The ClaDb class provides 6 iterators:
“each_material” iterates on the materials storage and produces pairs of identifier and ClaMat object.
“each_materialId” iterates on the materials storage and produces the identifiers only.
“each_laminate” iterates on the laminates storage and produces pairs of identifier and ClaLam object.
“each_laminateId” iterates on the laminates storage and produces the identifiers only.
“each_load” iterates on the loads storage and produces pairs of identifier and ClaLoad object.
“each_loadId” iterates on the loads storage and produces the identifiers only.
These iterators have no argument.
