Results for: "pstore"

Iterates the given block, passing in integer values from int up to and including limit.

If no block is given, an Enumerator is returned instead.

For example:

5.upto(10) { |i| print i, " " }
#=> 5 6 7 8 9 10

Iterates the given block, passing decreasing values from int down to and including limit.

If no block is given, an Enumerator is returned instead.

5.downto(1) { |n| print n, ".. " }
print "  Liftoff!\n"
#=> "5.. 4.. 3.. 2.. 1..   Liftoff!"

Returns the Integer equal to int - 1.

1.pred      #=> 0
(-1).pred   #=> -2

Returns the int itself.

?a.ord    #=> 97

This method is intended for compatibility to character constant in Ruby 1.9.

For example, ?a.ord returns 97 both in 1.8 and 1.9.

As int is already an Integer, all these methods simply return the receiver.

Synonyms is to_int

Converts int to a Float. If int doesn’t fit in a Float, the result is infinity.

Returns the largest number less than or equal to int in decimal digits (default 0 digits).

Precision may be negative. Returns a floating point number when ndigits is positive, self for zero, and floor down for negative.

1.floor        #=> 1
1.floor(2)     #=> 1.0
15.floor(-1)   #=> 10

Returns the remainder after dividing big by numeric as:

x.remainder(y) means x-y*(x/y).truncate

Examples

5.remainder(3)    #=> 2
-5.remainder(3)   #=> -2
5.remainder(-3)   #=> 2
-5.remainder(-3)  #=> -2

-1234567890987654321.remainder(13731)      #=> -6966
-1234567890987654321.remainder(13731.24)   #=> -9906.22531493148

See Numeric#divmod.

Returns the value as a rational.

1.to_r        #=> (1/1)
(1<<64).to_r  #=> (18446744073709551616/1)

Looks up the first IP address for name.

Looks up all IP address for name.

The content of the TempIO as a String.

Replaces the contents of the set with the contents of the given enumerable object and returns self.

Converts the set to an array. The order of elements is uncertain.

Equivalent to Set#delete_if, but returns nil if no changes were made. Returns an enumerator if no block is given.

Creates a temporary file as usual File object (not Tempfile). It doesn’t use finalizer and delegation.

If no block is given, this is similar to Tempfile.new except creating File instead of Tempfile. The created file is not removed automatically. You should use File.unlink to remove it.

If a block is given, then a File object will be constructed, and the block is invoked with the object as the argument. The File object will be automatically closed and the temporary file is removed after the block terminates. The call returns the value of the block.

In any case, all arguments (+*args+) will be treated as Tempfile.new.

Tempfile.create('foo', '/home/temp') do |f|
   ... do something with f ...
end

The string representation of true is “true”.

Basically the same as ::new. However, if class Thread is subclassed, then calling start in that subclass will not invoke the subclass’s initialize method.

Returns the currently executing thread.

Thread.current   #=> #<Thread:0x401bdf4c run>

Returns an array of Thread objects for all threads that are either runnable or stopped.

Thread.new { sleep(200) }
Thread.new { 1000000.times {|i| i*i } }
Thread.new { Thread.stop }
Thread.list.each {|t| p t}

This will produce:

#<Thread:0x401b3e84 sleep>
#<Thread:0x401b3f38 run>
#<Thread:0x401b3fb0 sleep>
#<Thread:0x401bdf4c run>
