Description

BadWeakPtr [constructor]

Create a BadWeakPtr object. Note that this function is explicitly user‐declared, to make it simple to declare const objects of this type.

~BadWeakPtr [destructor] [virtual]

Destroy this object.

operator=

what [virtual]

Return a pointer to the string literal "bad_weak_ptr", with a storage duration of the lifetime of the program. Note that the caller should not attempt to free this memory. Note that the bsls_exceptionutil macro BSLS_NOTHROW_SPEC is deliberately not used here, as a number of standard libraries declare what in the base exception class explicitly with the no‐throw specification, even in a build that may not recognize exceptions.
