# Construct or parse outgoing WebSocket Frame.
# @note You should NEVER use this class directly - use Client or Server subclasses instead, as they contain additional frame options(i.e. Client-side masking in draft 04)
#
# @example
# frame = WebSocket::Frame::Outgoing::Server.new(version: @handshake.version, data: "Hello", type: :text)
# frame.to_s # "\x81\x05\x48\x65\x6c\x6c\x6f"
class Outgoing < Base

autoload :Server, "#{::WebSocket::ROOT}/websocket/frame/outgoing/server"

# @return [Boolean] true if frame type is supported
def supported?
support_type?
end
# Should current frame be sent? Exclude empty frames etc.
# @return [Boolean] true if frame should be sent
def require_sending?
!error?
end
# Return raw frame formatted for sending.
