Member Function Documentation

operator uint64_t()

LibXR::TimestampUS::operator uint64_t ( ) const

inline

转换运算符，将时间戳转换为 uint64_t。 Conversion operator to uint64_t.

Definition at line 38 of file libxr_time.hpp.

{ return microsecond_; }

operator-()

TimeDiffUS LibXR::TimestampUS::operator- ( const TimestampUS &  old_microsecond ) const

inline

计算两个时间戳之间的时间差。 Computes the time difference between two timestamps.

Parameters

old_microsecond

旧的时间戳。The older timestamp.

Returns

TimeDiffUS 计算得到的时间差。Computed time difference.

Definition at line 94 of file libxr_time.hpp.

  {
    uint64_t diff;  // NOLINT
 
    if (microsecond_ >= old_microsecond.microsecond_)
    {
      diff = microsecond_ - old_microsecond.microsecond_;
    }
    else
    {
      diff = microsecond_ + (libxr_timebase_max_valid_us - old_microsecond.microsecond_);
    }
 
    ASSERT(diff <= libxr_timebase_max_valid_us);
 
    return TimeDiffUS(diff);
  }

operator=()

TimestampUS & LibXR::TimestampUS::operator= ( const TimestampUS &  other )

inline

赋值运算符重载。 Assignment operator overload.

Parameters

other

另一个 TimestampUS 对象。Another TimestampUS object.

Returns

返回当前对象的引用。Returns a reference to the current object.

Definition at line 118 of file libxr_time.hpp.

  {
    if (this != &other)
    {
      microsecond_ = other.microsecond_;
    }
    return *this;
  }
