Annotating Your Code

DocBox reads your CFCs and creates documentation according to your objects, inheritance, implementations, functions, arguments, comments and metadata. We try to follow the JavaDoc style of annotations even though it is not 100% compatible yet.

DocBox Comments

DocBox comments may be placed above any CFC, property, function, or argument which we want to document.

/**
 * This is a Javadoc compliant comment for DocBox
 */

These comments are commonly made up of two sections:

  • The description of what we're commenting on

  • The standalone block tags (marked with the @ symbol) which describe specific meta-data

  • Also all core engine attributes to components, properties, functions and arguments will be documented automatically for you.

For the full JavaDoc spec click here: https://www.oracle.com/technical-resources/articles/java/javadoc-tool.html

DocBox at the CFC Level

/**
* Hero is the main entity we'll be using to create awesome stuff
* 
* @author Captain America
* 
*/
component name="SuperHero" accessors="true" transient{
    // properties and functions
}

This is a simple component declaration where we define the hint for the component and add block tags like @author . All attributes to the component will be documented for you as name-value pairs on the final output.

DocBox at the Property Level

/**
* Hero is the main entity we'll be using to create awesome stuff
* 
* @author Captain America
* 
*/
component name="SuperHero" accessors="true" transient{
    
    /**
     * A collection of aliases this superhero is known as
     */
    property name="alias" type="array";
    
    /**
     * Internal alias name
     * @deprecated true
     */
    property name="_alias" type="array";
}

Properties also have comments and you can add @ blocks as well.

DocBox at the Function Level

/**
 * get Java FileInputStream for resource bundle
 *
 * @rbFilePath path + filename for resource, including locale + .properties
 *
 * @return java.io.FileInputStream
 * @throws ResourceBundle.InvalidBundlePath
 */
public function getResourceFileInputStream( required string rbFilePath ){
}

Functions can have a variety of block tags alongside the main description of the function. Also notice that each argument can also be documented via the @argName block tag.

Argument Annotations

Arguments can also have multiple annotations for documentation or semantic usage purposes.

cBox at the Function Level
/**
 * get Java FileInputStream for resource bundle
 *
 * @rbFilePath path + filename for resource, including locale + .properties
 * @rbFilePath.deprecated true
 *
 * @return java.io.FileInputStream
 * @throws ResourceBundle.InvalidBundlePath
 */
public function getResourceFileInputStream( required string rbFilePath ){
}

This is done by using a . period delimiter and then adding another block name or semantic name to use.

Core Blocks

Here are some of the core blocks that can be used in DocBox:

Tag
Explanation

@author

Provides information about the author, typically the author’s name, e-mail address, website information, and so on.

@version

Indicates the version number.

@since

Used to indicate the version with which this class, field, or method was added.

@return

Provides a description of a method’s return value.

@throws

Indicates exceptions that are thrown by a method or constructor. You can add multiple @throws in a function declaration.

@deprecated

Indicates that the class, field, or method is deprecated and shouldn’t be used.

@{anything}

Anything you like. That's right, DocBox will document any block pairs for you in a simple output manner.

@see

Not implemented yet

Custom DocBox Blocks

Here are some blocks that ONLY DocBox can read:

Tag
Explanation

@doc_abstract

Used on components to demarcate them as abstract components. Please note that you can also use the abstract attribute that ColdFusion 2016+ introduced.

@doc_generic

This is an annotation that can be placed on either a function or argument declaration. This annotation is used to specify what generic type is being used, which is particularly useful when a return or argument type is an array or a struct or any. The value can be a single type or a list.

/**
 * @doc_abstract true
 */
component doc_abstract="true" { ... }
component doc_abstract { ... }


/**
 * Get foo array
 * 
 * @doc_generic com.Foo
 */
private array function getFooArray(){
  return variables.foo;
}

// Inline
private array function getFooArray() doc_generic="com.Foo"{
  return variables.foo;
}

/**
 * Set my struct
 *
 * @myStruct.doc_generic uuid,string
 */
private void function setMyStruct( required struct myStruct ){
  instance.myStruct = arguments.myStruct;
}

// Inline
private void function setMyStruct( 
  required struct myStruct doc_generic="uuid,string" 
){
  instance.myStruct = arguments.myStruct;
}
