Using a Custom Class

This example shows how to use the defined BankAccount custom key type and the AccountHistory value type.

The example takes you through these basic operations: registering, creating a cache, connecting to the distributed system, putting data, getting data, and closing the cache.

Using a BankAccount Object

This example connects, registers types, creates the cache, creates a
region, and then puts and gets user defined type BankAccount.
