resize()

template<typename T >

void MayaFlux::Memory::HistoryBuffer< T >::resize ( size_t  new_capacity )

inline

Resize buffer capacity.

Parameters

new_capacity

New maximum number of samples

Preserves existing data in temporal order. If growing, new slots filled with zeros. If shrinking, oldest data discarded. Count always equals capacity after resize.
