query_comments

Description:

public Feed? query_comments (Service service, Query? query, Cancellable? cancellable, QueryProgressCallback? progress_callback) throws Error

Retrieves a Feed containing the Comment s representing the comments on the Commentable which match the given query.

If the Commentable doesn't support commenting, null will be returned and throws will be set to gdata_service_error_forbidden. This is in contrast to if it does support commenting but hasn't had any comments added yet, in which case an empty Feed will be returned and no error will be set.

Parameters:

this	a Commentable
service	a Service representing the service with which the object's comments will be manipulated
query	a Query with query parameters, or null
cancellable	optional Cancellable object, or null
progress_callback	a QueryProgressCallback to call when a comment is loaded, or null
progress_user_data	data to pass to the `progress_callback` function

Returns:

a Feed of Comments, or null; unref with unref
