  5. LAL Standard Package • Std : contains headers providing basic datatypes, constants, and macros that support the LAL standard. • Sample : contains templates for LAL headers and modules, as well as fully - autodocumenting example program based on the primer in the std package. 5th Korea-Japan Joint Meeting on GW

  6. 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, sequences, vector sequences, and array sequences. • Structured datatypes : embed primitive and aggregate datatypes inside structures that define their physical meaning. 5th Korea-Japan Joint Meeting on GW

  7. General Package • Date : providing routines related to date and time manipulations. • Factories : providing routines for creating ad destroying the LAL aggregate datatypes. • Tools : contains the general purpose LAL tools. • Vectorops : contains routines or manipulating vectors. 5th Korea-Japan Joint Meeting on GW
