Methods

AddProperty(Object, Object)

CompareExchange<T>(Object, T, T)

Compares the entry associated with key for equality with value and, if they are Equals(Object, Object), replaces the entry with value. This is done as a thread-safe/atomic operation.

GetOrCreateSingletonProperty<T>(Func<T>)

Gets or creates a property of type T from the property collection. If there is already a property of that type, it returns the existing property. Otherwise, it uses creator to create an instance of that type.

GetOrCreateSingletonProperty<T>(Object, Func<T>)

Gets or creates a property of type T from the property collection. If there is already a property with the specified key, returns the existing property. Otherwise, uses creator to create an instance of that type and add it to the collection with the specified key.
