Detailed Description

template<typename Type>
struct cds::opt::value_cleaner< Type >

[type-option] value cleaning

The cleaner is a functor called when an item is removed from a container. Note, the cleaner should not delete (deallocate) the value val passed in. However, if the value_type type is a structure that contains dynamically allocated field(s), the cleaning functor may deallocate it and initialize to default value (usually, nullptr).

The interface for type value_type is:

struct myCleaner {
    void operator ()( value_type& val )
    {
        ...
        // code to cleanup val
    }
}

Predefined option types:

• opt::v::empty_cleaner
• opt::v::destruct_cleaner
• opt::v::auto_cleaner
