Constructor Details

BaseGeoSRFSet

public BaseGeoSRFSet()

Construct a default instance of this node. The defaults are set by the X3D specification.

BaseGeoSRFSet

public BaseGeoSRFSet(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

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.

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

setValue

public void setValue(int index,
 int value)
              throws InvalidFieldException,
InvalidFieldValueException

Set the value of the field at the given index as an integer. This would be used to set SFInt32 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

Throws:

InvalidFieldException - The index is not a valid field

InvalidFieldValueException - The field value is not legal for the field specified.

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 strings. This would be used to set the 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 field index is not know

InvalidFieldValueException - The value provided is not in range or not appropriate for this field

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