Returns the array of WIN32OLE_TYPE object which is implemented by the WIN32OLE_TYPE object.
tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Worksheet') p tobj.implemented_ole_types # => [_Worksheet, DocEvents]
Returns the array of WIN32OLE_TYPE object which is implemented by the WIN32OLE_TYPE object and having IMPLTYPEFLAG_FSOURCE and IMPLTYPEFLAG_FDEFAULT.
tobj = WIN32OLE_TYPE.new('Microsoft Internet Controls', "InternetExplorer") p tobj.default_event_sources # => [#<WIN32OLE_TYPE:DWebBrowserEvents2>]
The block passed to this method will be called just before running the RDoc generator. It is allowed to modify RDoc::Task attributes inside the block.
Returns the value of a thread local variable that has been set. Note that these are different than fiber local values. For fiber local values, please see Thread#[] and Thread#[]=.
Thread local values are carried along with threads, and do not respect fibers. For example:
Thread.new { Thread.current.thread_variable_set("foo", "bar") # set a thread local Thread.current["foo"] = "bar" # set a fiber local Fiber.new { Fiber.yield [ Thread.current.thread_variable_get("foo"), # get the thread local Thread.current["foo"], # get the fiber local ] }.resume }.join.value # => ['bar', nil]
The value “bar” is returned for the thread local, where nil is returned for the fiber local. The fiber is executed in the same thread, so the thread local values are available.
Sets a thread local with key to value. Note that these are local to threads, and not to fibers. Please see Thread#thread_variable_get and Thread#[] for more information.
Return consuming memory size of all living objects.
If klass (should be Class object) is given, return the total memory size of instances of the given class.
Note that the returned size is incomplete. You need to deal with this information as only a HINT. Especially, the size of T_DATA may not be correct.
Note that this method does NOT return total malloc’ed memory size.
This method can be defined by the following Ruby code:
def memsize_of_all klass = false total = 0 ObjectSpace.each_object{|e| total += ObjectSpace.memsize_of(e) if klass == false || e.kind_of?(klass) } total end
This method is only expected to work with C Ruby.
Return all reachable objects from ‘obj’.
This method returns all reachable objects from ‘obj’.
If ‘obj’ has two or more references to the same object ‘x’, then returned array only includes one ‘x’ object.
If ‘obj’ is a non-markable (non-heap management) object such as true, false, nil, symbols and Fixnums (and Flonum) then it simply returns nil.
If ‘obj’ has references to an internal object, then it returns instances of ObjectSpace::InternalObjectWrapper class. This object contains a reference to an internal object and you can check the type of internal object with ‘type’ method.
If ‘obj’ is instance of ObjectSpace::InternalObjectWrapper class, then this method returns all reachable object from an internal object, which is pointed by ‘obj’.
With this method, you can find memory leaks.
This method is only expected to work except with C Ruby.
Example:
ObjectSpace.reachable_objects_from(['a', 'b', 'c']) #=> [Array, 'a', 'b', 'c'] ObjectSpace.reachable_objects_from(['a', 'a', 'a']) #=> [Array, 'a', 'a', 'a'] # all 'a' strings have different object id ObjectSpace.reachable_objects_from([v = 'a', v, v]) #=> [Array, 'a'] ObjectSpace.reachable_objects_from(1) #=> nil # 1 is not markable (heap managed) object
For debugging the Ruby/OpenSSL library. Calls CRYPTO_mem_leaks_fp(stderr). Prints detected memory leaks to standard error. This cleans the global state up thus you cannot use any methods of the library after calling this.
Returns true if leaks detected, false otherwise.
This is available only when built with a capable OpenSSL and –enable-debug configure option.
OpenSSL.mem_check_start NOT_GCED = OpenSSL::PKey::RSA.new(256) END { GC.start OpenSSL.print_mem_leaks # will print the leakage }
Set terminal size to rows and columns.
See GNU Readline’s rl_set_screen_size function.
Raises NotImplementedError if the using readline library does not support.
Returns the terminal’s rows and columns.
See GNU Readline’s rl_get_screen_size function.
Raises NotImplementedError if the using readline library does not support.
Specifies VI editing mode. See the manual of GNU Readline for details of VI editing mode.
Raises NotImplementedError if the using readline library does not support.
Returns true if vi mode is active. Returns false if not.
Raises NotImplementedError if the using readline library does not support.
Specifies a Proc object proc to call after the first prompt has been printed and just before readline starts reading input characters.
See GNU Readline’s rl_pre_input_hook variable.
Raises ArgumentError if proc does not respond to the call method.
Raises NotImplementedError if the using readline library does not support.
Returns a Proc object proc to call after the first prompt has been printed and just before readline starts reading input characters. The default is nil.
Raises NotImplementedError if the using readline library does not support.

Returns a duplicate table object, in mixed mode. This is handy for chaining in a single call without changing the table mode, but be aware that this method can consume a fair amount of memory for bigger data sets.
This method returns the duplicate table for chaining. Don’t chain destructive methods (like []=()) this way though, since you are working with a duplicate.
Switches the mode of this table to mixed mode. All calls to indexing and iteration methods will use the default intelligent indexing system until the mode is changed again. In mixed mode an index is assumed to be a row reference while anything else is assumed to be column access by headers.
This method returns the table and is safe to chain.
