Constructor Details

BaseTextureTransform3D

protected BaseTextureTransform3D()

Construct a new default instance of this class.

BaseTextureTransform3D

protected BaseTextureTransform3D(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

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.

Specified by:

getFieldIndex in interface VRMLNode

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.

Specified by:

getNodeFieldIndices in interface VRMLNode

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.

Specified by:

getFieldDeclaration in interface VRMLNode

Parameters:

index - The index of the field to get information

Returns:

A representation of this field's information

getNumFields

public int getNumFields()

Get the number of fields.

Specified by:

getNumFields in interface VRMLNode

Returns:

The number of fields.

getPrimaryType

public int getPrimaryType()

Get the primary type of this node. Replaces the instanceof mechanism for use in switch statements.

Specified by:

getPrimaryType in interface VRMLNode

Returns:

The primary type

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 AbstractNode

Parameters:

index - The index of the field to change.

Returns:

The class representing the field value

Throws:

InvalidFieldException - The field index is not known

sendRoute

public void sendRoute(double time,
 int srcIndex,
 VRMLNodeType destNode,
 int destIndex)

Send a routed value from this node to the given destination node. The route should use the appropriate setValue() method of the destination node. It should not attempt to cast the node up to a higher level. Routing should also follow the standard rules for the loop breaking and other appropriate rules for the specification.

Specified by:

sendRoute in interface VRMLNodeType

Overrides:

sendRoute in class AbstractNode

Parameters:

time - The time that this route occurred (not necessarily epoch time. Should be treated as a relative value only)

srcIndex - The index of the field in this node that the value should be sent from

destNode - The node reference that we will be sending the value to

destIndex - The index of the field in the destination node that the value should be sent to.

setValue

public void setValue(int index,
 float[] value,
 int numValid)
              throws InvalidFieldException,
InvalidFieldValueException

Set the value of the field at the given index as an array of floats. This would be used to set SFColor and SFVec3f field types.

Specified by:

setValue in interface VRMLNodeType

Overrides:

setValue in class AbstractNode

Parameters:

index - The index of destination field to set

value - The new value to use for the node

numValid - The number of valid values to copy from the array

Throws:

InvalidFieldException - The index does not match a known field

InvalidFieldValueException - The value provided is out of range for the field type.
