示例1: collectTimeStamp
bool VTTParser::collectTimeStamp(VTTScanner& input, double& timeStamp)
{
// Collect a WebVTT timestamp (5.3 WebVTT cue timings and settings parsing.)
// Steps 1 - 4 - Initial checks, let most significant units be minutes.
enum Mode { Minutes, Hours };
Mode mode = Minutes;
// Steps 5 - 7 - Collect a sequence of characters that are 0-9.
// If not 2 characters or value is greater than 59, interpret as hours.
int value1;
unsigned value1Digits = input.scanDigits(value1);
if (!value1Digits)
return false;
if (value1Digits != 2 || value1 > 59)
mode = Hours;
// Steps 8 - 11 - Collect the next sequence of 0-9 after ':' (must be 2 chars).
int value2;
if (!input.scan(':') || input.scanDigits(value2) != 2)
return false;
// Step 12 - Detect whether this timestamp includes hours.
int value3;
if (mode == Hours || input.match(':')) {
if (!input.scan(':') || input.scanDigits(value3) != 2)
return false;
} else {
value3 = value2;
value2 = value1;
value1 = 0;
}
// Steps 13 - 17 - Collect next sequence of 0-9 after '.' (must be 3 chars).
int value4;
if (!input.scan('.') || input.scanDigits(value4) != 3)
return false;
if (value2 > 59 || value3 > 59)
return false;
// Steps 18 - 19 - Calculate result.
timeStamp = (value1 * secondsPerHour) + (value2 * secondsPerMinute) + value3 + (value4 * secondsPerMillisecond);
return true;
