Class TypeFromNodeAdaptor

java.lang.Object

Services.Dependencies.TypeFromNodeAdaptor

All Implemented Interfaces:

com.google.gson.JsonDeserializer<MyNode>

public class TypeFromNodeAdaptor
extends Object
implements com.google.gson.JsonDeserializer<MyNode>

Custom Gson deserializer for MyNode objects.

This deserializer handles polymorphic deserialization based on the presence of specific fields in the JSON. If the JSON object contains the field "ignorefirstLine", it is deserialized as a CSVNode; otherwise, it is deserialized as a regular MyNode.

This is useful for converting JSON representations of nodes in a dependency graph where some nodes may represent CSV data.
