 """Request a channel close This method indicates that the sender wants to close the channel. This may be due to internal conditions (e.g. a forced shut-down) or due to an error handling a specific method, i.e. an exception. When a close is due to an exception, the sender provides the class and method id of the method which caused the exception. RULE: After sending this method any received method except Channel.Close-OK MUST be discarded. RULE: The peer sending this method MAY use a counter or timeout to detect failure of the other peer to respond correctly with Channel.Close-OK.. PARAMETERS: reply_code: short The reply code. The AMQ reply codes are defined in AMQ RFC 011. reply_text: shortstr The localised reply text. This text can be logged as an aid to resolving issues. class_id: short failing method class When the close is provoked by a method exception, this is the class of the method. method_id: short failing method ID When the close is provoked by a method exception, this is the ID of the method.
