Whole document tree equal_to<T>
DescriptionEqual_to<T> is a function object. Specifically, it is an Adaptable Binary Predicate, which means it is a function object that tests the truth or falsehood of some condition. If f is an object of class equal_to<T> and x and y are objects of class T, then f(x,y) returns true if x == y and false otherwise.ExampleRearrange a vector such that all of the elements that are equal to zero precede all nonzero elements.vector<int> V; ... partition(V.begin(), V.end(), bind2nd(equal_to<int>(), 0)); DefinitionDefined in the standard header functional, and in the nonstandard backward-compatibility header function.h.Template parameters
