Detailed Description

template<typename T>
struct Aleph::CA::Grid_Snapshot< T >

Dense numeric snapshot used by CSV and JSON readers.

Values are stored row-major. The type is deliberately small so callers can adapt it into Dense_Cell_Storage, an engine frame or a custom lattice.

Template Parameters

T	numeric cell type.

Member Function Documentation

at()

template<typename T >

T Aleph::CA::Grid_Snapshot< T >::at ( ca_size_t  row, ca_size_t  col  ) const

inline

Return the value at (row, col).

Parameters

[in]	row	row index.
[in]	col	column index.

Returns

value stored at that coordinate.

Exceptions

std::out_of_range

if the coordinate is outside the snapshot.

Complexity

O(1).
