You can write any non-TObject to a ROOT file, STL collection or ROOT
class like TArray.
For example, you can create a TArrayI object and write it to a file with:
root [0] TFile f("junk.root","recreate") root [1] TArrayI a[5] root [2] a[0]=0 root [3] a[1]=1 root [4] a[2]=2 root [5] a[3]=3 root [6] a[4]=4 root [7] f.WriteObjectAny(&a,"TArrayI","a")
For more details, read chapter about I/O in the Users Guide.
