public abstract class BaseIndexedGeometryNode
extends BaseComponentGeometryNode

Constructor Details

BaseIndexedGeometryNode

protected BaseIndexedGeometryNode(String name)

Construct a default instance of this class with the bind flag set to false and no time information set (effective value of zero).

Parameters:

name - The name of the type of node

Method Details

copy

protected void copy(VRMLComponentGeometryNodeType node)

Set the fields of the binadble node that has the fields set based on the fields of the passed in node. This directly copies the bind state, so could cause some interesting problems. Not sure what we should do with this currently.

Overrides:

copy in class BaseComponentGeometryNode

Parameters:

node - The bindable node to copy info from

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 BaseComponentGeometryNode

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 BaseComponentGeometryNode

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,
 int[] value,
 int numValid)
              throws InvalidFieldException,
InvalidFieldValueException,
InvalidFieldAccessException

Set the value of the field at the given index as an array of integers. This would be used to set MFInt32 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.

InvalidFieldAccessException - The call is attempting to write to a field that does not permit writing now

setCoordIndex

protected void setCoordIndex(int[] value,
 int numValid)

Set the coordIndex field. Override to provide.renderer-specific behaviour, but remember to also call this implementation too.

Parameters:

value - The list of index values to use

numValid - The number of valid indices in the array

setNormalIndex

protected void setNormalIndex(int[] value,
 int numValid)

Set the normalIndex field. Override to provide.renderer-specific behaviour, but remember to also call this implementation too.

Parameters:

value - The list of index values to use

numValid - The number of valid indices in the array

setColorIndex

protected void setColorIndex(int[] value,
 int numValid)

Set the colorIndex field. Override to provide.renderer-specific behaviour, but remember to also call this implementation too.

Parameters:

value - The list of index values to use

numValid - The number of valid indices in the array

setTexCoordIndex

protected void setTexCoordIndex(int[] value,
 int numValid)

Set the texCoordIndex field. Override to provide.renderer-specific behaviour, but remember to also call this implementation too.

Parameters:

value - The list of index values to use

numValid - The number of valid indices in the array
