Detailed Description

template<typename PtrType>
class llvm::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.

Remove pointer from the set.

Returns whether the pointer was in the set. Invalidates iterators if true is returned. To remove elements while iterating over the set, use remove_if() instead.

Insert the given pointer with an iterator hint that is ignored.

This is identical to calling insert(Ptr), but allows SmallPtrSet to be used by std::insert_iterator and std::inserter().

insert() [3/4]

template<typename PtrType >

std::pair< iterator, bool > llvm::SmallPtrSetImpl< PtrType >::insert ( PtrType  Ptr )

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.

template<typename UnaryPredicate >

bool llvm::SmallPtrSetImpl< PtrType >::remove_if ( UnaryPredicate  P )

inline

Remove elements that match the given predicate.

This method is a safe replacement for the following pattern, which is not valid, because the erase() calls would invalidate the iterator:

for (PtrType *Ptr : Set)
  if (Pred(P))
    Set.erase(P);

Returns whether anything was removed. It is safe to read the set inside the predicate function. However, the predicate must not modify the set itself, only indicate a removal by returning true.
