Syntax

public static class ProtobufEqualityComparers

Properties

BitwiseDoubleEqualityComparer

Returns an equality comparer suitable for comparing 64-bit floating point values, by bitwise comparison. (NaN values are considered equal, but only when they have the same representation.)

Declaration

public static EqualityComparer<double> BitwiseDoubleEqualityComparer { get; }

Property Value

Type	Description
System.Collections.Generic.EqualityComparer<System.Double>

BitwiseNullableDoubleEqualityComparer

Returns an equality comparer suitable for comparing nullable 64-bit floating point values, by bitwise comparison. (NaN values are considered equal, but only when they have the same representation.)

Declaration

public static EqualityComparer<double?> BitwiseNullableDoubleEqualityComparer { get; }

Property Value

Type	Description
System.Collections.Generic.EqualityComparer<System.Nullable<System.Double>>

BitwiseNullableSingleEqualityComparer

Returns an equality comparer suitable for comparing nullable 32-bit floating point values, by bitwise comparison. (NaN values are considered equal, but only when they have the same representation.)

Declaration

public static EqualityComparer<float?> BitwiseNullableSingleEqualityComparer { get; }

Property Value

Type	Description
System.Collections.Generic.EqualityComparer<System.Nullable<System.Single>>

BitwiseSingleEqualityComparer

Returns an equality comparer suitable for comparing 32-bit floating point values, by bitwise comparison. (NaN values are considered equal, but only when they have the same representation.)

Declaration

public static EqualityComparer<float> BitwiseSingleEqualityComparer { get; }

Property Value

Type	Description
System.Collections.Generic.EqualityComparer<System.Single>

Methods

GetEqualityComparer<T>()

Returns an equality comparer for T suitable for Protobuf equality comparisons. This is usually just the default equality comparer for the type, but floating point numbers are compared bitwise.

Declaration

public static EqualityComparer<T> GetEqualityComparer<T>()

Returns

Type	Description
System.Collections.Generic.EqualityComparer<T>	The equality comparer.

Type Parameters

Name	Description
T	The type of equality comparer to return.
