStimulus
public void processStimulus(java.util.Enumeration criteria)
This method is invoked by the behavior scheduler every frame. It maps the alpha value that corresponds to the current time into a child index value and updates the specified Switch node with this new child index value.- Specified by:
processStimulus
in classBehavior
- Parameters:
criteria
- an enumeration of the criteria that triggered this stimulus
-
cloneNode
public Node cloneNode(boolean forceDuplicate)
Used to create a new instance of the node. This routine is called bycloneTree
to duplicate the current node.- Overrides:
cloneNode
in classNode
- Parameters:
forceDuplicate
- when set totrue
, causes theduplicateOnCloneTree
flag to be ignored. Whenfalse
, the value of each node'sduplicateOnCloneTree
variable determines whether NodeComponent data is duplicated or copied.- See Also:
Node.cloneTree()
,Node.cloneNode(boolean)
,Node.duplicateNode(javax.media.j3d.Node, boolean)
,NodeComponent.setDuplicateOnCloneTree(boolean)
-
updateNodeReferences
public void updateNodeReferences(NodeReferenceTable referenceTable)
Callback used to allow a node to check if any nodes referenced by that node have been duplicated via a call tocloneTree
. This method is called bycloneTree
after all nodes in the sub-graph have been duplicated. The cloned Leaf node's method will be called and the Leaf node can then look up any node references by using thegetNewObjectReference
method found in theNodeReferenceTable
object. If a match is found, a reference to the corresponding Node in the newly cloned sub-graph is returned. If no corresponding reference is found, either a DanglingReferenceException is thrown or a reference to the original node is returned depending on the value of theallowDanglingReferences
parameter passed in thecloneTree
call.NOTE: Applications should not call this method directly. It should only be called by the cloneTree method.
- Overrides:
updateNodeReferences
in classBehavior
- Parameters:
referenceTable
- a NodeReferenceTableObject that contains thegetNewObjectReference
method needed to search for new object instances.- See Also:
NodeReferenceTable
,Node.cloneTree()
,DanglingReferenceException
