Understanding EAGLView

I am going through the EAGLView files from the apple iphone sample code and I am trying to understand how the EAGLViewDelegate protocol works.

Question:

How is this function called didResizeEAGLSurfaceForView

? I don't see an implementation?

EAGLView.h

@protocol EAGLViewDelegate <NSObject>
- (void) didResizeEAGLSurfaceForView:(EAGLView*)view; 
   //Called whenever the EAGL surface has been resized
@end

@interface EAGLView : UIView
{
  @private
    id<EAGLViewDelegate>    _delegate;
}


@property(assign) id<EAGLViewDelegate> delegate;

EAGLView.m

@implementation EAGLView

@synthesize 
    delegate      = _delegate, 

//......
@end

I am assuming you are referring to the CrashLanding, GLGravity, or GLPaint samples, as these are the only samples I can find in this protocol. DidResizeEAGLSurfaceForView: Called in the MyEAGLView -_createSurface method. However, this method is not implemented anywhere because the delegate is not configured for MyEAGLView in any of these samples.



So no, I don't think you are missing anything. It looks like rudimentary code.
