Interface IDeepSecureEqualityComparer<T>

Namespace

Nerdbank.MessagePack

Assembly

Nerdbank.MessagePack.dll

An interface that may be implemented by user-defined types in order to provide their own deep (i.e. giving all values a chance to contribute) hash code.

public interface IDeepSecureEqualityComparer<T>

Type Parameters

T

The same type that is implementing this interface.

Remarks

When a type implements this interface, GetHashCode() and DeepEquals(T?) is used to determine equality and hash codes for the type by the ByValueEqualityComparer equality comparer instead of the deep by-value automatic implementation.

Methods

DeepEquals(T?)

Tests deep equality of this object with another object.

bool DeepEquals(T? other)

Parameters

other T

The other object.

Returns

bool

true if the two objects are deeply equal.

Remarks

An implementation may use GetDefault<T>(ITypeShape<T>) to obtain equality comparers for any sub-values that must be tested.

GetHashCode()

Gets a hash code for this object, which may not be collision resistant.

int GetHashCode()

Returns

int

A 32-bit integer.

Remarks

The default implementation of this method is to truncate the result of GetSecureHashCode().

GetSecureHashCode()

Gets a collision resistant hash code for this object.

long GetSecureHashCode()

Returns

long

A 64-bit integer.

Exceptions

NotSupportedException

May be thrown if not supported.
