THidFieldSearch Class Reference

class THidFieldSearch

Hid field search THidFieldSearch provides a mechanism for traversing a parsed report descriptor tree (a CReportRoot object). It is intended for a device driver to use when it is looking to see if it is compatible with a newly connected device, i.e. provides the appropriate types of report. The driver must provide an object of a class that implements the MHidFieldFinder interface.
