Emit a scalar with value
Called when an alias is found to anchor
. anchor
will be the name of the anchor found.
Here we have an example of an array that references itself in YAML:
--- &ponies - first element - *ponies
&ponies is the anchor, *ponies is the alias. In this case, alias is called with “ponies”.
Called when a scalar value
is found. The scalar may have an anchor
, a tag
, be implicitly plain
or implicitly quoted
value
is the string value of the scalar anchor
is an associated anchor or nil tag
is an associated tag or nil plain
is a boolean value quoted
is a boolean value style
is an integer indicating the string style
See the constants in Psych::Nodes::Scalar
for the possible values of style
Here is a YAML
document that exercises most of the possible ways this method can be called:
--- - !str "foo" - &anchor fun - many lines - | many newlines
The above YAML
document contains a list with four strings. Here are the parameters sent to this method in the same order:
# value anchor tag plain quoted style ["foo", nil, "!str", false, false, 3 ] ["fun", "anchor", nil, true, false, 1 ] ["many lines", nil, nil, true, false, 1 ] ["many\nnewlines\n", nil, nil, false, true, 4 ]
Emit a scalar with value
, anchor
, tag
, and a plain
or quoted
string type with style
.
Get the output style, canonical or not.
Set
the output style to canonical, or not.
Get the indentation level.
Set
the indentation level to level
. The level must be less than 10 and greater than 1.
Returns the exit status of the child for which PTY#check raised this exception
The scanner’s state of the current token. This value is the bitwise OR of zero or more of the Ripper::EXPR_*
constants.
returns the socket family as an integer.
p Socket::AncillaryData.new(:INET6, :IPV6, :PKTINFO, "").family #=> 10
returns the cmsg data as a string.
p Socket::AncillaryData.new(:INET6, :IPV6, :PKTINFO, "").data #=> ""
returns the timestamp as a time object.
ancillarydata should be one of following type:
SOL_SOCKET/SCM_TIMESTAMP (microsecond) GNU/Linux, FreeBSD, NetBSD, OpenBSD, Solaris, MacOS X
SOL_SOCKET/SCM_TIMESTAMPNS (nanosecond) GNU/Linux
SOL_SOCKET/SCM_BINTIME (2**(-64) second) FreeBSD
Addrinfo.udp
(“127.0.0.1”, 0).bind {|s1|
Addrinfo.udp("127.0.0.1", 0).bind {|s2| s1.setsockopt(:SOCKET, :TIMESTAMP, true) s2.send "a", 0, s1.local_address ctl = s1.recvmsg.last p ctl #=> #<Socket::AncillaryData: INET SOCKET TIMESTAMP 2009-02-24 17:35:46.775581> t = ctl.timestamp p t #=> 2009-02-24 17:35:46 +0900 p t.usec #=> 775581 p t.nsec #=> 775581000 }
}
Returns the destination address of ifaddr. nil is returned if the flags doesn’t have IFF_POINTOPOINT.
Sends the String
msg
to the source
returns the socket family as an integer.
p Socket::Option.new(:INET6, :IPV6, :RECVPKTINFO, [1].pack("i!")).family #=> 10
returns the socket option data as a string.
p Socket::Option.new(:INET6, :IPV6, :RECVPKTINFO, [1].pack("i!")).data #=> "\x01\x00\x00\x00"
return values as an array
Returns true if argument is optional.
