Similar to instance_method, searches public method only.

Returns a string representation of lex_state.

Returns true for IPv6 unique local address (fc00::/7, RFC4193). It returns false otherwise.

Returns true for IPv6 multicast node-local scope address. It returns false otherwise.

Returns true for IPv6 multicast link-local scope address. It returns false otherwise.

Returns true for IPv6 multicast site-local scope address. It returns false otherwise.

Returns true for IPv6 multicast organization-local scope address. It returns false otherwise.

Returns true for IPv6 multicast global scope address. It returns false otherwise.

Initialize WIN32OLE object(ActiveX Control) by calling IPersistMemory::InitNew.

Before calling OLE method, some kind of the ActiveX controls created with MFC should be initialized by calling IPersistXXX::InitNew.

If and only if you received the exception “HRESULT error code: 0x8000ffff catastrophic failure”, try this method before invoking any ole_method.

obj = WIN32OLE.new("ProgID_or_GUID_of_ActiveX_Control")
obj.ole_activex_initialize
obj.method(...)

Handle BasicObject instances

Returns the value of the local variable symbol.

def foo
  a = 1
  binding.local_variable_get(:a) #=> 1
  binding.local_variable_get(:b) #=> NameError
end

This method is the short version of the following code:

binding.eval("#{symbol}")

Set local variable named symbol as obj.

def foo
  a = 1
  bind = binding
  bind.local_variable_set(:a, 2) # set existing local variable `a'
  bind.local_variable_set(:b, 3) # create new local variable `b'
                                 # `b' exists only in binding

  p bind.local_variable_get(:a)  #=> 2
  p bind.local_variable_get(:b)  #=> 3
  p a                            #=> 2
  p b                            #=> NameError
end

This method behaves similarly to the following code:

binding.eval("#{symbol} = #{obj}")

if obj can be dumped in Ruby code.

Returns true if a local variable symbol exists.

def foo
  a = 1
  binding.local_variable_defined?(:a) #=> true
  binding.local_variable_defined?(:b) #=> false
end

This method is the short version of the following code:

binding.eval("defined?(#{symbol}) == 'local-variable'")

Counts objects for each T_DATA type.

This method is only for MRI developers interested in performance and memory usage of Ruby programs.

It returns a hash as:

{RubyVM::InstructionSequence=>504, :parser=>5, :barrier=>6,
 :mutex=>6, Proc=>60, RubyVM::Env=>57, Mutex=>1, Encoding=>99,
 ThreadGroup=>1, Binding=>1, Thread=>1, RubyVM=>1, :iseq=>1,
 Random=>1, ARGF.class=>1, Data=>1, :autoload=>3, Time=>2}
# T_DATA objects existing at startup on r32276.

If the optional argument, result_hash, is given, it is overwritten and returned. This is intended to avoid probe effect.

The contents of the returned hash is implementation specific and may change in the future.

In this version, keys are Class object or Symbol object.

If object is kind of normal (accessible) object, the key is Class object. If object is not a kind of normal (internal) object, the key is symbol name, registered by rb_data_type_struct.

This method is only expected to work with C Ruby.

MRI specific feature

Return internal class of obj.

obj can be an instance of InternalObjectWrapper.

Note that you should not use this method in your application.

MRI specific feature

Return internal super class of cls (Class or Module).

obj can be an instance of InternalObjectWrapper.

Note that you should not use this method in your application.

Calls CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON). Starts tracking memory allocations. See also OpenSSL.print_mem_leaks.

This is available only when built with a capable OpenSSL and –enable-debug configure option.

Verify internal consistency.

This method is implementation specific. Now this method checks generational consistency if RGenGC is supported.
