The Stream package contains tools for streaming wrapped Sire objects, i.e. objects from BioSimSpace._SireWrappers.


save(sire_object, filebase)

Stream a wrapped Sire object to file.


Stream a wrapped Sire object from file.


Stream a System object to and from file.

 import BioSimSpace as BSS

 files = BSS.IO.expand(BSS.tutorialUrl(), ["", "ala.crd"], ".bz2")

 # Load a molecular system.
 system0 = BSS.IO.readMolecules(files)

 # Stream to file., "system")

 # Alternatively, stream the system object directly."system")

 # Stream from file.
 system1 = BSS.Stream.load("system.s3")

 # Check the metadata associated with an existing stream. Streaming is
 # generally backwards compatible, but it can be useful to know check
 # the data if issues occur, or when you require an object from a specific
 # sandpit.
