TupleComparisons.CompositeComparer<T1, T2>

Namespace: SnowBank.Data.Tuples · class

Implements: IComparer<IVarTuple>, IComparer<STuple<T1, T2>>, IComparer<(T1, T2)>

Comparer that compares tuples with at least 2 items

Constructors

CompositeComparer<T1, T2>()

Constructor for a new tuple comparer

CompositeComparer<T1, T2>(IComparer<T1> comparer1, IComparer<T2> comparer2)

Constructor for a new tuple comparer

CompositeComparer<T1, T2>(int offset, IComparer<T1> comparer1, IComparer<T2> comparer2)

Constructor for a new tuple comparer

offset — Offset in the tuples of the first element to compare (can be negative)
comparer1 — Comparer for the first element type
comparer2 — Comparer for the second element type

IComparer<T1> Comparer1 { get; }

Comparer for the first element (at position Offset)

IComparer<T2> Comparer2 { get; }

Comparer for the second element (at position Offset + 1)

int Offset { get; }

Offset in the tuples where the comparison starts

If negative, comparison starts from the end.

int Compare(IVarTuple x, IVarTuple y)

Compare up to two items in both tuples

Returns: Returns a positive value if x is greater than y, a negative value if x is less than y and 0 if x is equal to y.

int Compare(STuple<T1, T2> x, STuple<T1, T2> y)

Compare two tuples

Returns: Returns a positive value if x is greater than y, a negative value if x is less than y and 0 if x is equal to y.

int Compare((T1, T2) x, (T1, T2) y)

Compare two tuples

Returns: Returns a positive value if x is greater than y, a negative value if x is less than y and 0 if x is equal to y.
