Member Functions

Name	Description
`CopyMoveTracker` [constructor]	Constructors
`operator=`	Assignment operators
`copyMoveState`	Return this object's state.
`hasUnknownCopyMoveState`	Return `true` if this object's state includes the `e_UNKNOWN` bit. This attribute can be `true` only if `setCopyMoveState` was called with an enumerator value that includes the `e_UNKNOWN` bit.
`isCopiedConstInto`	Return `true` if this object's state includes the `e_COPIED_CONST_INTO` bits but not `e_UNKNOWN`. This attribute is `true` if this object was copy constructed or copy assigned from a `const` lvalue (or, in C++03, from a prvalue).
`isCopiedInto`	Return `true` if this object's state includes the `e_COPIED_INTO` bit but not `e_UNKNOWN`. This attribute is `true` if either `isCopiedConstInto()` or `isCopiedNonconstInto()` is true.
`isCopiedNonconstInto`	Return `true` if this object's state includes the `e_COPIED_NONCONST_INTO` bits but not `e_UNKNOWN`. This attribute is `true` if this object was copy constructed or copy assigned from a non-`const` lvalue.
`isMovedFrom`	Return `true` if this object's state includes the `e_MOVED_FROM` bit but not `e_UNKNOWN`. This attribute is `true` if this object was the argument of the move constructor or the rhs of the move assignment operator and was not subsequently modified.
`isMovedInto`	Return `true` if this object's state includes the `e_MOVED_INTO` bit but not `e_UNKNOWN`. This attribute is `true` if this object was move constructed or was the lhs the of move assignment operator.
`isOriginal`	Return `true` if this object is not in a copied-into, moved-into, or unknown state. This attribute is `true` if this object was default constructed or reset and not subsequently assigned to.
`resetCopyMoveState`	Set this object to the `e_NOT_COPIED_OR_MOVE` state.
`setCopyMoveState`	Set this object to the specified `state`, which might be the bitwise OR of `e_MOVED_FROM` and one of the other enumerator values. The behavior is undefined unless `CopyMoveState::isValid(state)` is `true`.
`swapCopyMoveStates`	Set the state of both the specified `this` and `b` objects to the bitwise OR of `e_MOVED_INTO` and `e_MOVED_FROM`.

Name	Description
`BloombergLP::bsltf::setCopyMoveState`	Set the object at the specified `tracker` address to the specified `state`. This function is an ADL customization point used by `CopyMoveState::set(obj, state)`. The behavior is undefined unless `CopyMoveState::isValid(state)` is `true`.
`BloombergLP::bsltf::copyMoveState`	Return the state of the specified `tracker`. This function is an ADL customization point used by `CopyMoveState::get(obj)`.
`BloombergLP::bsltf::operator!=`	Return `false`; the copy/move state is not a salient attribute, so all `CopyMoveTracker` objects compare equal. Note that this operator is called implicitly if a client class defines a defaulted comparison operator (C++20), but will not be selected by overload resolution for a derived class having no comparison operator.
`BloombergLP::bsltf::operator==`	Return `true`; the copy/move state is not a salient attribute, so all `CopyMoveTracker` objects compare equal. Note that this operator is called implicitly if a client class defines a defaulted comparison operator (C++20), but will not be selected by overload resolution for a derived class having no comparison operator.
