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.
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 with the document ends. implicit
is a boolean value indicating whether or not the document has an implicit ending.
Given the following YAML:
--- hello world
implicit
will be true. Given this YAML:
--- hello world ...
implicit
will be false.
Called when the YAML stream ends
Parse and return an int from string
Handles start_document
events with version
, tag_directives
, and implicit
styling.
Handles end_document
events with version
, tag_directives
, and implicit
styling.
The entry point of the parser. This method is used with next_token
. If Racc
wants to get token (and its value), calls next_token.
Example:
def parse @q = [[1,1], [2,2], [3,3], [false, '$']] do_parse end def next_token @q.shift end
Guesses the type of the data which have been inputed into the stream. The returned value is either BINARY
, ASCII
, or UNKNOWN
.
Returns true if the stream is finished.
Sets the preset dictionary and returns string
. This method is available just only after Zlib::Deflate.new
or Zlib::ZStream#reset
method was called. See zlib.h for details.
Can raise errors of Z_STREAM_ERROR if a parameter is invalid (such as NULL dictionary) or the stream state is inconsistent, Z_DATA_ERROR if the given dictionary doesn’t match the expected one (incorrect adler32 value)
Provide the inflate stream with a dictionary that may be required in the future. Multiple dictionaries may be provided. The inflate stream will automatically choose the correct user-provided dictionary based on the stream’s required dictionary.
Sets the preset dictionary and returns string
. This method is available just only after a Zlib::NeedDict
exception was raised. See zlib.h for details.
See Zlib::GzipReader
documentation for a description.
Iterates over keys and objects in a weakly referenced object
Returns serialized iseq binary format data as a String object. A corresponding iseq object is created by RubyVM::InstructionSequence.load_from_binary()
method.
String extra_data will be saved with binary data. You can access this data with RubyVM::InstructionSequence.load_from_binary_extra_data(binary)
.
Note that the translated binary data is not portable. You can not move this binary data to another machine. You can not use the binary data which is created by another version/another architecture of Ruby.
The mixed mode default is to treat a list of indices as row access, returning the rows indicated. Anything else is considered columnar access. For columnar access, the return set has an Array for each row with the values indicated by the headers in each Array. You can force column or row mode using by_col
!() or by_row
!().
You cannot mix column and row access.
Creates a DRb::DRbObject
given the reference information to the remote host uri
and object ref
.
