Detailed Description

template<typename PtrType>
class wpi::SmallPtrSetImpl< PtrType >

A templated base class for SmallPtrSet which provides the typesafe interface that is common across all small sizes.

This is particularly useful for passing around between interface boundaries to avoid encoding a particular small size in the interface boundary.

Member Function Documentation

template<typename PtrType>
bool wpi::SmallPtrSetImpl< PtrType >::erase ( PtrType  Ptr)
inline

erase - If the set contains the specified pointer, remove it and return true, otherwise return false.

template<typename PtrType>
std::pair<iterator, bool> wpi::SmallPtrSetImpl< PtrType >::insert ( PtrType  Ptr)
inline

Inserts Ptr if and only if there is no element in the container equal to Ptr.

The bool component of the returned pair is true if and only if the insertion takes place, and the iterator component of the pair points to the element equal to Ptr.
