Base class for constructing a safe unordered container type that tracks iterators that reference it...
Base class that supports tracking of iterators that reference a sequence.
One of the comparison functors.
The standard allocator, as per [20.4].
_Iterator & base() noexcept
Return the underlying iterator.
Safe class dealing with some allocator dependent operations.
constexpr auto cbegin(const _Container &__cont) noexcept(noexcept(std::begin(__cont))) -> decltype(std::begin(__cont))
Return an iterator pointing to the first element of the const container.
Primary class template hash.
#define __glibcxx_check_erase(_Position)
GNU debug classes for public use.
constexpr auto cend(const _Container &__cont) noexcept(noexcept(std::end(__cont))) -> decltype(std::end(__cont))
Return an iterator pointing to one past the last element of the const container.
_T2 second
The second member.
#define __glibcxx_check_erase_range(_First, _Last)
Class std::unordered_multiset with safety/checking/debug instrumentation.
_Tp * begin(valarray< _Tp > &__va)
Return an iterator pointing to the first element of the valarray.
ISO C++ entities toplevel namespace is std.
_Tp * end(valarray< _Tp > &__va)
Return an iterator pointing to one past the last element of the valarray.
constexpr std::remove_reference< _Tp >::type && move(_Tp &&__t) noexcept
Convert a value to an rvalue.
Struct holding two objects of arbitrary type.
#define __glibcxx_check_insert(_Position)
Class std::unordered_set with safety/checking/debug instrumentation.
Traits class for iterators.
constexpr _Iterator __base(_Iterator __it)
