vrml.eai.field
Class EventInSFVec2f

java.lang.Object
  extended by vrml.eai.field.BaseField
      extended by vrml.eai.field.EventIn
          extended by vrml.eai.field.EventInSFVec2f

public abstract class EventInSFVec2f
extends EventIn

Reference to a SFVec2f event-in slot. Use this class to write values into SFVec2f event-in slots.

The following example demonstrates how to translate a texture 0.5 units upwards:

 vrml.eai.Node textureTransform = ...;
 vrml.eai.field.EventInSFVec2f set_translation = (vrml.eai.field.EventInSFVec2f)textureTransform.getEventIn("set_translation");
 float x = 0.0f;
 float y = 0.5f;
 float[] translation = new float[] { x, y };
 set_translation.setValue(translation);

Constructor Detail

EventInSFVec2f

protected EventInSFVec2f()
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 value of a SFVec2f event-in slot.

The following example demonstrates how to translate a texture 0.5 units upwards:

 vrml.eai.Node textureTransform = ...;
 vrml.eai.field.EventInSFVec2f set_translation = (vrml.eai.field.EventInSFVec2f)textureTransform.getEventIn("set_translation");
 float x = 0.0f;
 float y = 0.5f;
 float[] translation = new float[] { x, y };
 set_translation.setValue(translation);
 

Parameters:
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, the second the y component.
Throws:
java.lang.ArrayIndexOutOfBoundsException - when the value array contains less then two values.
