using xtd::collections::iequality_comparer = typedef generic::iequality_comparer<xtd::any_object>

Remarks

This interface allows the implementation of customized equality comparison for collections. That is, you can create your own definition of equality, and specify that this definition be used with a collection type that accepts the xtd::collections::iequality_comparer interface. In the xtd framework, constructors of the xtd::collections::hashtable, xtd::collections::specialized::name_value_collection, and xtd::collections::specialized::ordered_dictionary collection types accept this interface.

For the generic version of this interface, see xtd::collections::generic::iequality_comparer <type_t>.

The xtd::collections::iequality_comparer interface supports only equality comparisons. Customization of comparisons for sorting and ordering is provided by the xtd::collections::icomparer interface.
