All Slice compilers support a metadata directive that allows you to deprecate a Slice definition. For example:

{zcode:slice}
interface Example {
["deprecated:someOperation() has been deprecated, use alternativeOperation() instead."]
void someOperation();
void alternativeOperation();
};
{zcode} |
The ["deprecated"]
metadata directive causes the compiler to emit code that generates a warning if you compile application code that uses a deprecated feature. This is useful if you want to remove a feature from a Slice definition but do not want to cause a hard error.
The message that follows the colon is optional; if you omit the message and use ["deprecated"]
, the Slice compilers insert a default message into the generated code.
You can apply the ["deprecated"]
metadata directive to Slice constructs other than operations (for example, a structure or sequence definition).
