operator[]() [1/2]

template<typename T>

T& gf::BlockAllocator< T >::operator[] ( std::size_t  index )

inline

Access the object at a given index.

Parameters

index

A valid index

operator[]() [2/2]

template<typename T>

const T& gf::BlockAllocator< T >::operator[] ( std::size_t  index ) const

inline
