This would result in multiple definitions if this header is included in more than one translation units.

This eventually is a member variable of class ParticleContainer_impl, as this file is included in "AMReX_ParticleContainer.H".

Instead of plain text including this into another class, which will complicate our transition to C++ modules and is a bit surprising in general, consider making this a C++ mixin class:
https://en.wikipedia.org/wiki/Mixin
Simply derive ParticleContainer_impl from this.

The extra code in this file is a function that figures out ptl offsets for each processors. I think using mixin possibly will be an overkill, and clients need to change their code when initialing ParticleContainer_impl related classes.
Since this is only used by openPMD-api, I will move this function into the amex::openpmd_api scope. Leave the AMReX_ParticleContainer.H as is.

Just saw you pushed. Thanks. |
set default axis labels to be "x/y/z" for 1/2/3-Dims other behaviours should be done in application codes removed print statements

AMReX includes for ParallelDescriptor, ParallelGather, <vector> missing in this file.

This file is currently embedded in AMReX_ParticleContainer.H, which has all the included files declared already.

I would prefer if this was used as a mixin class instead of a textual include.
