Constructor & Destructor Documentation

PooledAllocator()

nanoflann::PooledAllocator::PooledAllocator ( const size_t  blocksize_ = BLOCKSIZE )

inline

Default constructor.

Initializes a new pool.

Definition at line 485 of file nanoflann.hpp.

~PooledAllocator()

nanoflann::PooledAllocator::~PooledAllocator ( )

inline

Destructor.

Frees all the memory allocated in this pool.

allocate()

template<typename T >

T * nanoflann::PooledAllocator::allocate ( const size_t  count = 1 )

inline

Allocates (using this pool) a generic type T.

Params: count = number of instances to allocate. Returns: pointer (of type T*) to memory buffer
