public abstract class BaseCollidableShape
extends BaseCollidableNode

Implementation of the CollidableShape node.

The base class provides most of the basic functionality, including interacting with the ODE portions. However, for returning the scene graph object appropriate for the renderer will require the derived class to take care of it.

The X3D definition of CollidableShape is:

 CollidableShape : X3DNBodyCollidableNode {
   SFNode     [in,out] metadata       NULL     [X3DMetadataObject]
   SFBool     [in,out] enabled     TRUE
   SFVec3f    [in,out] position       0 0 0    (-∞,∞)
   SFRotation [in,out] rotation       0 0 1 0  [0,1]
   SFVec3f    []       bboxCenter     0 0 0    (-∞,∞)
   SFVec3f    []       bboxSize       -1 -1 -1 [0,∞) or -1 -1 -1
   SFBool              bboxDisplay    FALSE
   SFNode     []       shape          NULL     [Shape]
 }

Constructor Details

BaseCollidableShape

public BaseCollidableShape()

Construct a new Collidable shape node object.

BaseCollidableShape

public BaseCollidableShape(VRMLNodeType node)

Construct a new instance of this node based on the details from the given node. If the node is not the same type, an exception will be thrown.

Parameters:

node - The node to copy

Throws:

IllegalArgumentException - The node is not the same type

Method Details

setupFinished

public void setupFinished()

Notification that the construction phase of this node has finished. If the node would like to do any internal processing, such as setting up geometry, then go for it now.

Specified by:

setupFinished in interface VRMLNodeType

Overrides:

setupFinished in class BaseCollidableNode

getFieldIndex

public int getFieldIndex(String fieldName)

Get the index of the given field name. If the name does not exist for this node then return a value of -1.

Parameters:

fieldName - The name of the field we want the index from

Returns:

The index of the field name or -1

getNodeFieldIndices

public int[] getNodeFieldIndices()

Get the list of indices that correspond to fields that contain nodes ie MFNode and SFNode). Used for blind scene graph traversal without needing to spend time querying for all fields etc. If a node does not have any fields that contain nodes, this shall return null. The field list covers all field types, regardless of whether they are readable or not at the VRML-level.

Returns:

The list of field indices that correspond to SF/MFnode fields or null if none

getFieldDeclaration

public VRMLFieldDeclaration getFieldDeclaration(int index)

Get the declaration of the field at the given index. This allows for reverse lookup if needed. If the field does not exist, this will give a value of null.

Parameters:

index - The index of the field to get information

Returns:

A shape of this field's information

getNumFields

public int getNumFields()

Get the number of fields.

Returns:

The number of fields.

getFieldValue

public VRMLFieldData getFieldValue(int index)
                            throws InvalidFieldException

Get the value of a field. If the field is a primitive type, it will return a class representing the value. For arrays or nodes it will return the instance directly.

Specified by:

getFieldValue in interface VRMLNodeType

Overrides:

getFieldValue in class BaseCollidableNode

Parameters:

index - The index of the field to change.

Returns:

The class representing the field value

Throws:

InvalidFieldException - The field index is not known

setValue

public void setValue(int index,
 VRMLNodeType child)
              throws InvalidFieldException,
InvalidFieldValueException

Set the value of the field at the given index as a node. This would be used to set SFNode field types.

Specified by:

setValue in interface VRMLNodeType

Overrides:

setValue in class AbstractNode

Parameters:

index - The index of destination field to set

child - The new value to use for the node

Throws:

InvalidFieldValueException - The node does not match the required type.

InvalidFieldException - The field index is not known

setShape

protected void setShape(VRMLNodeType shape)
                 throws InvalidFieldValueException

Set node content as replacement for the shape field.

Parameters:

shape - The new Shape node to use

Throws:

InvalidFieldValueException - The node does not match the required type.
