Detailed Description

时间基类，用于提供高精度时间戳。 Timebase class for providing high-precision timestamps.

该类提供了微秒和毫秒级的时间戳获取接口，并要求派生类实现具体的时间获取方法。 This class provides interfaces for obtaining timestamps in microseconds and milliseconds, and requires derived classes to implement the actual time retrieval methods.

Constructor & Destructor Documentation

Timebase()

LibXR::Timebase::Timebase ( uint64_t  max_valid_us = UINT64_MAX, uint32_t  max_valid_ms = UINT32_MAX  )

inline

默认构造函数，初始化全局时间基指针。 Default constructor, initializing the global timebase pointer.

该构造函数在实例化对象时，将 timebase 指针指向当前对象， 以便静态方法可以访问具体的时间基实例。 This constructor sets the timebase pointer to the current object when an instance is created, allowing static methods to access the specific timebase instance.

Definition at line 30 of file timebase.hpp.

  {
    libxr_timebase_max_valid_ms = max_valid_ms;
    libxr_timebase_max_valid_us = max_valid_us;
    timebase = this;
  }

Member Function Documentation

_get_microseconds()

virtual TimestampUS LibXR::Timebase::_get_microseconds ( )

pure virtual

纯虚函数，获取当前时间的微秒级时间戳（由派生类实现）。 Pure virtual function for obtaining the current timestamp in microseconds (implemented by derived classes).

该函数需要在派生类中实现，以提供具体的时间获取机制。 This function must be implemented in derived classes to provide the actual time retrieval mechanism.

Returns

返回当前的时间戳（单位：微秒）。 Returns the current timestamp (in microseconds).

Implemented in LibXR::LinuxTimebase, LibXR::STM32Timebase, and LibXR::STM32TimerTimebase.

_get_milliseconds()

virtual TimestampMS LibXR::Timebase::_get_milliseconds ( )

pure virtual

纯虚函数，获取当前时间的毫秒级时间戳（由派生类实现）。 Pure virtual function for obtaining the current timestamp in milliseconds (implemented by derived classes).

该函数需要在派生类中实现，以提供具体的时间获取机制。 This function must be implemented in derived classes to provide the actual time retrieval mechanism.

Returns

返回当前的时间戳（单位：毫秒）。 Returns the current timestamp (in milliseconds).

Implemented in LibXR::LinuxTimebase, LibXR::STM32Timebase, and LibXR::STM32TimerTimebase.

GetMicroseconds()

static TimestampUS LibXR::Timebase::GetMicroseconds ( )

inlinestatic

获取当前时间的微秒级时间戳。 Gets the current timestamp in microseconds.

该函数通过静态方法调用 _get_microseconds()， 从 timebase 实例中获取当前时间。 This function calls _get_microseconds() via a static method to retrieve the current time from the timebase instance.

Returns

返回当前的时间戳（单位：微秒）。 Returns the current timestamp (in microseconds).

Definition at line 49 of file timebase.hpp.

{ return timebase->_get_microseconds(); }

GetMilliseconds()

static TimestampMS LibXR::Timebase::GetMilliseconds ( )

inlinestatic

获取当前时间的毫秒级时间戳。 Gets the current timestamp in milliseconds.

该函数通过静态方法调用 _get_milliseconds()， 从 timebase 实例中获取当前时间。 This function calls _get_milliseconds() via a static method to retrieve the current time from the timebase instance.

Returns

返回当前的时间戳（单位：毫秒）。 Returns the current timestamp (in milliseconds).

Definition at line 63 of file timebase.hpp.

{ return timebase->_get_milliseconds(); }

Field Documentation

timebase

Timebase* LibXR::Timebase::timebase = nullptr

inlinestatic

静态指针，用于存储全局时间基对象。 Static pointer storing the global timebase instance.

该指针指向当前生效的 Timebase 实例，所有静态时间函数都通过该指针访问实际实现。 This pointer refers to the currently active Timebase instance, and all static time functions access the actual implementation through this pointer.
