# An example hook script to check the commit log message.
# Called by "git commit" with one argument, the name of the file
# that has the commit message.  The hook should exit with non-zero
# status after issuing an appropriate message if it wants to stop the
# commit.  The hook is allowed to edit the commit message file.
#
# To enable this hook, rename this file to "commit-msg".

• SL = serialization library.
• SC = SerializationContext
• DC = DeserializationContext

SerializationContext.getReference()

Add method SerializationContext.getReference(Instance instance) to get the SerializableReference of an already registered instance:
