Introduction

objarray is a special type of Tcl_Obj to handle efficiently (in memory and cpu) arrays of basic numeric types at Tcl level.
This package was developed at CIMNE (www.cimne.com ) mainly for GiD (http://www.gidsimulation.com), but is is implemented as an independent tcl package that can be used by other applications

To use it, it should be loaded load with

Tcl_Obj objects automatically do internal conversion between strings and its special type and vice-versa, this facilitate its use.

The hdf5 plugin uses internally objarrays as bridge between HDF5-like arrays and GiD data.

The vtkobjarray is another specialized Tcl package that act as link between objarrays and vtk-like arrays
(e.g. it is used by the GiD-vtk results import/export plugin)

Note: objarray, hdf5 and vtk_objarray are Tcl packages developed at CIMNE for GiD
