Constructor Details

BaseVolumePickSensor

public BaseVolumePickSensor()

Construct a new time sensor object

BaseVolumePickSensor

public BaseVolumePickSensor(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

getPickingType

public int getPickingType()

Get the picking type that this class represents. A shortcut way of quickly determining the picking strategy to be used by the internal implementation to avoid unnecessary calculations.

Returns:

One of the *_PICK constants

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.
