public class EventOutMFNodeWrapper
extends EventOutMFNode

Client side implementation of EventOutMFNodeWrapper field. EventOut fields which are used by the vrmlEventChanged broadcast system report only their stored value. EventOut fields produced by Node.getEventOut report only the 'live' value of the field.

Constructor Details

EventOutMFNodeWrapper

public EventOutMFNodeWrapper(int fieldID,
 FieldAndNodeRequestProcessor requestProcessor,
 org.web3d.vrml.scripting.external.neteai.EAIFieldAndNodeFactory factory)

Parameters:

fieldID - The network field ID

requestProcessor - Handler for field services

factory -

EventOutMFNodeWrapper

public EventOutMFNodeWrapper(int fieldID,
 FieldAndNodeRequestProcessor requestProcessor,
 org.web3d.vrml.scripting.external.neteai.EAIFieldAndNodeFactory factory,
 DataInputStream source)
                      throws IOException

Parameters:

fieldID - The network field ID

requestProcessor - Handler for field services

factory -

source - The stream to read field values from

Throws:

IOException

Method Details

equals

public boolean equals(Object other)

Two fields are equal if they point to the same actual node and field

Overrides:

equals in class Object

Parameters:

other - The object to compare against

getFieldID

public int getFieldID()

The underlying field ID

See Also:

• EventWrapper.getFieldID()

getValue

public Node[] getValue()

Description copied from class: EventOutMFNode

Get the value of the array of nodes.

Specified by:

getValue in class EventOutMFNode

Returns:

* @see vrml.eai.field.EventOutMFNode#getValue()

getValue

public void getValue(Node[] nodes)

Description copied from class: EventOutMFNode

Write the value of the array of the nodes to the given array. Individual elements in the array may be null depending on the implementation of the browser and whether it maintains null references.

Specified by:

getValue in class EventOutMFNode

Parameters:

nodes - The node array to be filled in

See Also:

• EventOutMFNode.getValue(vrml.eai.Node[])

get1Value

public Node get1Value(int index)

Description copied from class: EventOutMFNode

Get a particular node value in the given eventOut array.

If the index is out of the bounds of the current array of data values an ArrayIndexOutOfBoundsException will be generated. If the Node value is NULL because the browser implementation keeps null references then this method will return a null pointer without throwing any exception.

Specified by:

get1Value in class EventOutMFNode

Parameters:

index - The position to read the values from

Returns:

* @see vrml.eai.field.EventOutMFNode#get1Value(int)

hashCode

public int hashCode()

In order to make the event queueing system easier, and since an equals method is required by the specification, compute the hashcode based on the field number and underlying node hashcode.

Overrides:

hashCode in class Object

See Also:

• Object.hashCode()

size

public int size()

Description copied from class: EventOutMField

Get the size of the underlying data array.

Specified by:

size in class EventOutMField

Returns:

* @see vrml.eai.field.EventOutMField#size()

addVrmlEventListener

public void addVrmlEventListener(VrmlEventListener l)

Description copied from class: EventOut

Add a listener for changes in this eventOut.

Specified by:

addVrmlEventListener in class EventOut

Parameters:

l - The listener to add

See Also:

• EventOut.addVrmlEventListener(vrml.eai.event.VrmlEventListener)

removeVrmlEventListener

public void removeVrmlEventListener(VrmlEventListener l)

Description copied from class: EventOut

Remove a listener for changes in this eventOut.

Specified by:

removeVrmlEventListener in class EventOut

Parameters:

l - The listener to remove

See Also:

• EventOut.removeVrmlEventListener(vrml.eai.event.VrmlEventListener)

setUserData

public void setUserData(Object data)

Description copied from class: EventOut

Associate user data with this event. Whenever an event is generated on this eventOut. this data will be available with the Event through its getData method.

Specified by:

setUserData in class EventOut

Parameters:

data - The data to associate with this eventOut instance

See Also:

• EventOut.setUserData(java.lang.Object)

getUserData

public Object getUserData()

Description copied from class: EventOut

Get the user data that is associated with this eventOut

Specified by:

getUserData in class EventOut

Returns:

* @see vrml.eai.field.EventOut#getUserData()

loadFieldValue

public void loadFieldValue(DataInputStream input)
                    throws IOException

Throws:

IOException - * @see org.web3d.vrml.scripting.external.neteai.EventWrapper#loadFieldValue(java.io.DataInputStream)
