public class EventOutMFRotationWrapper
extends EventOutMFRotation

Client side implementation of EventOutMFRotationWrapper 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 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 float[][] getValue()

Description copied from class: EventOutMFRotation

Get the value of the array of rotations. Output is an array of floats values in order required to specify an SFRotation.

Specified by:

getValue in class EventOutMFRotation

Returns:

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

getValue

public void getValue(float[][] vec)

Description copied from class: EventOutMFRotation

Write the value of the event out to the given array.

Specified by:

getValue in class EventOutMFRotation

Parameters:

vec - The array to be filled in where
value[i][0] = X component [0-1]
value[i][1] = Y component [0-1]
value[i][2] = Z component [0-1]
value[i][3] = Angle of rotation [-PI - PI] (nominally).

See Also:

• EventOutMFRotation.getValue(float[][])

getValue

public void getValue(float[] vec)

Description copied from class: EventOutMFRotation

Get the values of the event out flattened into a single 1D array. The array must be at least 4 times the size of the array.

Specified by:

getValue in class EventOutMFRotation

Parameters:

vec - The array to be filled in where the value[i + 0] = X component [0-1]
value[i + 1] = Y component [0-1]
value[i + 2] = Z component [0-1]
value[i + 3] = Angle of rotation [-PI - PI] (nominally).

See Also:

• EventOutMFRotation.getValue(float[])

get1Value

public float[] get1Value(int index)

Description copied from class: EventOutMFRotation

Get a particular rotation 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.

Specified by:

get1Value in class EventOutMFRotation

Parameters:

index - The position to get the rotation value

Returns:

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

get1Value

public void get1Value(int index,
 float[] vec)

Description copied from class: EventOutMFRotation

Get the value of a particular rotation value in the event out array.

Specified by:

get1Value in class EventOutMFRotation

Parameters:

index - The position to get the vector value from.

vec - The array to place the value in where. vec[0] = X component [0-1]
vec[1] = Y component [0-1]
vec[2] = Z component [0-1]
vec[3] = Angle of rotation [-PI - PI] (nominally).

See Also:

• EventOutMFRotation.get1Value(int, float[])

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:
