Constructor Detail

GLCapabilities

public GLCapabilities(boolean doubleBuffer,
                      boolean stereoView,
                      boolean rgba,
                      int stencilBits,

                      int accumAlphaSize)

GLCapabilities

public GLCapabilities()

Method Detail

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Description copied from class: java.lang.Object

This method may be called to create a new copy of the Object. The typical behavior is as follows:

• o == o.clone() is false
• o.getClass() == o.clone().getClass() is true
• o.equals(o) is true

However, these are not strict requirements, and may be violated if necessary. Of the three requirements, the last is the most commonly violated, particularly if the subclass does not override Object.equals(Object)>Object.equals(Object) 55 .

If the Object you call clone() on does not implement java.lang.Cloneable (which is a placeholder interface), then a CloneNotSupportedException is thrown. Notice that Object does not implement Cloneable; this method exists as a convenience for subclasses that do.

Object's implementation of clone allocates space for the new Object using the correct class, without calling any constructors, and then fills in all of the new field values with the old field values. Thus, it is a shallow copy. However, subclasses are permitted to make a deep copy.

All array types implement Cloneable, and override this method as follows (it should never fail):

 public Object clone()
 {
   try
     {
       super.clone();
     }
   catch (CloneNotSupportedException e)
     {
       throw new InternalError(e.getMessage());
     }
 }

setNativeVisualID

public void setNativeVisualID(long id)

Set the fetched native VisualID. This is an interface for the Factory and GLContext. Because the GLCapabilities are copied through the handling between the Factory and GLContext, you cannot missuse it .. this is the holder for the native visualID, e.g. Win32's number of the PIXELFORMATDESC, or X11's VisualID

---

getNativeVisualID

Get the fetched native VisualID. This is an interface for the Factory and GLContext. this is the holder for the native visualID, e.g. Win32's number of the PIXELFORMATDESC, or X11's VisualID

---

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

main

public static void main(java.lang.String[] args)
