weak_ptr [constructor] | Constructors |
~weak_ptr [destructor] | Destroy this weak pointer object. If this weak pointer manages a (possibly shared) object, release the weak reference to that object. |
operator= | Assignment operators |
acquireSharedPtr | Return a shared pointer to the object referred to by this weak pointer and managing the same object as that managed by this weak pointer (if any) if false == expired(), and a shared pointer in the empty state otherwise. Note that the behavior of this method is the same as that of lock. |
expired | Return true if this weak pointer is in the empty state or the object that it originally referenced has been destroyed, and false otherwise. |
lock | Return a shared pointer to the object referred to by this weak pointer if false == expired(), and a shared pointer in the empty state otherwise. |
numReferences | Return a "snapshot" of the current number of shared pointers that share ownership of the object referred to by this weak pointer, or 0 if this weak pointer is in the empty state. Note that the behavior of this method is the same as that of use_count, and the result may be unreliable in multi-threaded code for the same reasons. |
owner_before | owner_before overloads |
owner_equal | owner_equal overloads |
owner_hash | Return an unspecified value such that, for any object x where owner_equal(x) is true, owner_hash() == x.owner_hash() is true. Note that this is based on the hash of the address of the BloombergLP::bslma::SharedPtrRep object used by this object. Note also that for two empty smart pointers x and y, x.owner_hash() == y.owner_hash() is true. |
rep | Return the address providing modifiable access to the BloombergLP::bslma::SharedPtrRep object held by this weak pointer, or 0 if this weak pointer is in the empty state. |
reset | Reset this weak pointer to the empty state. If this weak pointer manages a (possibly shared) object, then decrement the number of weak references to that object. |
swap | Efficiently exchange the states of this weak pointer and the specified other weak pointer such that each will refer to the object (if any) and representation (if any) formerly referred to and managed by the other. |
use_count | Return a "snapshot" of the current number of shared pointers that share ownership of the object referred to by this weak pointer, or 0 if this weak pointer is in the empty state. Note that any result other than 0 may be unreliable in a multi-threaded program, where another pointer sharing ownership in a different thread may be copied or destroyed, or another weak pointer may be locked in the case that 1 is returned (that would otherwise indicate unique ownership). |
operator BloombergLP::bslmf::NestedTraitDeclaration<weak_ptr<ELEMENT_TYPE>, is_nothrow_move_constructible> | Nested trait declaration for is_nothrow_move_constructible. |
