public class EventOutSFNodeWrapper
extends EventOutSFNode

Client side implementation of EventOutSFNodeWrapper 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.

Method Summary

Modifier and Type	Method	Description
void	addVrmlEventListener(VrmlEventListener l)	Add a listener for changes in this eventOut.
boolean	equals(Object other)	Two fields are equal if they point to the same actual node and field
int	getFieldID()	The underlying field ID
int	getType()	The type of the underlying field.
Object	getUserData()	Get the user data that is associated with this eventOut
Node	getValue()	Get the node value in the given eventOut.
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.

factory -

EventOutSFNodeWrapper

public EventOutSFNodeWrapper(int fieldID,
 FieldAndNodeRequestProcessor requestProcessor,
 org.web3d.vrml.scripting.external.neteai.EAIFieldAndNodeFactory factory,
 DataInputStream source)
                      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: EventOutSFNode

Get the node value in the given eventOut. If no node reference is set then null is returned to the user.

Specified by:

getValue in class EventOutSFNode

Returns:

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

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()

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:

Throws:

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

getType

int getType()

The type of the underlying field. Method name chosen to coincide with vrml.eai.field.BaseField.

Returns:

the type of the underlying field
