Class EventInMFVec2f

java.lang.Object
  vrml.eai.field.BaseField
      vrml.eai.field.EventIn
          vrml.eai.field.EventInMFVec2f

public abstract class EventInMFVec2f
extends EventIn

Reference to a MFVec2f event-in slot. Use this class to write values into MFVec2f event-in slots.

The following example demonstrates how to write three texture coordinate values into the "point" field of a TextureCoordinate node:

 vrml.eai.Node textureCoordinate = ...;
 vrml.eai.field.EventInMFVec2f set_point = (vrml.eai.field.EventInMFVec2f)textureCoordinate.getEventIn("set_point");
 float[][] v = new float[3][];
 v[0] = new float[] { 0.0f, 0.0f }; // lower left
 v[1] = new float[] { 1.0f, 0.0f }; // lower right
 v[2] = new float[] { 0.5f, 1.0f }; // top center
 set_point.setValue(v);

Constructor Detail

EventInMFVec2f

protected EventInMFVec2f()

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 MFVec2f event-in slot.

The following example demonstrates how to write three texture coordinate values into the "point" field of a TextureCoordinate node:

 vrml.eai.Node textureCoordinate = ...;
 vrml.eai.field.EventInMFVec2f set_point = (vrml.eai.field.EventInMFVec2f)textureCoordinate.getEventIn("set_point");
 float[][] v = new float[3][];
 v[0] = new float[] { 0.0f, 0.0f }; // lower left
 v[1] = new float[] { 1.0f, 0.0f }; // lower right
 v[2] = new float[] { 0.5f, 1.0f }; // top center
 set_point.setValue(v);
 

Parameters:

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

Throws:

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

set1Value

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

Sets one element of the MFVec2f event-in slot.

The following example demonstrates how to write a texture coordinate value into the first element of the "point" field of a TextureCoordinate node:

 vrml.eai.Node textureCoordinate = ...;
 vrml.eai.field.EventInMFVec2f set_point = (vrml.eai.field.EventInMFVec2f)textureCoordinate.getEventIn("set_point");
 float[] v = new float[] { 0.0f, 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 two float values. The first value is the x component of the vector, and the second value the y component.

Throws:

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