bsl::function::operator()

Invoke the target with the call arguments, or throw if empty.

Synopsis

Declared in <bslstl_function.h>

using Base::operator();

Description

If this object is empty, throw bsl::bad_function_call; otherwise invoke the target object with the specified args... and return the result (after conversion to RET). Note that, even though it is declared const, this call operator can mutate the target object and is thus considered a manipulator rather than an accessor.
