Struct EqualityComparerBuilder<T>

Generates hash code and equality check functions for the particular type.

Inherited Members

ValueType.Equals(object)

ValueType.GetHashCode()

ValueType.ToString()

object.GetType()

object.Equals(object, object)

object.ReferenceEquals(object, object)

Namespace: DotNext

Assembly: DotNext.dll

Syntax

public readonly struct EqualityComparerBuilder<T>

Type Parameters

Name	Description
T	The type for which equality check and hash code functions should be generated.

Remarks

Automatically generated hash code and equality check functions can be used instead of manually written implementation of overridden GetHashCode() and Equals(object) methods.

Properties

ExcludedFields

Sets an array of excluded field names.

Declaration

public string[] ExcludedFields { init; }

Property Value

Type	Description
string[]	An array of excluded fields.

SaltedHashCode

Set a value indicating that hash code must be unique for each application instance.

Declaration

public bool SaltedHashCode { init; }

Property Value

Type	Description
bool	true to include randomized salt data into hashing; false to use data from memory only.

Methods

Build()

Generates implementation of equality comparer.

Declaration

[RequiresDynamicCode("Runtime binding requires dynamic code compilation")]
[RequiresUnreferencedCode("Dynamic code generation may be incompatible with IL trimming")]
public IEqualityComparer<T> Build()

Returns

Type	Description
IEqualityComparer<T>	The generated equality comparer.

Exceptions

Type	Condition
PlatformNotSupportedException	Dynamic code generation is not supported by underlying CLR implementation.

Build(out Func<T?, T?, bool>, out Func<T, int>)

Generates implementation of GetHashCode() and Equals(object) methods for particular type T.

Declaration

[RequiresDynamicCode("Runtime binding requires dynamic code compilation")]
[RequiresUnreferencedCode("Dynamic code generation may be incompatible with IL trimming")]
public void Build(out Func<T?, T?, bool> equals, out Func<T, int> hashCode)

Parameters

Type	Name	Description
Func<T, T, bool>	equals	The implementation of equality check.
Func<T, int>	hashCode	The implementation of hash code.

Exceptions

Type	Condition
PlatformNotSupportedException	Dynamic code generation is not supported by underlying CLR implementation.
