fun customizeSerialization(custom: SerializationCustomization): Boolean
Overrides CordaPluginRegistry.customizeSerialization
Optionally whitelist types for use in object serialization, as we lock down the types that can be serialized.
For example, if you add a new ContractState it needs to be whitelisted. You can do that either by adding the @CordaSerializable annotation or via this method.
Return
true if you register types, otherwise you will be filtered out of the list of plugins considered in future.
