Class BaseNetConfigDeserializer<T>

java.lang.Object

org.nd4j.shade.jackson.databind.JsonDeserializer<T>

org.nd4j.shade.jackson.databind.deser.std.StdDeserializer<T>

org.deeplearning4j.nn.conf.serde.BaseNetConfigDeserializer<T>

All Implemented Interfaces:

Serializable, org.nd4j.shade.jackson.databind.deser.ResolvableDeserializer

Direct Known Subclasses:

ComputationGraphConfigurationDeserializer, MultiLayerConfigurationDeserializer

public abstract class BaseNetConfigDeserializer<T>
extends org.nd4j.shade.jackson.databind.deser.std.StdDeserializer<T>
implements org.nd4j.shade.jackson.databind.deser.ResolvableDeserializer

A custom (abstract) deserializer that handles backward compatibility (currently only for updater refactoring that happened after 0.8.0). This is used for both MultiLayerConfiguration and ComputationGraphConfiguration.
We deserialize the config using the default deserializer, then handle the new IUpdater (which will be null for 0.8.0 and earlier configs) if necessary Overall design: http://stackoverflow.com/questions/18313323/how-do-i-call-the-default-deserializer-from-a-custom-deserializer-in-jackson
