LAL Standard Package - std LAL datatypes.h
Primitive datatypes▪ Atomic datatypes▪ Complex datatypes
Aggregate datatypes : Store arbitrarily large sets or collections of primitive datatypes. aggregate datatypes are defines : vectors, arrays, se-quences, vector sequences, and array sequences.
Structured datatypes : embed primitive and ag-gregate datatypes inside structures that define their physical meaning.
