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 JavaScript 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:
${IS_ASSIGNMENT_TARGET}   returns 'true' if the created method is an assignment target
${IS_NEW_CALL}   returns 'true' if the created method is under 'new' call
${HAS_EXPECTED_TYPE}   returns 'true' if the created method is in location with expected type
${DEFAULT_RETURN_VALUE}   default value of expected type for the created method ('undefined' if no expected type)
${METHOD_NAME}   name of the created method
All the predefined variables from the File Header template (Includes tab) are also available (e.g. ${USER}, ${DATE}, etc.)
