Emit a sequence with map and tag

Emit an arbitrary object obj and tag

Called with encoding when the YAML stream starts. This method is called once per stream. A stream may contain multiple documents.

See the constants in Psych::Parser for the possible values of encoding.

Called when the document starts with the declared version, tag_directives, if the document is implicit.

version will be an array of integers indicating the YAML version being dealt with, tag_directives is a list of tuples indicating the prefix and suffix of each tag, and implicit is a boolean indicating whether the document is started implicitly.

Example

Given the following YAML:

%YAML 1.1
%TAG ! tag:tenderlovemaking.com,2009:
--- !squee

The parameters for start_document must be this:

version         # => [1, 1]
tag_directives  # => [["!", "tag:tenderlovemaking.com,2009:"]]
implicit        # => false

Called when a sequence ends.

Called when a map starts.

anchor is the anchor associated with the map or nil. tag is the tag associated with the map or nil. implicit is a boolean indicating whether or not the map was implicitly started. style is an integer indicating the mapping style.

See the constants in Psych::Nodes::Mapping for the possible values of style.

Example

Here is a YAML document that exercises most of the possible ways this method can be called:

---
k: !!map { hello: world }
v: &pewpew
  hello: world

The above YAML document consists of three maps, an outer map that contains two inner maps. Below is a matrix of the parameters sent in order to represent these three maps:

# anchor    tag                       implicit  style
[nil,       nil,                      true,     1     ]
[nil,       "tag:yaml.org,2002:map",  false,    2     ]
["pewpew",  nil,                      true,     1     ]

Handles start_document events with version, tag_directives, and implicit styling.

See Psych::Handler#start_document

Start a stream emission with encoding

See Psych::Handler#start_stream

Start a document emission with YAML version, tags, and an implicit start.

See Psych::Handler#start_document

End sequence emission.

See Psych::Handler#end_sequence

Start emitting a YAML map with anchor, tag, an implicit start and end, and style.

See Psych::Handler#start_mapping

This method is called when some event handler is undefined. event is :on_XXX, token is the scanned token, and data is a data accumulator.

The return value of this method is passed to the next event handler (as of Enumerable#inject).

Returns new ancillary data for IP_PKTINFO.

If spec_dst is not given, addr is used.

IP_PKTINFO is not standard.

Supported platform: GNU/Linux

addr = Addrinfo.ip("127.0.0.1")
ifindex = 0
spec_dst = Addrinfo.ip("127.0.0.1")
p Socket::AncillaryData.ip_pktinfo(addr, ifindex, spec_dst)
#=> #<Socket::AncillaryData: INET IP PKTINFO 127.0.0.1 ifindex:0 spec_dst:127.0.0.1>

Extracts addr, ifindex and spec_dst from IP_PKTINFO ancillary data.

IP_PKTINFO is not standard.

Supported platform: GNU/Linux

addr = Addrinfo.ip("127.0.0.1")
ifindex = 0
spec_dest = Addrinfo.ip("127.0.0.1")
ancdata = Socket::AncillaryData.ip_pktinfo(addr, ifindex, spec_dest)
p ancdata.ip_pktinfo
#=> [#<Addrinfo: 127.0.0.1>, 0, #<Addrinfo: 127.0.0.1>]
