Detailed Description

template<typename Value_type, typename Alloc_type = std::allocator<Value_type>>
class jau::cow_vector< Value_type, Alloc_type >

Implementation of a Copy-On-Write (CoW) using std::vector as the underlying storage, exposing lock-free read operations using SC-DRF atomic synchronization.

This data structure is also supporting Concurrency.

This class shall be compliant with C++ named requirements for Container.

The vector's store is owned using a shared reference to the data structure, allowing its replacement on Copy-On-Write (CoW).

Writing to the store utilizes a mutex lock to avoid data races on the instances' write operations only, leaving read operations lock-free.
Write operations replace the store reference with a new instance using jau::sc_atomic_critical to synchronize with read operations.

Reading from the store is lock-free and accesses the store reference using jau::sc_atomic_critical to synchronizing with write operations.

Immutable storage const_iterators are supported via jau::cow_ro_iterator, which are constructed lock-free.
jau::cow_ro_iterator hold a snapshot retrieved via jau::cow_vector::snapshot() until its destruction.

Mutable storage iterators are supported via jau::cow_rw_iterator, which holds a copy of this CoW storage and locks its write mutex until jau::cow_rw_iterator::write_back() or its destruction.
After completing all mutable operations but before this iterator's destruction, the user might want to write back this iterators' storage to this CoW using jau::cow_rw_iterator::write_back().

Index operation via ::operator[](size_type) or ::at(size_type) are not supported, since they would be only valid if value_type itself is a std::shared_ptr and hence prohibit the destruction of the object if mutating the storage, e.g. via jau::cow_vector::push_back().

Custom mutable write operations are also supported via jau::cow_vector::get_write_mutex(), jau::cow_vector::copy_store() and jau::cow_vector::set_store().
See example in jau::cow_vector::set_store()

Special case facility allowing the user to replace the current store with the given value, potentially acquired via jau::cow_vector::copy_store() and mutated while holding the jau::cow_vector::get_write_mutex() lock.

This is a move operation, i.e. the given new_store_ref is invalid on the caller side after this operation.
User shall pass the store via std::move()

    ...
    {
        std::lock_guard<std::recursive_mutex> lock(list.get_write_mutex());
