CParser Class Reference

class CParser : public CBase

HID parser CParser parses a HID report descriptor. It outputs a CReportRoot containing a tree of CCollection and CField objects representing the descriptor information. A HID device driver can then use this, in conjunction with TReportTranslator and CReportGenerator objects, to facilitate communication with a HID device.

The parsing process conforms to the HID class specification document: "USB Device Class Definition for Human Interface Devices (HID)", Firmware Specification, Version 1.11, USB Implementers' Forum, June 2001.

BitsToRepresentRange(TInt, TInt)

TInt BitsToRepresentRange ( TInt aMin,
TInt aMax
) [private, static]

BitsToRepresentRange() returns the number of bits required to represent all values in a given range. It is used to check that the report field size is appropriate for the given logical minimum and maximum.

If the range is all positive then it is assumed that there is no sign bit, otherwise twos complement format is assumed, as per the HID class specification, v1.11, Section 6.2.2.7.

Warning messages produced during the parse process are added to a list which the driver can retrieve using the Warnings() function. Note that the list will be overwritten by the next ParseL() operation.

Errors and warnings are represented using the format described in "HID Parser Error Codes", Revision 1.2, USB Implementers' Forum, February 2000.

Since
S60 v5.0

Parameters

const TDesC8 & aRawData The report descriptor data to be processed

PopCollection()
