Constructor & Destructor Documentation

◆ PooledAllocator()

nanoflann::PooledAllocator::PooledAllocator ( )
inline

Default constructor.

Initializes a new pool.

Definition at line 489 of file nanoflann.hpp.

◆ ~PooledAllocator()

◆ 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
