| SwitchValueInterpolator | | public class SwitchValueInterpolator extends Interpolator (Code) | | 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).
|
| Constructor Summary | |
| | 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. | | 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. |
| Method Summary | |
| public Node | cloneNode(boolean forceDuplicate)
Used to create a new instance of the node. | | void | duplicateAttributes(Node originalNode, boolean forceDuplicate)
Copies all SwitchValueInterpolator information from
originalNode into
the current node. | | public int | getFirstChildIndex()
This method retrieves this interpolator's firstChildIndex. | | public int | getLastChildIndex()
This method retrieves this interpolator's lastSwitchIndex. | | public Switch | getTarget()
This method retrieves this interpolator's target Switch node
reference. | | public void | processStimulus(Enumeration criteria)
This method is invoked by the behavior scheduler every frame. | | public void | setFirstChildIndex(int firstIndex)
This method sets the firstChildIndex for this interpolator. | | public void | setLastChildIndex(int lastIndex)
This method sets the lastChildIndex for this interpolator. | | public void | setTarget(Switch target)
This method sets the target for this interpolator. | | 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 to cloneTree.
This method is called by cloneTree after all nodes in
the sub-graph have been duplicated. |
| childCount | | int childCount(Code) | | |
| firstSwitchIndex | | int firstSwitchIndex(Code) | | |
| lastSwitchIndex | | int lastSwitchIndex(Code) | | |
| SwitchValueInterpolator | | SwitchValueInterpolator()(Code) | | |
| SwitchValueInterpolator | | public SwitchValueInterpolator(Alpha alpha, Switch target)(Code) | | 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 interpolator
Parameters:
target - the Switch node affected by this interpolator |
| SwitchValueInterpolator | | public SwitchValueInterpolator(Alpha alpha, Switch target, int firstChildIndex, int lastChildIndex)(Code) | | 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 interpolator
Parameters:
target - the Switch node affected by this interpolator
Parameters:
firstChildIndex - the index of first child in the Switch node toselect
Parameters:
lastChildIndex - the index of last child in the Switch node toselect |
| cloneNode | | public Node cloneNode(boolean forceDuplicate)(Code) | | Used to create a new instance of the node. This routine is called
by cloneTree to duplicate the current node.
Parameters:
forceDuplicate - when set to true, causes theduplicateOnCloneTree flag to be ignored. Whenfalse, the value of each node'sduplicateOnCloneTree variable determines whetherNodeComponent data is duplicated or copied.

| duplicateAttributes | | void duplicateAttributes(Node originalNode, boolean forceDuplicate)(Code) | | Copies all SwitchValueInterpolator information from
originalNode into
the current node. This method is called from the
cloneNode method which is, in turn, called by the
cloneTree method.
Parameters:
originalNode - the original node to duplicate.
Parameters:
forceDuplicate - when set to true, causes theduplicateOnCloneTree flag to be ignored. Whenfalse, the value of each node'sduplicateOnCloneTree variable determines whetherNodeComponent data is duplicated or copied.
exception:
RestrictedAccessException - if this object is part of a liveor compiled scenegraph.

| getFirstChildIndex | | public int getFirstChildIndex()(Code) | | This method retrieves this interpolator's firstChildIndex.
the interpolator's firstChildIndex |
| getLastChildIndex | | public int getLastChildIndex()(Code) | | This method retrieves this interpolator's lastSwitchIndex.
the interpolator's maximum scale value |
| getTarget | | public Switch getTarget()(Code) | | This method retrieves this interpolator's target Switch node
reference.
the interpolator's target Switch node |
| processStimulus | | public void processStimulus(Enumeration criteria)(Code) | | 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.
Parameters:
criteria - an enumeration of the criteria that triggeredthis stimulus |
| setFirstChildIndex | | public void setFirstChildIndex(int firstIndex)(Code) | | This method sets the firstChildIndex for this interpolator.
Parameters:
firstIndex - the new index for the first child |
| setLastChildIndex | | public void setLastChildIndex(int lastIndex)(Code) | | This method sets the lastChildIndex for this interpolator.
Parameters:
lastIndex - the new index for the last child |
| setTarget | | public void setTarget(Switch target)(Code) | | This method sets the target for this interpolator.
Parameters:
target - the target Switch node |
| updateNodeReferences | | public void updateNodeReferences(NodeReferenceTable referenceTable)(Code) | | Callback used to allow a node to check if any nodes referenced
by that node have been duplicated via a call to cloneTree.
This method is called by cloneTree 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 the getNewObjectReference method found in the
NodeReferenceTable 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 the
allowDanglingReferences parameter passed in the
cloneTree call.
NOTE: Applications should not call this method directly.
It should only be called by the cloneTree method.
Parameters:
referenceTable - a NodeReferenceTableObject that contains thegetNewObjectReference method needed to search fornew object instances.
