[java-dev] deferring a new operation of buf.Op

Hi there,

I'd like to implement a new operation for buf.Op.
I want this operation deferred like Copyinto or Copyfrom are.

I try this script

	public void fade(final int start_index){
		MaxSystem.deferlow(new Executable() {
			public void execute(){
				float val1=0;
				float val2=0;
				for (int c=start_index; c<(start_index+220);c++)
				{
					val1 = MSPBuffer.peek(bufname, 1, c)*((c-start_index)/220);
					val2 = MSPBuffer.peek(bufname, 2, c)*((c-start_index)/220);
					MSPBuffer.poke(bufname, 1, c, val1 );
					MSPBuffer.poke(bufname, 2, c, val2 );
				}
			}
		}
		);
	}

This script gave me a compilation error I don't understand : 

/Applications/MaxMSP 4.6/Cycling '74/java/classes/buf/Op.java[ 127 ] cannot find symbol
symbol  : method deferlow(<anonymous com.cycling74.max.Executable>)
location: class com.cycling74.max.MaxSystem
                MaxSystem.deferlow(new Executable() {
                         ^
1 error
[ 29 janv. 2008 14:36:20 ]
 compilation of /Applications/MaxMSP 4.6/Cycling '74/java/classes/buf/Op.java failed.

I use the same code as the copyinto or copyfrom method. 
Does any of you have an idea ?
Thanks for your help.

NB: I'd like to defer this one as, I'll call this method when I'll read the same buffer. The aim is to make a fade of 5 ms at a given index.
