Member Function Documentation

bool Loyc.Collections.ListSourceAsSparse< T >.IsSet ( int  index)
inline

Determines whether a value exists at the specified index.

Parameters
index
Returns
true if a value is assigned at the specified index, or false if index is part of an empty space, or is outside the range of indexes that exist.

Implements Loyc.Collections.ISparseListSource< T >.

T Loyc.Collections.ListSourceAsSparse< T >.NextHigherItem ( ref int?  index)
inline

Increases index by at least one to reach the next index that is not classified as empty space, and returns the item at that index.

Parameters
indexThis parameter is increased by at least one, and perhaps more than one so that it refers to an index where there is a value. If index is null upon entering this method, the first non-empty space in the list is found. If there are no values at higher indexes, if the list is empty or if index + 1 >= Count, index is null when the method returns.

This method must skip over all indexes i for which IsSet(i) returns false, and return the next index for which IsSet(i) returns true. This method must accept any integer as input, including invalid indexes.

Implements Loyc.Collections.ISparseListSource< T >.

T Loyc.Collections.ListSourceAsSparse< T >.NextLowerItem ( ref int?  index)
inline

Decreases index by at least one to reach the next index that is not classified as empty space, and returns the item at that index.

Parameters
indexThis parameter is increased by at least one, and perhaps more than one so that it refers to an index where there is a value. If index is null upon entering this method, the last non-empty space in the list is found. If there are no values at lower indexes, if the list is empty or if index is 0 or less, index is null when the method returns.

This method must skip over all indexes i for which IsSet(i) returns false, and return the next index for which IsSet(i) returns true. This method must accept any integer as input, including invalid indexes.
