Method Details

error

public void error(@Nonnull
 Resource objectId,
 int code,
 @Nonnull
 String message)

fatal error event

The error event is sent out when a fatal (non-recoverable) error has occurred. The object_id argument is the object where the error occurred, most often in response to a request to that object. The code identifies the error and is defined by the object interface. As such, each interface defines its own set of error codes. The message is a brief description of the error, for (debugging) convenience.

Parameters:

objectId - object where the error occurred

code - error code

message - error description

deleteId

public void deleteId(int id)

acknowledge object ID deletion

This event is used internally by the object ID management logic. When a client deletes an object that it had created, the server will send this event to acknowledge that it has seen the delete request. When the client receives this event, it will know that it can safely reuse the object ID.

Parameters:

id - deleted object ID
