`class DataFrame`

DATA frames convey arbitrary, variable-length sequences of octets associated with a stream. One or more DATA frames are used, for instance, to carry HTTP request or response payloads.

DATA frames MAY also contain padding. Padding can be added to DATA frames to obscure the size of messages.

Definitions

`def end_stream?`

Check if this frame marks the end of the stream.

Signature

returns　Boolean: True if the END_STREAM flag is set.

Implementation

def end_stream?
	flag_set?(END_STREAM)
end

`def pack(data, *arguments, **options)`

Pack data into the frame, handling empty data as stream end.

Signature

parameter　data　String | Nil: The data to pack into the frame.
parameter　arguments　Array: Additional arguments passed to super.
parameter　options　Hash: Additional options passed to super.

Implementation

def pack(data, *arguments, **options)
	if data
		super
	else
		@length = 0
		set_flags(END_STREAM)
	end
end

`def apply(connection)`

Apply this DATA frame to a connection for processing.

Signature

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

Implementation

def apply(connection)
	connection.receive_data(self)
end

`def inspect`

Provide a readable representation of the frame for debugging.

Signature

returns　String: A formatted string representation of the frame.

Implementation

def inspect
	"\#<#{self.class} stream_id=#{@stream_id} flags=#{@flags} #{@length || 0}b>"
end
