This is a built-in template used for filling the body of a method when it is generated, e.g. when using the Create method from usage intention action. The template is editable. Along with Java expressions and comments, you can also use predefined variables that will be then expanded into the corresponding values.

Predefined variables will take the following values:
${RETURN_TYPE} |  | return type of a created method
${DEFAULT_RETURN_VALUE} |  | value returned by the method by default
${METHOD_NAME} |  | name of the created method
${CLASS_NAME} |  | qualified name of the class where method is created
${SIMPLE_CLASS_NAME} |  | non-qualified name of the class where method is implemented
All the predefined variables from the File Header template (Includes tab) are also available (e.g. ${USER}, ${DATE}, etc.)
