Hi, Coming back to Tutorial08.html, it says :

<<<< It is important to understand that it is possible for a thread to be interrupted at any time by another thread. (...) This can lead to some unstable situations. Consider the following class:

public class threadProblem extends MaxObject { private int[] data = new int[10];

public void bang() { int size = data.length; for (int i=0;i size;i++) { data[i] = i; } }

public void inlet(int i) { data = new int[i]; } }

An int sent in the object's inlet will create a new array of the given length, and a bang will populate the array for numbers. However, consider what would happen if a bang in the main thread (caused by user input, say) was interrupted sometime while executing the bang method and in the scheduler thread a integer was input? If the input is smaller than the previous size of the array, an exception will be thrown shortly after the flow of execution has passed back to the main thread when the for loop exceeds the end of the new array length. (...) >>>>

.

If i understand well, a [delay 0] after any bang sent to the class would solve the problem in this case, am I right ?

In some others situations, where i'll need to pass numbers and lists, will [pipe 0] act the same way - "moving" the data from main to scheduler thread - than [delay 0] ?

i think I understood that if i want to sent critical timing events from java to max, i will need to use outletHigh instead of the outlet methods... and i'm then wondering... on the other way, if a kind of "inletHigh" feature (maybe thought a kind of declareInletHigh(number) method) would have been useful then in the above situation, as an alternative to the delay/pipe stuff ?

Any comment or answer welcome, Thanks, Alexandre
