BinaryPredicate is a set of requirements expected by some of the standard library facilities from the user-provided arguments.
Given a BinaryPredicate bin_pred
and a pair of iterators iter1
and iter2
or an iterator iter
and a value value
, the expression bin_pred(*iter1, *iter2)
or, respectively, bin_pred(*iter, value)
, must be contextually convertible to bool
.
In addition, evaluation of that expression is not allowed to call non-const member functions of the dereferenced iterators.
The following standard library facilities expect a BinaryPredicate which isn't a Compare type.
removes consecutive duplicate elements (public member function of std::forward_list<T,Allocator> ) |
|
removes consecutive duplicate elements (public member function of std::list<T,Allocator> ) |
|
finds the last sequence of elements in a certain range (function template) |
|
searches for any one of a set of elements (function template) |
|
finds the first two adjacent items that are equal (or satisfy a given predicate) (function template) |
|
finds the first position where two ranges differ (function template) |
|
determines if two sets of elements are the same (function template) |
|
(C++11) | determines if a sequence is a permutation of another sequence (function template) |
searches for a range of elements (function template) |
|
searches a range for a number of consecutive copies of an element (function template) |
|
removes consecutive duplicate elements in a range (function template) |
|
creates a copy of some range of elements that contains no consecutive duplicates (function template) |
|
(deprecated in C++17)(removed in C++20) | constructs custom std::binary_negate object (function template) |
(C++11) | collection of unique keys, hashed by keys (class template) |
(C++11) | collection of key-value pairs, hashed by keys, keys are unique (class template) |
(C++11) | collection of keys, hashed by keys (class template) |
(C++11) | collection of key-value pairs, hashed by keys (class template) |
