Makes a list of existing constants public.
Makes a list of existing constants private.
Execute the provided block, but preserve the exception mode
BigDecimal.save_exception_mode do BigDecimal.mode(BigDecimal::EXCEPTION_OVERFLOW, false) BigDecimal.mode(BigDecimal::EXCEPTION_NaN, false) BigDecimal(BigDecimal('Infinity')) BigDecimal(BigDecimal('-Infinity')) BigDecimal(BigDecimal('NaN')) end
For use with the BigDecimal::EXCEPTION_*
See BigDecimal.mode
Returns reference counter of Dispatch interface of WIN32OLE
object. You should not use this method because this method exists only for debugging WIN32OLE
.
Breaks the buffer into lines that are shorter than maxwidth
Counts objects for each T_IMEMO
type.
This method is only for MRI developers interested in performance and memory usage of Ruby programs.
It returns a hash as:
{:imemo_ifunc=>8, :imemo_svar=>7, :imemo_cref=>509, :imemo_memo=>1, :imemo_throw_data=>1}
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 symbol objects.
This method is only expected to work with C Ruby.
Returns whether or not the struct of type type
contains member
. If it does not, or the struct type can’t be found, then false is returned. You may optionally specify additional headers
in which to look for the struct (in addition to the common header files).
If found, a macro is passed as a preprocessor constant to the compiler using the type name and the member name, in uppercase, prepended with HAVE_
.
For example, if have_struct_member('struct foo', 'bar')
returned true, then the HAVE_STRUCT_FOO_BAR
preprocessor macro would be passed to the compiler.
HAVE_ST_BAR
is also defined for backward compatibility.
Is this handler a streaming handler?
Returns the type library version.
tlib = WIN32OLE_TYPELIB.new('Microsoft Excel 9.0 Object Library') puts tlib.version #-> "1.3"
If the buffer is read only, meaning the buffer cannot be modified using set_value
, set_string
or copy
and similar.
Frozen strings and read-only files create read-only buffers.
Returns true
; retained for compatibility.
Sends an HTTPRequest
object req
to the HTTP
server.
If req
is a Net::HTTP::Post
or Net::HTTP::Put
request containing data, the data is also sent. Providing data for a Net::HTTP::Head
or Net::HTTP::Get
request results in an ArgumentError
.
Returns an HTTPResponse
object.
When called with a block, passes an HTTPResponse
object to the block. The body of the response will not have been read yet; the block can process it using HTTPResponse#read_body
, if desired.
This method never raises Net::* exceptions.
Returns error reason. Override this for I18N.
