`class GoawayFrame`

The GOAWAY frame is used to initiate shutdown of a connection or to signal serious error conditions. GOAWAY allows an endpoint to gracefully stop accepting new streams while still finishing processing of previously established streams. This enables administrative actions, like server maintenance.

Definitions

`def connection?`

Check if this frame applies to the connection level.

Signature

returns　Boolean: Always returns true for GOAWAY frames.

Implementation

def connection?
	true
end

`def unpack`

Unpack the GOAWAY frame payload.

Signature

returns　Array: Last stream ID, error code, and debug data.

Implementation

def unpack
	data = super
	
	last_stream_id, error_code = data.unpack(FORMAT)
	
	return last_stream_id, error_code, data.slice(8, data.bytesize-8)
end

`def pack(last_stream_id, error_code, data)`

Pack GOAWAY frame data into payload.

Signature

parameter　last_stream_id　Integer: The last processed stream ID.
parameter　error_code　Integer: The error code for connection termination.
parameter　data　String: Additional debug data.

Implementation

def pack(last_stream_id, error_code, data)
	super [last_stream_id, error_code].pack(FORMAT) + data
end

`def apply(connection)`

Apply this GOAWAY frame to a connection for processing.

Signature

parameter　connection　Connection: The connection to apply the frame to.

Implementation

def apply(connection)
	connection.receive_goaway(self)
