Method Summary

Modifier and Type	Method	Description
void	doEvent()	The EventIn*Wrapper classes implement doEvent by posting their stored values to the underlying implementation.
boolean	equals(Object other)	Two eventIn's 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 eventIn
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.
boolean	isConglomerating()	Is the event conglomerating or non-conglomerating.
void	loadFieldValue(DataInputStream input)
void	set1Value(int index, float[] value)	Set a particular vector value in the given eventIn array.

Constructor Details

EventInMFVec2fWrapper

public EventInMFVec2fWrapper(int fieldID,
 FieldAndNodeRequestProcessor requestProcessor,
 NetworkEventQueue eventQueue)

Parameters:

fieldID - The network field ID

requestProcessor - Handler for field services

eventQueue - The queue to send events to

EventInMFVec2fWrapper

public EventInMFVec2fWrapper(int fieldID,
 FieldAndNodeRequestProcessor requestProcessor,
 NetworkEventQueue eventQueue,
 float[][] newValue)

Parameters:

fieldID - The network field ID

requestProcessor - Handler for field services

eventQueue - The queue to send events to

newValue - The value to initialize the field with

Method Details

doEvent

public void doEvent()

The EventIn*Wrapper classes implement doEvent by posting their stored values to the underlying implementation.

Specified by:

doEvent in interface ExternalEvent

See Also:

• ExternalEvent.doEvent()

equals

public boolean equals(Object other)

Two eventIn's 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()

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()

isConglomerating

public boolean isConglomerating()

Description copied from interface: ExternalEvent

Is the event conglomerating or non-conglomerating. Conglomerating events such as the set1Value calls build up in the event buffer.

Specified by:

isConglomerating in interface ExternalEvent

Returns:

whether event is conglomerating or not

See Also:

• ExternalEvent.isConglomerating()

setValue

public void setValue(float[][] value)

Description copied from class: EventInMFVec2f

Set the value of the array of 2D vectors. Input is an array of floats If value[i] does not contain at least two values it will generate an ArrayIndexOutOfBoundsException. If value[i] contains more than two items only the first two values will be used and the rest ignored.

If one or more of the values for value[i] are null then the resulting event that is sent to the VRML scene graph is implementation dependent but no error indicator will be set here.

Specified by:

setValue in class EventInMFVec2f

Parameters:

value - The array of vec2f values where
value[i][0] = X
value[i][1] = Y

See Also:

• EventInMFVec3f.setValue(float[][])

set1Value

public void set1Value(int index,
 float[] value)

Description copied from class: EventInMFVec2f

Set a particular vector value in the given eventIn array. To the VRML world this will generate a full MFVec2f event with the nominated index value changed.

The value array must contain at least two elements. If the array contains more than 2 values only the first 2 values will be used and the rest ignored.

If the index is out of the bounds of the current array of data values or the array of values does not contain at least 2 elements an ArrayIndexOutOfBoundsException will be generated.

Specified by:

set1Value in class EventInMFVec2f

Parameters:

index - The position to set the vector value

value - The array of vector values where
value[0] = X
value[1] = Y

See Also:

• EventInMFVec3f.set1Value(int, float[])

setUserData

public void setUserData(Object data)

Description copied from class: EventIn

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

Specified by:

setUserData in class EventIn

Parameters:

data - The data to associate with this eventIn instance

See Also:

• EventIn.setUserData(java.lang.Object)

getUserData

public Object getUserData()

Description copied from class: EventIn

Get the user data that is associated with this eventIn

Specified by:

getUserData in class EventIn

Returns:

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

loadFieldValue

public void loadFieldValue(DataInputStream input)
                    throws IOException

Throws:

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

writeFieldValue

public void writeFieldValue(DataOutputStream output)
                     throws IOException

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
