Field Details

FIELD_VERTEXCOUNT

protected static final int FIELD_VERTEXCOUNT

Index of the vertexCount field

See Also:

• Constant Field Values

vfVertexCount

protected int[] vfVertexCount

The value of the vertexCount field

numVertexCount

protected int numVertexCount

Number of valid values in the line count field

Constructor Details

BaseLineSet

protected BaseLineSet()

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

BaseLineSet

protected BaseLineSet(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 - Incorrect Node Type

Method Details

isLightingEnabled

public boolean isLightingEnabled()

Specifies whether this node requires lighting. Lines are not lit so always return false.

Specified by:

isLightingEnabled in interface VRMLGeometryNodeType

Overrides:

isLightingEnabled in class BaseComponentGeometryNode

Returns:

false

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

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 representation of this field's information

getNumFields

public int getNumFields()

Get the number of fields.

Returns:

The number of fields.

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

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.

setVertexCount

protected void setVertexCount(int[] counts,
 int numValid)
                       throws InvalidFieldValueException

Set the value of the vertexCount field.

Parameters:

counts - The list of counts provided

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

Throws:

InvalidFieldValueException - One or more values were < 2
