Results for: "Array.new"

Generates a cryptographically strong pseudo-random number of bits.

See also the man page BN_rand(3).

Parses a given string as a blob that contains configuration for OpenSSL.

Returns an array of currently loaded engines.

Emit a scalar with value

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

Example

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    ]

Parse the YAML document contained in yaml. Events will be called on the handler set on the parser instance.

See Psych::Parser and Psych::Parser#handler

Returns a Psych::Parser::Mark object that contains line, column, and index information.

Emit a scalar with value, anchor, tag, and a plain or quoted string type with style.

See Psych::Handler#scalar

The line number of the current token. This value starts from 1. This method is valid only in event handlers.

Starts the parser. init is a data accumulator and is passed to the next event handler (as of Enumerable#inject).

Returns the netmask address of ifaddr. nil is returned if netmask is not available in ifaddr.

Logs a message at the error (syslog warning) log level, or logs the message returned from the block.

Logs a message at the warn (syslog notice) log level, or logs the message returned from the block.

Returns array of WIN32OLE_VARIABLE objects which represent variables defined in OLE class.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'XlSheetType')
vars = tobj.variables
vars.each do |v|
  puts "#{v.name} = #{v.value}"
end

The result of above sample script is follows:
  xlChart = -4109
  xlDialogSheet = -4116
  xlExcel4IntlMacroSheet = 4
  xlExcel4MacroSheet = 3
  xlWorksheet = -4167

Returns the number which represents variable kind.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'XlSheetType')
variables = tobj.variables
variables.each do |variable|
  puts "#{variable.name} #{variable.varkind}"
end

The result of above script is following:
   xlChart 2
   xlDialogSheet 2
   xlExcel4IntlMacroSheet 2
   xlExcel4MacroSheet 2
   xlWorksheet 2

Returns OLE variant type.

obj = WIN32OLE_VARIANT.new("string")
obj.vartype # => WIN32OLE::VARIANT::VT_BSTR

Creates a GzipReader or GzipWriter associated with io, passing in any necessary extra options, and executes the block with the newly created object just like File.open.

The GzipFile object will be closed automatically after executing the block. If you want to keep the associated IO object open, you may call Zlib::GzipFile#finish method in the block.

The line number of the last row read from this file.

Specify line number of the last row read from this file.

Resets the position of the file pointer to the point created the GzipReader object. The associated IO object needs to respond to the seek method.
