BloombergLP::bslstl::SharedPtrUtil::staticCast

Load target with a static_cast alias of source.

Synopsis

Declared in <bslstl_sharedptr.h>

template<
    class TARGET,
    class SOURCE>
static
void
staticCast(
    bsl::shared_ptr<TARGET>* target,
    bsl::shared_ptr<SOURCE> const& source);

Description

Load into the specified target an aliased shared pointer sharing ownership of the object managed by the specified source shared pointer and referring to static_cast<TARGET *>(source.get()). If *target is already managing a (possibly shared) object, then release the shared reference to that object, and destroy it using its associated deleter if that shared pointer held the last shared reference to that object. Note that a compiler diagnostic will be emitted indicating an error unless static_cast<TARGET *>(source.get()) is a valid expression.

Parameters

NameDescription
targetdestination shared pointer loaded by the cast
sourcesource shared pointer that supplies ownership
