Returns detail information of type. The information is array of type.
tobj = WIN32OLE_TYPE.new('DirectX 7 for Visual Basic Type Library', 'D3DCLIPSTATUS') variable = tobj.variables.find {|variable| variable.name == 'lFlags'} tdetail = variable.ole_type_detail p tdetail # => ["USERDEFINED", "CONST_D3DCLIPSTATUSFLAGS"]

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.
Return internal class of obj.
obj can be an instance of InternalObjectWrapper
.
Note that you should not use this method in your application.
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.
Shortcut for defining multiple delegator methods, but with no provision for using a different name. The following two code samples have the same effect:
def_delegators :@records, :size, :<<, :map def_delegator :@records, :size def_delegator :@records, :<< def_delegator :@records, :map
Define method
as delegator instance method with an optional alias name ali
. Method
calls to ali
will be delegated to accessor.method
. accessor
should be a method name, instance variable name, or constant name. Use the full path to the constant if providing the constant name. Returns the name of the method defined.
class MyQueue CONST = 1 extend Forwardable attr_reader :queue def initialize @queue = [] end def_delegator :@queue, :push, :mypush def_delegator 'MyQueue::CONST', :to_i end q = MyQueue.new q.mypush 42 q.queue #=> [42] q.push 23 #=> NoMethodError q.to_i #=> 1
Returns strongly connected components as an array of arrays of nodes. The array is sorted from children to parents. Each elements of the array represents a strongly connected component.
class G include TSort def initialize(g) @g = g end def tsort_each_child(n, &b) @g[n].each(&b) end def tsort_each_node(&b) @g.each_key(&b) end end graph = G.new({1=>[2, 3], 2=>[4], 3=>[2, 4], 4=>[]}) p graph.strongly_connected_components #=> [[4], [2], [3], [1]] graph = G.new({1=>[2], 2=>[3, 4], 3=>[2], 4=>[]}) p graph.strongly_connected_components #=> [[4], [2, 3], [1]]
Returns strongly connected components as an array of arrays of nodes. The array is sorted from children to parents. Each elements of the array represents a strongly connected component.
The graph is represented by each_node and each_child. each_node should have call
method which yields for each node in the graph. each_child should have call
method which takes a node argument and yields for each child node.
