How to Document Objective-C Blocks With Doxygen?

To document Objective-C blocks with Doxygen, you can include a brief description of the block's purpose and expected behavior. In addition, you should specify the input parameters and return type of the block, as well as any potential side effects or error conditions. It is also helpful to include code examples or usage scenarios to demonstrate how the block should be used in practice. By providing clear and comprehensive documentation for your Objective-C blocks, you can help other developers understand and effectively use your code.

How to document references to related documentation for Objective-C blocks in Doxygen?

To document references to related documentation for Objective-C blocks in Doxygen, you can use the \related command followed by the reference to the related documentation. For example:

1
2
3
4
5
6
7
8

/**
 * This block takes a string as input and returns the length of the string.
 *
 * \related SomeOtherBlock
 */
int (^StringLengthBlock)(NSString *string) = ^(NSString *string) {
    return string.length;
};

In the example above, we have used the \related command to reference another block named SomeOtherBlock that is related to the current block StringLengthBlock. This will create a link to the related documentation in the generated Doxygen output.

How to document performance considerations for Objective-C blocks in Doxygen?

To document performance considerations for Objective-C blocks in Doxygen, you can follow these steps:

1. Use the \performance command in your Doxygen comments to indicate that you are documenting performance considerations for a specific block of code. For example:

1
2
3

/**
 * \performance This block of code has high performance requirements.
 */

1. Provide detailed information about the performance considerations for the Objective-C block in the Doxygen comment. You can include information about the time complexity of the block, any potential bottlenecks, and any optimizations that have been implemented.
2. Use the \note command in your Doxygen comments to provide additional notes about the performance considerations. For example:

1
2
3
4

/**
 * \performance This block of code has high performance requirements.
 * \note Consider using a more efficient algorithm for better performance.
 */

1. Include any relevant code samples or examples in your Doxygen comment to help developers understand the performance considerations for the Objective-C block.

By following these steps, you can effectively document performance considerations for Objective-C blocks in Doxygen and provide valuable information for other developers working with the code.

How to document version information for Objective-C blocks in Doxygen?

To document version information for Objective-C blocks in Doxygen, you can use the following Doxygen commands in your source code comments:

1. Use the \since command to specify the version in which a block was introduced. For example:

1
2
3
4
5
6

/*!
 * \brief Perform a task asynchronously using a block.
 * \param block The block to execute asynchronously.
 * \since 1.0
 */
- (void)performTaskWithBlock:(void (^)(void))block;

1. Use the \remark command to add additional information about the block and its version history. For example:

1
2
3
4
5
6
7

/*!
 * \brief Perform a task asynchronously using a block.
 * \param block The block to execute asynchronously.
 * \since 1.0
 * \remark This method was introduced in version 1.0 of the API.
 */
- (void)performTaskWithBlock:(void (^)(void))block;

1. Use the \version command to specify the version of the block. For example:

1
2
3
4
5
6

/*!
 * \brief Perform a task asynchronously using a block.
 * \param block The block to execute asynchronously.
 * \version 1.0
 */
- (void)performTaskWithBlock:(void (^)(void))block;

By using these Doxygen commands in your Objective-C source code comments, you can effectively document version information for blocks and communicate the history and evolution of your code to other developers.

How to document usage examples for Objective-C blocks in Doxygen?

To document usage examples for Objective-C blocks in Doxygen, you can follow these steps:

1. Use the \code command to indicate that you are providing an example of code.
2. Insert your Objective-C block code within the \code tags.
3. Provide a descriptive comment above the code example to explain what it is demonstrating.
4. Use the \endcode command to close the code example section.

Here is an example of how you can document usage examples for Objective-C blocks in Doxygen:

 1
 2

/**
 * Example of using an Objective-C block as a callback function.
 *
 * The following code demonstrates how to define and use a block as a callback function for a method.
 */
 \code
 // Define a block type for the callback function
 typedef void (^CallbackBlock)(NSInteger);
 
 // Define a method that takes a block as a parameter
 - (void)performOperationWithCallback:(CallbackBlock)callback {
    // Perform some operation
    NSInteger result = 10 * 20;
    
    // Call the callback block with the result
    callback(result);
 }
 
 // Define a block variable and pass it to the method
 CallbackBlock callbackBlock = ^(NSInteger result) {
    NSLog(@"The result of the operation is: %ld", result);
 };
 
 [self performOperationWithCallback:callbackBlock];
 \endcode

By following these steps, you can effectively document usage examples for Objective-C blocks in Doxygen.

How to format code snippets within Objective-C block documentation in Doxygen?

To format code snippets within Objective-C block documentation in Doxygen, you can use the "@code" and "@endcode" commands to enclose the code snippet. Here's an example of how to do this:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14

/**
 * This method performs a calculation on two numbers.
 *
 * @param number1 The first number to use in the calculation.
 * @param number2 The second number to use in the calculation.
 *
 * @return The result of the calculation.
 *
 * @code
 * NSNumber *result = @([number1 integerValue] + [number2 integerValue]);
 * return result;
 * @endcode
 */
- (NSNumber *)performCalculationWithNumber:(NSNumber *)number1 andNumber:(NSNumber *)number2;

In the above example, the code snippet is enclosed within the "@code" and "@endcode" commands, which tells Doxygen to treat the text as code and format it accordingly. When the documentation is generated, the code snippet will be displayed in a fixed-width font and with appropriate syntax highlighting.

How to format Objective-C block documentation for easy readability in Doxygen?

To format Objective-C block documentation for easy readability in Doxygen, you can follow these guidelines:

1. Use the standard Doxygen documentation block format, starting with the /** delimiter and ending with */.
2. Provide a brief description of the block's purpose and usage at the beginning of the block.
3. Use the @param tag to describe each parameter of the block, including the parameter name, data type, and a brief description of its purpose.
4. Use the @return tag to describe the return value of the block, including its data type and a brief description of what it represents.
5. Use the @discussion tag to provide additional context or explanation about the block, such as any potential side effects or important considerations for using it.

By following these guidelines, you can ensure that your Objective-C block documentation is clear, concise, and easy to understand for developers using Doxygen to generate documentation for your code.
