Return the receiver associated with this KeyError exception.

Return the receiver associated with this NameError exception.

Return the receiver associated with this FrozenError exception.

Returns an array of Refinement defined within the receiver.

p A.refinements

produces:

[#<refinement:Integer@A>, #<refinement:String@A>]

Returns true if range overlaps with self, false otherwise:

(0..2).overlap?(1..3) #=> true
(0..2).overlap?(3..4) #=> false
(0..).overlap?(..0)   #=> true

With non-range argument, raises TypeError.

(1..3).overlap?(1)         # TypeError

Returns false if an internal call to <=> returns nil; that is, the operands are not comparable.

(1..3).overlap?('a'..'d')  # => false

Returns false if self or range is empty. “Empty range” means that its begin value is larger than, or equal for an exclusive range, its end value.

(4..1).overlap?(2..3)      # => false
(4..1).overlap?(..3)       # => false
(4..1).overlap?(2..)       # => false
(2...2).overlap?(1..2)     # => false

(1..4).overlap?(3..2)      # => false
(..4).overlap?(3..2)       # => false
(1..).overlap?(3..2)       # => false
(1..2).overlap?(2...2)     # => false

Returns false if the begin value one of self and range is larger than, or equal if the other is an exclusive range, the end value of the other:

(4..5).overlap?(2..3)      # => false
(4..5).overlap?(2...4)     # => false

(1..2).overlap?(3..4)      # => false
(1...3).overlap?(3..4)     # => false

Returns false if the end value one of self and range is larger than, or equal for an exclusive range, the end value of the other:

(4..5).overlap?(2..3)      # => false
(4..5).overlap?(2...4)     # => false

(1..2).overlap?(3..4)      # => false
(1...3).overlap?(3..4)     # => false

Note that the method wouldn’t make any assumptions about the beginless range being actually empty, even if its upper bound is the minimum possible value of its type, so all this would return true:

(...-Float::INFINITY).overlap?(...-Float::INFINITY) # => true
(..."").overlap?(..."") # => true
(...[]).overlap?(...[]) # => true

Even if those ranges are effectively empty (no number can be smaller than -Float::INFINITY), they are still considered overlapping with themselves.

The opposite of Pathname#absolute?

It returns false if the pathname begins with a slash.

p = Pathname.new('/im/sure')
p.relative?
    #=> false

p = Pathname.new('not/so/sure')
p.relative?
    #=> true

Returns a string for DNS reverse lookup. It returns a string in RFC3172 form for an IPv6 address.

Returns the bound receiver of the binding object.

Returns the bound receiver of the method object.

(1..3).method(:map).receiver # => 1..3

Receive a message from the incoming port of the current ractor (which was sent there by send from another ractor).

r = Ractor.new do
  v1 = Ractor.receive
  puts "Received: #{v1}"
end
r.send('message1')
r.take
# Here will be printed: "Received: message1"

Alternatively, the private instance method receive may be used:

r = Ractor.new do
  v1 = receive
  puts "Received: #{v1}"
end
r.send('message1')
r.take
# This prints: "Received: message1"

The method blocks if the queue is empty.

r = Ractor.new do
  puts "Before first receive"
  v1 = Ractor.receive
  puts "Received: #{v1}"
  v2 = Ractor.receive
  puts "Received: #{v2}"
end
wait
puts "Still not received"
r.send('message1')
wait
puts "Still received only one"
r.send('message2')
r.take

Output:

Before first receive
Still not received
Received: message1
Still received only one
Received: message2

If close_incoming was called on the ractor, the method raises Ractor::ClosedError if there are no more messages in the incoming queue:

Ractor.new do
  close_incoming
  receive
end
wait
# in `receive': The incoming port is already closed => #<Ractor:#2 test.rb:1 running> (Ractor::ClosedError)

same as Ractor.receive

When RubyGems is required, Kernel#require is replaced with our own which is capable of loading gems on demand.

When you call require 'x', this is what happens:

• If the file can be loaded from the existing Ruby loadpath, it is.

• Otherwise, installed gems are searched for a file that matches. If it’s found in gem ‘y’, that gem is activated (added to the loadpath).

The normal require functionality of returning false if that file has already been loaded is preserved.

Refresh available gems from disk.
