Returns the function that maps data point to its position.

◆ dataSize()

virtual Size2 jet::ScalarGrid2::dataSize ( ) const

pure virtual

Returns the size of the grid data.

This function returns the size of the grid data which is not necessarily equal to the grid resolution if the data is not stored at cell-center.

Implemented in jet::VertexCenteredScalarGrid2, and jet::CellCenteredScalarGrid2.
