3️⃣ Static Class Data
- Use the 'static' keyword before the variable type.
- Declare variables at the class level, outside any methods.
- Ensure proper data type declaration for each static variable.
- Avoid initializing them at this stage.
- Use the scope resolution operator (::) to specify the class.
- Define the initialization outside the class after declaration.
- Provide an initial value for each static member variable.
- Ensure this initialization occurs in a source file, not header.
- Use the class name followed by the scope resolution operator.
- Call static members directly without creating an instance.
- Use this format in both member functions and global functions.
- Ensure visibility of the static member (public or protected).
- Recognize that static data is shared among all class instances.
- Be aware of potential data conflicts if instances modify the data.
- Consider using static data for shared constants or configurations.
- Evaluate the need for instance-specific data vs. static data.
- Use mutexes or locks to protect static data access.
- Consider atomic operations for simple data types.
- Be aware of potential race conditions during concurrent access.
- Document threading considerations for maintainability.
- Include comments explaining the purpose and usage.
- Describe any constraints or expected behavior.
- Clarify ownership and lifecycle of the static data.
- Ensure documentation is accessible to other developers.
- Define static functions when they do not require instance data.
- Use static functions for utility operations related to the class.
- Ensure these functions can be called without class instances.
- Document their purpose and any parameters clearly.
