Creates the body of an implemented function when it is generated, for example, using the Code | Implement Methods action.
When editing the template, you can use C++ expressions, comments, and the following predefined variables:
${RETURN_TYPE}   the function's return type.
${DEFAULT_RETURN_VALUE}   the function's default return value.
All the predefined variables from the C File Header template (the Includes tab), such as ${USER} and ${DATE}, are available as well.
