Returns the size of arguments of the method.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbook')
method = WIN32OLE_METHOD.new(tobj, 'SaveAs')
puts method.size_params # => 11

Returns major version.

tobj = WIN32OLE_TYPE.new('Microsoft Word 10.0 Object Library', 'Documents')
puts tobj.major_version # => 8

Returns minor version.

tobj = WIN32OLE_TYPE.new('Microsoft Word 10.0 Object Library', 'Documents')
puts tobj.minor_version # => 2

Returns the type library major version.

tlib = WIN32OLE_TYPELIB.new('Microsoft Excel 9.0 Object Library')
puts tlib.major_version # -> 1

Returns the type library minor version.

tlib = WIN32OLE_TYPELIB.new('Microsoft Excel 9.0 Object Library')
puts tlib.minor_version # -> 3

Try to convert obj into a hash, using to_hash method. Returns converted hash or nil if obj cannot be converted for any reason.

Hash.try_convert({1=>2})   # => {1=>2}
Hash.try_convert("1=>2")   # => nil

This method is a shortcut for converting a single line of a CSV String into an Array. Note that if line contains multiple rows, anything beyond the first row is ignored.

The options parameter can be anything CSV::new() understands.

Returns true if unconverted_fields() to parsed results. See CSV::new for details.

Returns the current list of converters in effect for headers. See CSV::new for details. Built-in converters will be returned by name, while others will be returned as is.

Returns true if illegal input is handled. See CSV::new for details.

Identical to CSV#convert(), but for header rows.

Note that this method must be called before header rows are read to have any effect.

No documentation available

Processes fields with @converters, or @header_converters if headers is passed as true, returning the converted field set. Any converter that changes the field into something other than a String halts the pipeline of conversion for that field. This is primarily an efficiency shortcut.

No documentation available

Returns a string for DNS reverse lookup compatible with RFC3172.

Set date-time format.

datetime_format

A string suitable for passing to strftime.

Returns the date format being used. See datetime_format=

Returns the factorization of value.

Parameters

value

An arbitrary integer.

generator

Optional. A pseudo-prime generator. generator.succ must return the next pseudo-prime number in the ascending order. It must generate all prime numbers, but may also generate non prime numbers too.

Exceptions

ZeroDivisionError

when value is zero.

Example

For an arbitrary integer:

n = p_1**e_1 * p_2**e_2 * .... * p_n**e_n,

prime_division(n) returns:

[[p_1, e_1], [p_2, e_2], ...., [p_n, e_n]].

Prime.prime_division(12) #=> [[2,2], [3,1]]

Ruby tries to load the library named string relative to the requiring file’s path. If the file’s path cannot be determined a LoadError is raised. If a file is loaded true is returned and false otherwise.

Leaves exclusive section.

Enters exclusive section and executes the block. Leaves the exclusive section automatically when the block exits. See example under MonitorMixin.

Parse a file at filename. Returns the Psych::Nodes::Document.

Raises a Psych::SyntaxError when a YAML syntax error is detected.

Parse a YAML string in yaml. Returns the Psych::Nodes::Stream. This method can handle multiple YAML documents contained in yaml. filename is used in the exception message if a Psych::SyntaxError is raised.

If a block is given, a Psych::Nodes::Document node will be yielded to the block as it’s being parsed.

Raises a Psych::SyntaxError when a YAML syntax error is detected.

Example:

Psych.parse_stream("---\n - a\n - b") # => #<Psych::Nodes::Stream:0x00>

Psych.parse_stream("--- a\n--- b") do |node|
  node # => #<Psych::Nodes::Document:0x00>
end

begin
  Psych.parse_stream("--- `", filename: "file.txt")
rescue Psych::SyntaxError => ex
  ex.file    # => 'file.txt'
  ex.message # => "(file.txt): found character that cannot start any token"
end

Raises a TypeError when NilClass is passed.

See Psych::Nodes for more information about YAML AST.
