Class _GsonUtil

java.lang.Object

proguard.optimize.gson._GsonUtil

public final class _GsonUtil
extends Object

This utility class is injected into the program class pool when the GSON optimizations are applied. It contains the logic for picking the right type adapter for a given type and value that needs to be serialized. The injected toJson() methods in the domain classes will use these utility methods for serializing the fields of the domain class with the appropriate type adapter.
