Method Index

o assert(boolean)
Crude assertion checking
o db(int, Object, Object)
o db(int, Object, Object, Object)
o db(int, Object, Object, Object, Object)
o db(int, Object, Object, Object, Object, Object)
o db(int, Object, Object, Object, Object, Object, int)
o db(int, String)
Print msg if verbosity >= level
o db(String)
Print msg unconditionally
o moreVerbose()
o now()
o pl(String)
Print msg unconditionally without the header
o tod(int)
Convert a time-stamp from ms to time of day in the format h:mm:ss.mmm This used to be written more "cleanly", but it turned out to consume a huge fraction of the entire time taken by the program, so it was re-written to avoid allocating and concatenating Strings until the very end.

Too bad Java doesn't have sprintf!
