I found following exp from html_parser.rb

n = Integer(name)

here, name is string


Is the Integer used as class method?
it looks like converting from str to int.
Where can I get this info?
I checked "the ruby way' and "programming ruby'
but i couldn't find any info about it.

thanks.

In fact it's Kernel.Integer(name) cf
http://www.rubycentral.com/book/ref_m_kernel.html#Kernel.Integer
Integer is a "method" of the Kernel module.

That's not the one he wants

batsman@tux-chan:~/src/rdocsite/site/ruby$ ri Kernel.Integer -------------------------------------------------------- Kernel::Integer
Integer( arg ) -> anInteger
------------------------------------------------------------------------
Converts arg to a Fixnum or Bignum. Numeric types are converted
directly (with floating point numbers being truncated). If arg is a
String, leading radix indicators (0, 0b, and 0x) are honored. This
behavior is different from that of String#to_i.
Integer(123.999) #=> 123
Integer("0x1a") #=> 26
Integer(Time.new) #=> 983770240

But don't forget that Integer( nil ) #=> 0
