template<typename V, size_t Size1, size_t Size2>

_VC_CONSTEXPR size_t ROOT::Vc::Memory< V, Size1, Size2 >::entriesCount ( ) const

inline

Returns: the number of scalar entries in the whole array.

Warning: Do not use this function for scalar iteration over the array since there will be padding between rows if Size2 is not divisible by V::Size.

Note: This function can be optimized into a compile-time constant.

Definition at line 163 of file memory.h.

template<typename Parent , typename RM >

Vc_ALWAYS_INLINE Memory& ROOT::Vc::Memory< V, Size1, Size2 >::operator= ( const MemoryBase< V, Parent, 2, RM > & rhs )

inline

Copies the data from a different object.

Parameters

rhs	The object to copy the data from.

Returns: reference to the modified Memory object.

Note: Both objects must have the exact same vectorsCount().
