Emit a sequence with map
and tag
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
.
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 ]
Called when a map ends
Called before each event with line/column information.
Start emitting a YAML map with anchor
, tag
, an implicit
start and end, and style
.

Guesses the type of the data which have been inputed into the stream. The returned value is either BINARY
, ASCII
, or UNKNOWN
.

Returns the major part of File_Stat#dev
or nil
.
File.stat("/dev/fd1").dev_major #=> 2 File.stat("/dev/tty").dev_major #=> 5
Returns the major part of File_Stat#rdev
or nil
.
File.stat("/dev/fd1").rdev_major #=> 2 File.stat("/dev/tty").rdev_major #=> 5
Iterates over keys and objects in a weakly referenced object

Returns the absolute path of this instruction sequence.
nil
if the iseq was evaluated from a string.
For example, using ::compile_file
:
# /tmp/method.rb def hello puts "hello, world" end # in irb > iseq = RubyVM::InstructionSequence.compile_file('/tmp/method.rb') > iseq.absolute_path #=> /tmp/method.rb
Paths in the gem to add to $LOAD_PATH
when this gem is activated. If you have an extension you do not need to add "ext"
to the require path, the extension build process will copy the extension files into “lib” for you.
The default value is "lib"
Usage:
# If all library files are in the root directory... spec.require_paths = ['.']
Return the list of all array-oriented instance variables.
Return the list of all instance variables.
Return the latest specs, optionally including prerelease specs if prerelease
is true.

a required attribute?
