Class ProtobufEqualityComparers (3.27.1)

public static class ProtobufEqualityComparers

Provides a central place to implement equality comparisons, primarily for bitwise float/double equality.

Properties

BitwiseDoubleEqualityComparer

public static EqualityComparer<double> BitwiseDoubleEqualityComparer { get; }

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.)

Property Value
Type Description
EqualityComparerdouble

BitwiseNullableDoubleEqualityComparer

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

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.)

Property Value
Type Description
EqualityComparerdouble

BitwiseNullableSingleEqualityComparer

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

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.)

Property Value
Type Description
EqualityComparerfloat

BitwiseSingleEqualityComparer

public static EqualityComparer<float> BitwiseSingleEqualityComparer { get; }

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.)

Property Value
Type Description
EqualityComparerfloat

Methods

GetEqualityComparer<T>()

public static EqualityComparer<T> 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.

Returns
Type Description
EqualityComparer

The equality comparer.

Type Parameter
Name Description
T

The type of equality comparer to return.
