#define GOOGLE_PROTOBUF_UTIL_CONVERTER_EXPECTING_OBJECTWRITER_H__
// An implementation of ObjectWriter that automatically sets the
// gmock expectations for the response to a method. Every method
// returns the object itself for chaining.
//
// Usage:
// // Setup
// MockObjectWriter mock;
// ExpectingObjectWriter ow(&mock);
//
// // Set expectation
// ow.StartObject("")
// ->RenderString("key", "value")
// ->EndObject();
//
// // Actual testing
// mock.StartObject(StringPiece())
// ->RenderString("key", "value")
// ->EndObject();
