Detailed Description

Functor that fills the elements of the particle array inexflag with the value of the spatial array bmasks, at the corresponding particle position.

Contrary to fillBufferFlag, here this is done only for the particles that the last elements of particle_indices point to (from the element at index start_index in particle_indices, to the last element of particle_indices)

Parameters

[in]	pti	Contains information on the particle positions
[in]	bmasks	Spatial array, that contains a flag indicating whether each cell is part of the gathering/deposition buffers
[out]	inexflag	Vector to be filled with the value of bmasks
[in]	geom	Geometry object, necessary to locate particles within the array bmasks
[in]	start_index	Index that which elements start to be modified
