Class JsonGenerator

java.lang.Object

com.google.api.client.json.JsonGenerator

Direct Known Subclasses:

MockJsonGenerator

public abstract class JsonGenerator
extends Object

Abstract low-level JSON serializer.

Implementation has no fields and therefore thread-safe, but sub-classes are not necessarily thread-safe.
