An implementation of IComparer<T> and IEqualityComparer<T> to compare IReadOnlyForeignKey instances.

This type is typically used by database providers (and other extensions). It is generally not used in application code.

public sealed class ForeignKeyComparer : System.Collections.Generic.IComparer<Microsoft.EntityFrameworkCore.Metadata.IForeignKey>, System.Collections.Generic.IEqualityComparer<Microsoft.EntityFrameworkCore.Metadata.IForeignKey>

public sealed class ForeignKeyComparer : System.Collections.Generic.IComparer<Microsoft.EntityFrameworkCore.Metadata.IReadOnlyForeignKey>, System.Collections.Generic.IEqualityComparer<Microsoft.EntityFrameworkCore.Metadata.IReadOnlyForeignKey>

type ForeignKeyComparer = class
    interface IEqualityComparer<IForeignKey>
    interface IComparer<IForeignKey>

    interface IEqualityComparer<IReadOnlyForeignKey>
    interface IComparer<IReadOnlyForeignKey>

Methods

Compare(IForeignKey, IForeignKey)	Compares two objects and returns a value indicating whether one is less than, equal to, or greater than the other.
Compare(IReadOnlyForeignKey, IReadOnlyForeignKey)	Compares two objects and returns a value indicating whether one is less than, equal to, or greater than the other.
Equals(IForeignKey, IForeignKey)	Determines whether the specified objects are equal.
Equals(IReadOnlyForeignKey, IReadOnlyForeignKey)	Determines whether the specified objects are equal.
GetHashCode(IForeignKey)	Returns a hash code for the specified object.
GetHashCode(IReadOnlyForeignKey)	Returns a hash code for the specified object.
