AggregationExtensions Class​

Provides extension methods for aggregating values from objects based on specific comparable properties.

public static class AggregationExtensions

Inheritance System.Object → AggregationExtensions

Methods​

AggregationExtensions.Greater<T>(this Nullable<T>, Nullable<T>) Method​

Determines the greater of two nullable values, treating null as positive infinity.

public static System.Nullable<T> Greater<T>(this System.Nullable<T> accumulatorValue, System.Nullable<T> currentValue)
    where T : struct, System.IComparable<T>;

Type parameters​

T​

The type of the values being compared, constrained to value types that implement System.IComparable.

Parameters​

accumulatorValue System.Nullable<T>​

The first nullable value to compare.

currentValue System.Nullable<T>​

The second nullable value to compare.

Returns​

System.Nullable<T>
The greater of the two values if at least one is non-null; otherwise, null. If both values are non-null, the method returns null only if the currentValue is null, indicating it is considered as positive infinity.

Remarks​

This method is useful in scenarios where you're aggregating a collection of nullable values and consider the absence of a value (null) as the highest possible value, allowing for custom maximum value logic.

AggregationExtensions.Join<T>(this HashSet<T>, HashSet<T>) Method​

Combines the elements of two hash sets into a single set, including all unique elements from both.

public static System.Collections.Generic.HashSet<T>? Join<T>(this System.Collections.Generic.HashSet<T>? accumulator, System.Collections.Generic.HashSet<T>? current);

Type parameters​

T​

The type of elements in the hash sets.

Parameters​

accumulator System.Collections.Generic.HashSet<T>​

The first hash set.

current System.Collections.Generic.HashSet<T>​

The second hash set to combine with the first.

Returns​

System.Collections.Generic.HashSet<T>
A new hash set containing all unique elements from both input sets. If both inputs are null, returns null.

Remarks​

This method provides a convenient way to merge two sets of elements, ensuring that the result contains all distinct elements from both sets. It is particularly useful for combining collections of unique items without duplicating any elements.

AggregationExtensions.Lesser<T>(this Nullable<T>, Nullable<T>) Method​

Determines the lesser of two nullable values, treating null as negative infinity.

public static System.Nullable<T> Lesser<T>(this System.Nullable<T> currentValue, System.Nullable<T> accumulatorValue)
    where T : struct, System.IComparable<T>;

Type parameters​

T​

The type of the values being compared, constrained to value types that implement System.IComparable<>.

Parameters​

currentValue System.Nullable<T>​

The first nullable value to compare.

accumulatorValue System.Nullable<T>​

The second nullable value to compare.

Returns​

System.Nullable<T>
The lesser of the two values if at least one is non-null; otherwise, null. If both values are non-null, the method returns null only if the accumulatorValue is null, indicating it is considered as negative infinity.

Remarks​

This method supports scenarios requiring aggregation of a series of nullable values where the absence of a value (null) is interpreted as the lowest possible value, enabling custom minimum value logic.
