Remarks

Common base class of AList{T} and SparseAList{T}. Most of the functionality of the two types is identical, so this class is used to share code between them.

This class exists for code sharing only. Clients should ignore it.

The difference between AListBase{K,T} and AListBase{T} is that the first one is the base class of all data structures in the A-List family (including BList{T}, BDictionary{K,V}, etc.) while the second one is only the base class of non-organized ALists (AList{T} and SparseAList{T}).

Member Function Documentation

bool Loyc.Collections.AListBase< T >.Contains ( T item )

inline

Returns true if-and-only-if the specified item exists in the list.

Implements Loyc.Collections.IContains< in T >.

void Loyc.Collections.AListBase< T >.DetectSizeOverflow ( int insertSize )

inlineprotected

Throws OverflowException if inserting the specified number of items would cause Count to overflow.

virtual int Loyc.Collections.AListBase< T >.IndexOf ( T item )

inlinevirtual

Finds an index of an item in the list.

Parameters

item	An item for which to search.

Returns: An index of the item.

The default implementation simply calls AListBase{K,T}.LinearScanFor. This method is called by Remove and Contains.

Reimplemented in Loyc.Collections.SparseAList< T >, and Loyc.Collections.IndexedAList< T >.

bool Loyc.Collections.AListBase< T >.Remove ( T item )

inline

Finds a specific item and removes it. If duplicates of the item exist, only the first occurrence is removed.

Returns: True if an item was removed, false if not.

new ListSlice<T> Loyc.Collections.AListBase< T >.Slice	(	int	start,
		int	count = `int.MaxValue`
	)

inline

Returns a sub-range of this list.

Parameters

start	The new range will start at this index in the current list (this location will be index [0] in the new range).
count	The desired number of elements in the new range, or int.MaxValue to get all elements until the end of the list.

Returns: Returns a sub-range of this range.

Exceptions

ArgumentException The start index was below zero.

The (start, count) range is allowed to be invalid, as long as start is zero or above.

If count is below zero, or if start is above the original Count, the Count of the new slice is set to zero.
if (start + count) is above the original Count, the Count of the new slice is reduced to this.Count - start. Implementation note: do not compute (start + count) because it may overflow. Instead, test whether (count > this.Count - start).

Most collections should use the following implementation:

IListSource<T> IListSource<T>.Slice(int start, int count) { return Slice(start, count); }
public Slice_<T> Slice(int start, int count) { return new Slice_<T>(this, start, count); }

Implements Loyc.Collections.IListSource< out T >.
