sets event handler object. If handler object has onXXX method according to XXX event, then onXXX method is called when XXX event occurs.
If handler object has method_missing and there is no method according to the event, then method_missing called and 1-st argument is event name.
If handler object has onXXX method and there is block defined by WIN32OLE_EVENT#on_event(‘XXX’){}, then block is executed but handler object method is not called when XXX event occurs.
class Handler def onStatusTextChange(text) puts "StatusTextChanged" end def onPropertyChange(prop) puts "PropertyChanged" end def method_missing(ev, *arg) puts "other event #{ev}" end end handler = Handler.new ie = WIN32OLE.new('InternetExplorer.Application') ev = WIN32OLE_EVENT.new(ie) ev.on_event("StatusTextChange") {|*args| puts "this block executed." puts "handler.onStatusTextChange method is not called." } ev.handler = handler
returns handler object.
Returns true if the method is public.

Returns true if the type library information is not hidden. If wLibFlags of TLIBATTR is 0 or LIBFLAG_FRESTRICTED or LIBFLAG_FHIDDEN, the method returns false, otherwise, returns true. If the method fails to access the TLIBATTR information, then WIN32OLERuntimeError
is raised.

Returns the adler-32 checksum.
Returns compression level.
Returns true
if stat is readable by the effective user id of this process.
File.stat("testfile").readable? #=> true
Returns true
if stat is writable by the effective user id of this process.
File.stat("testfile").writable? #=> true
Returns true
if stat is executable or if the operating system doesn’t distinguish executable files from nonexecutable files. The tests are made using the effective owner of the process.
File.stat("testfile").executable? #=> false
Returns true
if stat is a regular file (not a device file, pipe, socket, etc.).
File.stat("testfile").file? #=> true
Returns the number of referenced objects
If the buffer was freed with free

Fill buffer with value

bytes.

Returns the instruction sequence as a String
in human readable form.

Takes source
, a String
of Ruby code and compiles it to an InstructionSequence
.
Optionally takes file
, path
, and line
which describe the file path, real path and first line number of the ruby code in source
which are metadata attached to the returned iseq
.
file
is used for ‘__FILE__` and exception backtrace. path
is used for require_relative
base. It is recommended these should be the same full path.
options
, which can be true
, false
or a Hash
, is used to modify the default behavior of the Ruby iseq compiler.
For details regarding valid compile options see ::compile_option=
.

Takes body
, a Method
or Proc
object, and returns a String
with the human readable instructions for body
.
For a Method
object:
# /tmp/method.rb def hello puts "hello, world" end puts RubyVM::InstructionSequence.disasm(method(:hello))
Produces:
== disasm: <RubyVM::InstructionSequence:hello@/tmp/method.rb>============ 0000 trace 8 ( 1) 0002 trace 1 ( 2) 0004 putself 0005 putstring "hello, world" 0007 send :puts, 1, nil, 8, <ic:0> 0013 trace 16 ( 3) 0015 leave ( 2)
For a Proc:
# /tmp/proc.rb p = proc { num = 1 + 2 } puts RubyVM::InstructionSequence.disasm(p)
Produces:
