Class OrderedRegistry<T>

Represents a thread-safe registry of T which is ordered by item's Order property. This class is efficient for concurrent read access and is not designed for cases when frequent modifications happen. It is ideal for lookup of named instances that have much longer time span than components that look them up. Note: since registry does reading in a lock-free manner, it is possible to have an inconsistent read snapshot of ordered items which may capture items that have already/not yet been added to the registry

Constructors

OrderedRegistry()

Declaration

OrderedRegistry(Boolean)

Declaration
public OrderedRegistry(bool caseSensitive)
Parameters
Type Name Description
System.Boolean caseSensitive

Properties

Item[Int32]

Tries to return an item by its position index in ordered set of items that this registry keeps. Null is returned when index is out of bounds. Note: since registry does reading in a lock-free manner, it is possible to have an inconsistent read snapshot of ordered items which may capture items that have already/not yet been added to the registry

Declaration
public T this[int index] { get; }
Parameters
Type Name Description
System.Int32 index
Property Value
Type Description
T

OrderedValues

Returns items that registry contains ordered by their Order property. The returned sequence is pre-sorted during alteration of registry, so this property access is efficient. Note: since registry does reading in a lock-free manner, it is possible to have an inconsistent read snapshot of ordered items which may capture items that have already/not yet been added to the registry

Declaration
public IEnumerable<T> OrderedValues { get; }
Property Value
Type Description
System.Collections.Generic.IEnumerable<T>
