Summary

Exposes an IEnumerable<T> as an IList<T>, enabling buffering of and indexing into the elements generated by the enumerable, while still ensuring that the enumerable is enumerated in a lazy fashion, only as required, and at most once. This collection is read-only, and all write-related methods throw a NotSupportedException.

Generic type parameters

T	Type of the elements in the enumeration.

Constructors

LazyList<T>(IEnumerable<T> enumerable)

Constructor.

Instance methods

bool	Contains(T item) Implements: ICollection<T>.Contains(T)	Determines whether an element is in the list.
void	CopyTo(T[] array, int arrayIndex) Implements: ICollection<T>.CopyTo(T[], int)	Copies all elements to the specified array starting at the specified index.
void	Dispose() Implements: IDisposable.Dispose()	Disposes of the enumerable's enumerator, if one is held at the moment.
IEnumerator<T>	GetEnumerator() Implements: IEnumerable<T>.GetEnumerator()	Returns an enumerator for the collection. Warning: This enumerates the underlying collection completely before returning.
bool	IndexInRange(int index)	Checks whether the specified index is a valid index, i.e. not out-of-range.
int	IndexOf(T item) Implements: IList<T>.IndexOf(T)	Returns the index of the specified item, or -1 if the item is not found. (see also remarks)

Instance properties

int	Count Implements: ICollection<T>.Count	Gets the number of elements. Note that this method will have to enumerate the underlying enumerable in full.
bool	IsReadOnly	Returns true.
T	this[int index]	Gets the item at the specified index.
