xtd::iequatable< type_t > Class Template Reference

#include <iequatable.h>

Definition

template<typename type_t>
class xtd::iequatable< type_t >

Defines a generalized method that a value type or class implements to create a type-specific method for determining equality of instances.

Namespace

xtd

Library

xtd.core

Remarks

This interface is implemented by types whose values can be equated (for example, the numeric and string classes). A value type or class implements the equals method to create a type-specific method suitable for determining equality of instances.

The icomparable<T> interface defines the compare_to method, which determines the sort order of instances of the implementing type. The iequatable<T> interface defines the equals method, which determines the equality of instances of the implementing type.

Member Function Documentation

equals() [1/2]

template<typename type_t>

virtual bool xtd::iequatable< type_t >::equals ( const type_t &  ) const

pure virtualnoexcept

Indicates whether the current object is equal to another object of the same type.

Parameters

obj	An object to compare with this object.

Returns

true if the current object is equal to the other parameter; otherwise, false.

Implemented in xtd::uri, xtd::date_time, xtd::time_zone_info, xtd::guid, and xtd::box< type_t >.

equals() [2/2]

template<typename type_t>

virtual bool xtd::iequatable< type_t >::equals ( const object &  ) const

pure virtualnoexcept

Indicates whether the current object is equal to another object of the same type.

Parameters

obj	An object to compare with this object.

Returns

true if the current object is equal to the other parameter; otherwise, false.
