Results for: "slice"

Called when a sequence is started.

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

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

Example

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

---
- !!seq [
  a
]
- &pewpew
  - b

The above YAML document consists of three lists, an outer list that contains two inner lists. Here is a matrix of the parameters sent to represent these lists:

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

Called when a sequence ends.

Start emitting a sequence with anchor, a tag, implicit sequence start and end, along with style.

See Psych::Handler#start_sequence

End sequence emission.

See Psych::Handler#end_sequence

Get the preferred line width.

Set the preferred line with to width.

Duplicates the deflate stream.

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.

Returns the number of the first source line where the instruction sequence was loaded from.

For example, using irb:

iseq = RubyVM::InstructionSequence.compile('num = 1 + 2')
#=> <RubyVM::InstructionSequence:<compiled>@<compiled>>
iseq.first_lineno
#=> 1

Return trace points in the instruction sequence. Return an array of [line, event_symbol] pair.

It returns recorded script lines if it is availalble. The script lines are not limited to the iseq range, but are entire lines of the source file.

Note that this is an API for ruby internal use, debugging, and research. Do not use this for any other purpose. The compatibility is not guaranteed.

Calls superclass method.

Returns true if SSL/TLS is being used with HTTP.
