Bind umeth to recv and then invokes the method with the specified arguments. This is semantically equivalent to umeth.bind(recv).call(args, ...).

Return the called name of the method being called

Returns the current execution stack—an array containing backtrace location objects.

See Thread::Backtrace::Location for more information.

The optional start parameter determines the number of initial stack entries to omit from the top of the stack.

A second optional length parameter can be used to limit how many entries are returned from the stack.

Returns nil if start is greater than the size of current execution stack.

Optionally you can pass a range, which will return an array containing the entries within the specified range.

Returns an array containing all elements of enum for which the given block returns a true value.

The find_all and select methods are aliases. There is no performance benefit to either.

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

(1..10).find_all { |i|  i % 3 == 0 }   #=> [3, 6, 9]

[1,2,3,4,5].select { |num|  num.even?  }   #=> [2, 4]

[:foo, :bar].filter { |x| x == :foo }   #=> [:foo]

Dump the contents of the ruby heap as JSON.

since must be a non-negative integer or nil.

If since is a positive integer, only objects of that generation and newer generations are dumped. The current generation can be accessed using GC::count.

Objects that were allocated without object allocation tracing enabled are ignored. See ::trace_object_allocations for more information and examples.

If since is omitted or is nil, all objects are dumped.

This method is only expected to work with C Ruby. This is an experimental method and is subject to change. In particular, the function signature and output format are not guaranteed to be compatible in future versions of ruby.

Returns the source file origin from the given object.

See ::trace_object_allocations for more information and examples.

Returns the original line from source for from the given object.

See ::trace_object_allocations for more information and examples.

Returns garbage collector generation for the given object.

class B
  include ObjectSpace

  def foo
    trace_object_allocations do
      obj = Object.new
      p "Generation is #{allocation_generation(obj)}"
    end
  end
end

B.new.foo #=> "Generation is 3"

Returns true if the named file is writable by the real user and group id of this process. See access(3).

Note that some OS-level security features may cause this to return true even though the file is not writable by the real user/group.

Returns true if the named file is executable by the real user and group id of this process. See access(3).

Windows does not support execute permissions separately from read permissions. On Windows, a file is only considered executable if it ends in .bat, .cmd, .com, or .exe.

Note that some OS-level security features may cause this to return true even though the file is not executable by the real user/group.

True if the gems in the system satisfy dependency.

Performs various checks before installing the gem such as the install repository is writable and its directories exist, required Ruby and rubygems versions are met and that dependencies are installed.

Version and dependency checks are skipped if this install is forced.

The dependent check will be skipped if the install is ignoring dependencies.

Installs from the gem dependencies files in the :gemdeps option in options, yielding to the block as in install.

If :without_groups is given in the options, those groups in the gem dependencies file are not used. See Gem::Installer for other options.

Looks up the latest specification for dependency and adds it to the always_install list.
