Serialization of an object graph includes class information as well as
instance information. If more than one instance of the same class is
serialized as separate serialization operations then the class
information exists more than once. To eliminate this inefficiency the
StoredClassCatalog
class will
store the class format for all database records of format
SerialFormat
. The
StoredClassCatalog must be opened within the environment before the
SerialFormat instances. Remember that if your databases will be running
within transactions you must open them within a transaction. Refer to
the shipment sample code for examples (the class
SampleDatabase in
examples_java/src/com/sleepycat/examples/bdb/shipment/basic/SampleDatabase.java
is a good place to start understanding how to setup this type of
environment).
