IPC_MESSAGE_ROUTED2(GinJavaBridgeMsg_AddNamedObject,

IPC_MESSAGE_ROUTED1(GinJavaBridgeMsg_RemoveNamedObject,

// Sent from renderer to browser to get information about methods of

// objects is enabled on the browser side.
IPC_SYNC_MESSAGE_ROUTED1_1(GinJavaBridgeHostMsg_GetMethods,
int32 /* object_id */,
std::set<std::string> /* returned_method_names */)
// Sent from renderer to browser to find out, if an object has a method with

IPC_SYNC_MESSAGE_ROUTED2_1(GinJavaBridgeHostMsg_HasMethod,
int32 /* object_id */,
std::string /* method_name */,
bool /* result */)
// Sent from renderer to browser to invoke a method. Method arguments
// are chained into |arguments| list. base::ListValue is used for |result| as
// a container to work around immutability of base::Value.
// Empty result list indicates that an error has happened on the Java side
// (either bridge-induced error or an unhandled Java exception) and an exception
// must be thrown into JavaScript. |error_code| indicates the cause of
// the error.
// Some special value types that are not supported by base::Value are encoded
// as BinaryValues via GinJavaBridgeValue.

// Sent from renderer to browser in two cases:
//
// 1. (Main usage) To inform that the JS wrapper of the object has
// been completely dereferenced and garbage-collected.
//
// 2. To notify the browser that wrapper creation has failed. The browser side
// assumes optimistically that every time an object is returned from a
// method, the corresponding wrapper object will be successfully created on
// the renderer side. Sending of this message informs the browser whether
// this expectation has failed.
