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
.
Builds a methods for level meth
.
Enumerate values.
Enumerate subkeys.
subkey is String
which contains name of subkey. wtime is last write time as FILETIME (64-bit integer). (see Registry.wtime2time
)
Guesses the type of the data which have been inputed into the stream. The returned value is either BINARY
, ASCII
, or UNKNOWN
.
See Zlib::GzipReader
documentation for a description.

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
Iterates over keys and objects in a weakly referenced object
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
