Class specify_nothing

boost::contract::specify_nothing — Used to prevent setting other contract conditions after exception guarantees.


// In header: <boost/contract/core/specify.hpp>

class specify_nothing {
  // construct/copy/destruct


This class has no member function so it is used to prevent specifying additional functors to check any other contract. This object is internally constructed by the library when users specify contracts calling boost::contract::function and similar functions (that is why this class does not have a public constructor).

See Also:


specify_nothing public construct/copy/destruct

  1. ~specify_nothing();
    Destruct this object.

    Throws: This is declared noexcept(false) since C++11 to allow users to program failure handlers that throw exceptions on contract assertion failures (not the default, see Throw on Failure).
