NAME

Protocol::SPDY::Frame - support for SPDY frames

VERSION

version 1.001

DESCRIPTION

Support for SPDY frames. Typically you'd interact with these through the top-level Protocol::SPDY object.

See the Protocol::SPDY::Frame::Control and Protocol::SPDY::Frame::Data subclasses for the two currently-defined frame types.

METHODS

is_control

Returns true if this is a control frame. Recommended over checking ->isa(Protocol::SPDY::Frame::Control) directly.

is_data

Returns true if this is a data frame. Recommended over checking ->isa(Protocol::SPDY::Frame::Data) directly.

fin

Returns true if the FIN flag is set for this frame.

new

Instantiate a new frame. Typically called as a super method from the Protocol::SPDY::Frame::Control or Protocol::SPDY::Frame::Data subclass implementation.

length

Returns the length of the current packet in bytes.

type

Returns the numerical type of this frame, such as 1 for SYN_STREAM, 3 for RST_STREAM etc.

type_string

Returns the type of this frame as a string.

as_packet

Abstract method for returning the byte data comprising the SPDY packet that would hold this frame.

parse

Extract a frame from the given packet if possible. Takes a scalar reference to byte data, and returns a Protocol::SPDY::Frame subclass, or undef on failure.

version

Returns the version for this frame, probably 3.

extract_frame

Extracts a frame from the given data.

extract_headers

Given a scalar containing bytes, constructs an arrayref of headers and returns a 2-element list containing this arrayref and the length of processed data.

to_string

String representation of this frame, for debugging.
