as_read_only()

template<typename type_t , typename allocator_t = xtd::collections::generic::helpers::allocator<typename std::conditional<std::is_same<bool, type_t>::value, char, type_t>::type>>

read_only_collection xtd::collections::generic::list< type_t, allocator_t >::as_read_only ( ) const

inlinenoexcept

Returns a read-only xtd::collections::object_model::read_only_collection <type_t> wrapper for the current collection.

Returns

An object that acts as a read-only wrapper around the current xtd::collections::generic::list <type_t>.

Remarks

To prevent any modifications to the xtd::collections::generic::list <type_t> object, expose it only through this wrapper. A xtd::collections::object_model::read_only_collection <type_t> object does not expose methods that modify the collection. However, if changes are made to the underlying xtd::collections::generic::list <type_t> object, the read-only collection reflects those changes.

This method is an O(1) operation.
