// This is a "wrapper" class for the SearchableText protocol--
// it doesn't do any searching, but forwards the methods of the
// protocol to the textObj. Normally, such wrappers aren't
// needed. However, to order to time the method calls for this
// example application, rather than instrumenting the MiscFindPanel
// class code, or the code of MiscSearchText, this wrapper class
// was created.
// It is set to be the first conformer in the SBApp class by
// the MiscFindPanelClass category to Application. See the
// documentation for more information on this.
// The "index fields" are not currently used. I was going to try
// and generate some sort of performance index, but decided not
// to. The fields are still in the .nib file too, just hidden.
// The instance variables wallcallms and proccallms are simple
// estimates of the amount of time needed for the timing function
// calls. This calibration occurs when the Timer class is
// instantiated, in -init.
// Any timing results less than 100 ms should be taken with a grain
// of salt. Function call times and the resolution that can be
// achieved varies with the version of NEXTSTEP being used and the
// type of processor. If you are getting times near, or below,
// that you need to increase the amount of text being searched.
// At minimum for example, you should be searching 500K of text on
// a NeXT '040 cube running NS 3.1 if you want to do any half-
// serious benchmarking. Be sure to take into consideration
// memory swapping. And finally, remember that the code of this
// class isn't intended to be very acurate, just give a general
// idea for fun and curiosity.
