Inheritance diagram for Loyc.Collections.AListBase< K, T >.Enumerator:

Public fields
readonly uint	FirstIndex
readonly uint	StartIndex

Properties
int	CurrentIndex [get]
	Index of the last item that was enumerated. If has been enumerated yet, this will typically be one beyond the range of indexes with which this enumerator was initialized, e.g. -1 when enumerating the entire list from the beginning. More...
T	Current [get, set]
Properties inherited from Loyc.Collections.AListBase< K, T >
virtual ListChangingHandler< T >	ListChanging
	Event for learning about changes in progress on a list. More...
byte	TreeHeight [get]
int	Count [get]
bool	IsEmpty [get]
AListReverseView< K, T >	ReverseView [get]
T	this[int index] [get]
bool	IsFrozen [get]
T	First [get]
T	Last [get]
int	ObserverCount [get]
	Returns the number of tree observers attached to this list. More...

Public Member Functions inherited from Loyc.Collections.AListBase< K, T >
void	RemoveAt (int index)
void	RemoveRange (int index, int amount)
int	RemoveAll (Predicate< T > match)
	Removes all the elements that match the conditions defined by the specified predicate. More...
virtual void	Clear ()
IEnumerable< int >	IndexesOf (T item)
	Returns a sequence of integers that represent the locations where a given item appears in the list. More...
virtual IEnumerable< int >	IndexesOf (T item, int minIndex, int maxIndex)
int	LinearScanFor (T item, int startIndex, EqualityComparer< T > comparer)
	Scans the list starting at startIndex and going upward, and returns the index of an item that matches the first argument. More...
void	CopyTo (T[] array, int arrayIndex)
Enumerator	GetEnumerator ()
Enumerator	GetEnumerator (int startIndex)
Enumerator	GetEnumerator (int start, int subcount)
Enumerator	GetEnumerator (int start, int subcount, bool startAtEnd)
T	TryGet (int index, out bool fail)
	Gets the item at the specified index, and does not throw an exception on failure. More...
virtual void	Freeze ()
	Prevents further changes to the list. More...
Slice_< T >	Slice (int start, int length)
	Returns a sub-range of this list. More...
int	GetImmutableCount ()
	Diagnostic method. Returns the number of elements of the list that are located in immutable nodes, which will be copied if modified. Used by the test suite. More...
virtual bool	AddObserver (IAListTreeObserver< K, T > observer)
	Attaches a tree observer to this object. More...
virtual bool	RemoveObserver (IAListTreeObserver< K, T > observer)
	Removes a previously attached tree observer from this list. More...

Additional Inherited Members
Protected Member Functions inherited from Loyc.Collections.AListBase< K, T >
	AListBase (int maxLeafSize)
	AListBase (int maxLeafSize, int maxInnerSize)
	AListBase (AListBase< K, T > items, bool keepListChangingHandlers)
	Cloning constructor. Does not duplicate the observer (IAListTreeObserver{K,T}), if any, because it may not be cloneable. More...
	AListBase (AListBase< K, T > original, AListNode< K, T > section)
	This is the constructor that CopySection(), which can be defined by derived classes, should call to create a sublist of a list. Used in conjunction with CopySectionHelper(). More...

AListNode< K, T >	CopySectionHelper (int start, int subcount)
	Together with the AListBase{K,T}.AListBase(AListBase{K,T},AListNode{K,T}) constructor, this method helps implement the CopySection() method in derived classes, by cloning a section of the tree. More...

get

Index of the last item that was enumerated. If has been enumerated yet, this will typically be one beyond the range of indexes with which this enumerator was initialized, e.g. -1 when enumerating the entire list from the beginning.
