Detailed Description

template<typename T, typename Vector = std::vector<T>, typename Set = DenseSet<T>>
class llvm::SetVector< T, Vector, Set >

A vector that has set insertion semantics.

This adapter class provides a way to keep a set of things that also has the property of a deterministic iteration order. The order of iteration is the order of insertion.

Remove items from the set vector based on a predicate function.

This is intended to be equivalent to the following code, if we could write it:

V.erase(remove_if(V, P), V.end());

However, SetVector doesn't expose non-const iterators, making any algorithm like remove_if impossible to use.

Returns: true if any element is removed.
