Returns true if the set and the given enumerable have at least one element in common.
Set[1, 2, 3].intersect? Set[4, 5] #=> false Set[1, 2, 3].intersect? Set[3, 4] #=> true Set[1, 2, 3].intersect? 4..5 #=> false Set[1, 2, 3].intersect? [3, 4] #=> true
Returns a string created by converting each element of the set to a string.
Deletes every element that appears in the given enumerable object and returns self.
Returns a new set containing elements common to the set and the given enumerable object.
Set[1, 3, 5] & Set[3, 2, 1] #=> #<Set: {3, 1}> Set['a', 'b', 'z'] & ['a', 'b', 'c'] #=> #<Set: {"a", "b"}>
Returns the number of elements.
Returns a string representation of self
:
Customer = Struct.new(:name, :address, :zip) # => Customer joe = Customer.new("Joe Smith", "123 Maple, Anytown NC", 12345) joe.inspect # => "#<struct Customer name=\"Joe Smith\", address=\"123 Maple, Anytown NC\", zip=12345>"
Returns the number of members.
Customer = Struct.new(:name, :address, :zip) joe = Customer.new("Joe Smith", "123 Maple, Anytown NC", 12345) joe.size #=> 3
Returns a string representation of self
(including the leading colon):
:foo.inspect # => ":foo"

Equivalent to self.to_s.length
; see String#length
.
Returns true
if self
points to a mountpoint.
Joins the given pathnames onto self
to create a new Pathname
object. This is effectively the same as using Pathname#+
to append self
and all arguments sequentially.
path0 = Pathname.new("/usr") # Pathname:/usr path0 = path0.join("bin/ruby") # Pathname:/usr/bin/ruby # is the same as path1 = Pathname.new("/usr") + "bin/ruby" # Pathname:/usr/bin/ruby path0 == path1 #=> true
Iterates over the directory tree in a depth first manner, yielding a Pathname
for each file under “this” directory.
Returns an Enumerator
if no block is given.
Since it is implemented by the standard library module Find
, Find.prune
can be used to control the traversal.
If self
is .
, yielded pathnames begin with a filename in the current directory, not ./
.
See Find.find
Recursively deletes a directory, including all directories beneath it.
See FileUtils.rm_rf
Returns all the bytes from the file, or the first N
if specified.
