Functions
-
template <typename T>bool ExtractUint (const uint8_t * report, size_t report_len, const hid::Attributes & attr, T * value_out)Defined at line 53 of file ../../src/ui/input/lib/hid-parser/report.cc
-
bool ExtractAsUnitType (const uint8_t * report, size_t report_len, const hid::Attributes & attr, double * value_out)Extracts |value_out| from |report| as the closest unit type to |attr.unit|. The unit type
can be gotten from the |GetUnitTypeFromUnit| function. This is the recommended
extraction function for the users of this library.
Defined at line 238 of file ../../src/ui/input/lib/hid-parser/report.cc
-
size_t GetReportSizeFromFirstByte (const DeviceDescriptor & desc, ReportType type, uint8_t byte)Gets the size of the report from the first byte of the report.
Defined at line 10 of file ../../src/ui/input/lib/hid-parser/descriptor.cc
-
bool InsertAsUnitType (uint8_t * report, size_t report_len, const hid::Attributes & attr, double value_in)Inserts |value_in| into |report|. This function assumes that |value_in| is in the
unit type closest to |attr.unit|.
Defined at line 227 of file ../../src/ui/input/lib/hid-parser/report.cc
-
bool ExtractAsUnit (const uint8_t * report, size_t report_len, const hid::Attributes & attr, double * value_out)Extracts |value_out| from |report| and ensures that is in the units
specified by |attr|.
Defined at line 97 of file ../../src/ui/input/lib/hid-parser/report.cc
-
bool InsertAsUnit (uint8_t * report, size_t report_len, const hid::Attributes & attr, double value_in)Inserts |value_in| into |report| after it has been translated into
the logical units described by |attr|.
Defined at line 185 of file ../../src/ui/input/lib/hid-parser/report.cc
-
bool ExtractWithUnit (const uint8_t * report, size_t report_len, const hid::Attributes & attr, const Unit & unit_out, double * value_out)Extracts |value_out| from |report| and converts it into the units
specified by |unit_out|.
Defined at line 137 of file ../../src/ui/input/lib/hid-parser/report.cc
-
bool InsertWithUnit (uint8_t * report, size_t report_len, const hid::Attributes & attr, const Unit & unit_in, double value_in)Given |value_in| with units |unit_in|, it converts it to |attr.unit| and
then inserts it into |report|.
Defined at line 217 of file ../../src/ui/input/lib/hid-parser/report.cc
-
bool ExtractUint (const uint8_t * report, size_t report_len, const hid::Attributes & attr, uint8_t * value_out)Helper functions that extracts the raw byte data from a report. This is only
recommended for users that know what they are doing and are willing to
use raw data or do their own conversion between logical and physical values.
Defined at line 82 of file ../../src/ui/input/lib/hid-parser/report.cc
-
bool ExtractUint (const uint8_t * report, size_t report_len, const hid::Attributes & attr, uint16_t * value_out)Defined at line 87 of file ../../src/ui/input/lib/hid-parser/report.cc
-
bool ExtractUint (const uint8_t * report, size_t report_len, const hid::Attributes & attr, uint32_t * value_out)Defined at line 92 of file ../../src/ui/input/lib/hid-parser/report.cc
-
bool InsertUint (uint8_t * report, size_t report_len, const hid::Attributes & attr, uint32_t value_in)Defined at line 147 of file ../../src/ui/input/lib/hid-parser/report.cc
-
template <typename T>T bit_cast (const uint32_t * data)Type punning beyond the magic 'char' type is no longer tolerated
for example the simpler "return *reinterpret_cast<T*>(data);"
generates a warning even on gcc.
Defined at line 155 of file ../../src/ui/input/lib/hid-parser/item.cc
-
template <typename P, typename U>Usage USAGE (P page, U usage)Helper for creating Usage constants.
Defined at line 266 of file ../../src/ui/input/lib/hid-parser/include/lib/hid-parser/parser.h
-
ParseResult ParseReportDescriptor (const uint8_t * rpt_desc, size_t desc_len, DeviceDescriptor ** dev_desc)Defined at line 812 of file ../../src/ui/input/lib/hid-parser/parser.cc
-
void FreeDeviceDescriptor (DeviceDescriptor * dev_desc)Defined at line 843 of file ../../src/ui/input/lib/hid-parser/parser.cc
