Method Detail

compare

public int compare(java.lang.Object arg0,
                   java.lang.Object arg1)

Compare two events according to time stamps and values. FIXME Because there is no general compare method for tokens, I implemented the comparison for int and double tokens. A more general compare is required.

Specified by:

compare in interface java.util.Comparator

Parameters:

arg0 - First event.

arg1 - Second event.

Returns:

-1 if event arg0 should be processed before event arg1, 0 if they should be processed at the same time, 1 if arg1 should be processed before arg0.
