Detailed Description

template<class T, size_t Align = AlignOf<T>::Alignment>
class llvm::ArrayRecycler< T, Align >::Capacity

The size of an allocated array is represented by a Capacity instance.

This class is much smaller than a size_t, and it provides methods to work with the set of legal array capacities.

unsigned llvm::ArrayRecycler< T, Align >::Capacity::getBucket ( ) const

inline

Get the bucket number for this capacity.

Capacity llvm::ArrayRecycler< T, Align >::Capacity::getNext ( ) const

inline

Get the next larger capacity. Large capacities grow exponentially, so this function can be used to reallocate incrementally growing vectors in amortized linear time.

template<class T, size_t Align = AlignOf<T>::Alignment>

size_t llvm::ArrayRecycler< T, Align >::Capacity::getSize ( ) const

inline

Get the number of elements in an array with this capacity.
