Detailed Description

template<typename T, typename Vector = SmallVector<T, 0>, typename Set = DenseSet<T>, unsigned N = 0>
class llvm::SetVector< T, Vector, Set, N >

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.

The key and value types are derived from the Set and Vector types respectively. This allows the vector-type operations and set-type operations to have different types. In particular, this is useful when storing pointers as "Foo *" values but looking them up as "const Foo *" keys.

No constraint is placed on the key and value types, although it is assumed that value_type can be converted into key_type for insertion. Users must be aware of any loss of information in this conversion. For example, setting value_type to float and key_type to int can produce very surprising results, but it is not explicitly disallowed.

The parameter N specifies the "small" size of the container, which is the number of elements upto which a linear scan over the Vector will be used when searching for elements instead of checking Set, due to it being better for performance. A value of 0 means that this mode of operation is not used, and is the default value.
