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 true if the set and the given enumerable have no element in common. This method is the opposite of intersect?.
Set[1, 2, 3].disjoint? Set[3, 4] #=> false Set[1, 2, 3].disjoint? Set[4, 5] #=> true Set[1, 2, 3].disjoint? [3, 4] #=> false Set[1, 2, 3].disjoint? 4..5 #=> true
Deletes every element that appears in the given enumerable object and returns self.
Returns a string created by converting each element of the set to a string See also: Array#join
Returns a string containing a human-readable representation of the set (“#<Set: {element1, element2, …}>”).
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.
See File.binread.
See File.lstat.
