| TransparencyInterpolator | | public class TransparencyInterpolator extends Interpolator (Code) | | TransparencyInterpolator behavior. This class defines a behavior
that modifies the transparency of its target TransparencyAttributes
object by linearly interpolating between a pair of specified
transparency values (using the value generated by the specified
Alpha object).
There are two forms of constructor to specify the
type of transparency interpolation. The first constructor takes
an Alpha and a TransparencyAttributes object and creates a transparency
interpolator that maps an Alpha value of 1.0 to a transparency
value of 1.0, and an Alpha value of 0.0 and maps it to a
transparency value of 0.0. The second constructor takes an Alpha,
a TransparencyAttributes object, a minimum transparency value and a
maximum transparency value. This constructor provides more
flexibility by specifying how the Alpha values are mapped
to the transparency values - an Alpha of 1.0 maps to the
maximum transparency value and an Alpha of 0.0 maps to the
minimum transparency value.

| Method Summary | |
| public Node | cloneNode(boolean forceDuplicate)
Used to create a new instance of the node. | | void | duplicateAttributes(Node originalNode, boolean forceDuplicate)
Copies all TransparencyInterpolator information from
originalNode into
the current node. | | public float | getMaximumTransparency()
This method retrieves this interpolator's maximumTransparency. | | public float | getMinimumTransparency()
This method retrieves this interpolator's minimumTransparency. | | public TransparencyAttributes | getTarget()
This method retrieves this interpolator's target reference. | | public void | processStimulus(Enumeration criteria)
This method is invoked by the behavior scheduler every frame. | | public void | setMaximumTransparency(float transparency)
This method sets the maximumTransparency for this interpolator. | | public void | setMinimumTransparency(float transparency)
This method sets the minimumTransparency for this interpolator. | | public void | setTarget(TransparencyAttributes target)
This method sets the target TransparencyAttributes object
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. |

| TransparencyInterpolator | | TransparencyInterpolator()(Code) | | |
| TransparencyInterpolator | | public TransparencyInterpolator(Alpha alpha, TransparencyAttributes target)(Code) | | Constructs a trivial transparency interpolator with a specified target,
a minimum transparency of 0.0f and a maximum transparency of 1.0f.
Parameters:
alpha - the alpha object for this interpolator
Parameters:
target - the TransparencyAttributes component object affected by this interpolator |
| TransparencyInterpolator | | public TransparencyInterpolator(Alpha alpha, TransparencyAttributes target, float minimumTransparency, float maximumTransparency)(Code) | | Constructs a new transparency interpolator that varies the target
material's transparency between the two transparency values.
Parameters:
alpha - the alpha object for this Interpolator
Parameters:
target - the TransparencyAttributes component object affected by this interpolator
Parameters:
minimumTransparency - the starting transparency
Parameters:
maximumTransparency - the ending transparency |
| 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 TransparencyInterpolator 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.

| getMinimumTransparency | | public float getMinimumTransparency()(Code) | | This method retrieves this interpolator's minimumTransparency.

| getTarget | | public TransparencyAttributes getTarget()(Code) | | This method retrieves this interpolator's target reference.

| 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
transparency value and updates the specified TransparencyAttributes
object with this new transparency value.
Parameters:
criteria - an enumeration of the criteria that caused thestimulus |
| setMaximumTransparency | | public void setMaximumTransparency(float transparency)(Code) | | This method sets the maximumTransparency for this interpolator.
Parameters:
transparency - the new maximum transparency |
| setMinimumTransparency | | public void setMinimumTransparency(float transparency)(Code) | | This method sets the minimumTransparency for this interpolator.
Parameters:
transparency - the new minimum transparency |
| setTarget | | public void setTarget(TransparencyAttributes target)(Code) | | This method sets the target TransparencyAttributes object
for this interpolator.
Parameters:
target - the target TransparencyAttributes object |
| 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.
