Detailed Description

回调（ISR）上下文中的互斥锁管理类 (Lock management class for ISR context).

This class attempts to acquire the lock inside an ISR and releases it when the object goes out of scope. 该类尝试在 ISR 中获取锁，并在对象销毁时释放锁。

Constructor & Destructor Documentation

LockGuardInCallback()

LibXR::Mutex::LockGuardInCallback::LockGuardInCallback ( Mutex &  mutex, bool  in_isr  )

inline

构造函数，尝试在 ISR 上下文中加锁 (Constructor attempting to lock the mutex inside ISR context).

Parameters

mutex	需要管理的互斥锁 (Reference to the mutex to manage).
in_isr	指示当前是否处于 ISR 上下文 (Indicates if the function is in ISR context).

Definition at line 132 of file mutex.hpp.

        : mutex_(mutex), success_(mutex_.TryLockInCallback(in_isr)), in_isr_(in_isr)
    {
    }

~LockGuardInCallback()

LibXR::Mutex::LockGuardInCallback::~LockGuardInCallback ( )

inline

析构函数，自动释放锁（如果成功加锁） (Destructor automatically unlocking the mutex if successfully locked).

Definition at line 141 of file mutex.hpp.

    {
      if (success_ == ErrorCode::OK)
      {
        mutex_.UnlockFromCallback(in_isr_);
      }
    }

Member Function Documentation

Locked()

bool LibXR::Mutex::LockGuardInCallback::Locked ( )

inline

检查是否成功加锁 (Check if the mutex was successfully locked).

Returns

如果成功加锁，返回 true，否则返回 false (Returns true if successfully locked, otherwise false).

Definition at line 155 of file mutex.hpp.

{ return success_ == ErrorCode::OK; }
