Class EventInMFVec3f

java.lang.Object
  vrml.eai.field.BaseField
      vrml.eai.field.EventIn
          vrml.eai.field.EventInMFVec3f

public abstract class EventInMFVec3f
extends EventIn

Reference to a MFVec3f event-in slot. Use this class to write values into MFVec3f event-in slots.

The following example demonstrates how to write three position values into the "point" field of a Coordinate node:

 vrml.eai.Node coordinate = ...;
 vrml.eai.field.EventInMFVec3f set_point = (vrml.eai.field.EventInMFVec3f)coordinate.getEventIn("set_point");
 float[][] v = new float[3][];
 v[0] = new float[] { -1.0f, -1.0f, 0.0f }; // lower left
 v[1] = new float[] { 1.0f, -1.0f, 0.0f }; // lower right
 v[2] = new float[] { 0.0f, 1.0f, 0.0f }; // top center
 set_point.setValue(v);

Constructor Detail

EventInMFVec3f

protected EventInMFVec3f()

Default constructor. This method is protected, i.e. you cannot create new instances of this class. The only way to get instances is via the Node.getEventIn(java.lang.String) method.

Method Detail

setValue

public abstract void setValue(float[][] value)
                       throws java.lang.ArrayIndexOutOfBoundsException

Sets the elements of the MFVec3f event-in slot.

The following example demonstrates how to write three position values into the "point" field of a Coordinate node:

 vrml.eai.Node coordinate = ...;
 vrml.eai.field.EventInMFVec3f set_point = (vrml.eai.field.EventInMFVec3f)coordinate.getEventIn("set_point");
 float[][] v = new float[3][];
 v[0] = new float[] { -1.0f, -1.0f, 0.0f }; // lower left
 v[1] = new float[] { 1.0f, -1.0f, 0.0f }; // lower right
 v[2] = new float[] { 0.0f, 1.0f, 0.0f }; // top center
 set_point.setValue(v);
 

Parameters:

value - The new vector values. This is an array of float arrays that contain at least three values. The first value is the x component of the vector, the second value the y component, and the third value the z component.

Throws:

java.lang.ArrayIndexOutOfBoundsException - when one of the arrays in the value parameter contains less than three values.

set1Value

public abstract void set1Value(int index,
                               float[] value)
                        throws java.lang.ArrayIndexOutOfBoundsException

Sets one element of the MFVec3f event-in slot.

The following example demonstrates how to write a new position value into the first element of the "point" field of a Coordinate node:

 vrml.eai.Node coordinate = ...;
 vrml.eai.field.EventInMFVec3f set_point = (vrml.eai.field.EventInMFVec3f)coordinate.getEventIn("set_point");
 float[] v = new float[] { -1.0f, -1.0f, 0.0f };
 set_point.set1Value(0, v);
 

Parameters:

index - The index of the element, starting at 0.

value - The new vector value. This is an array of at least three float values. The first value is the x component of the vector, the second value the y component, and the third value the z component.

Throws:

java.lang.ArrayIndexOutOfBoundsException - when the index is invalid, or the value array contains less then three values.
