Detailed Description

template<typename _CharT, typename _InIter>
class std::num_get< _CharT, _InIter >

Primary class template num_get.

This facet encapsulates the code to parse and return a number from a string. It is used by the istream numeric extraction operators.

The num_get template uses protected virtual functions to provide the actual results. The public accessors forward the call to the virtual functions. These virtual functions are hooks for developers to implement the behavior they require from the num_get facet.

		bool &	__v
	)		const

inline

Numeric parsing.

Parses the input stream into the bool v. It does so by calling num_get::do_get().

If ios_base::boolalpha is set, attempts to read ctype<CharT>::truename() or ctype<CharT>::falsename(). Sets v to true or false if successful. Sets err to ios_base::failbit if reading the string fails. Sets err to ios_base::eofbit if the stream is emptied.

If ios_base::boolalpha is not set, proceeds as with reading a long, except if the value is 1, sets v to true, if the value is 0, sets v to false, and otherwise set err to ios_base::failbit.

Parameters

__in	Start of input stream.
__end	End of input stream.
__io	Source of locale and flags.
__err	Error flags to set.
__v	Value to format and insert.

Returns: Iterator after reading.

inline

Numeric parsing.

Parses the input stream into the integral variable v. It does so by calling num_get::do_get().

Parsing is affected by the flag settings in io.

The basic parse is affected by the value of io.flags() & ios_base::basefield. If equal to ios_base::oct, parses like the scanf o specifier. Else if equal to ios_base::hex, parses like X specifier. Else if basefield equal to 0, parses like the i specifier. Otherwise, parses like d for signed and u for unsigned types. The matching type length modifier is also used.

Digit grouping is interpreted according to numpunct::grouping() and numpunct::thousands_sep(). If the pattern of digit groups isn't consistent, sets err to ios_base::failbit.

If parsing the string yields a valid value for v, v is set. Otherwise, sets err to ios_base::failbit and leaves v unaltered. Sets err to ios_base::eofbit if the stream is emptied.

Parameters

__in	Start of input stream.
__end	End of input stream.
__io	Source of locale and flags.
__err	Error flags to set.
__v	Value to format and insert.

Returns: Iterator after reading.

Numeric parsing.

Parses the input stream into the pointer variable v. It does so by calling num_get::do_get().

The input characters are parsed like the scanf p specifier.

Digit grouping is interpreted according to numpunct::grouping() and numpunct::thousands_sep(). If the pattern of digit groups isn't consistent, sets err to ios_base::failbit.

Note that the digit grouping effect for pointers is a bit ambiguous in the standard and shouldn't be relied on. See DR 344.

If parsing the string yields a valid value for v, v is set. Otherwise, sets err to ios_base::failbit and leaves v unaltered. Sets err to ios_base::eofbit if the stream is emptied.

Parameters

__in	Start of input stream.
__end	End of input stream.
__io	Source of locale and flags.
__err	Error flags to set.
__v	Value to format and insert.

Returns: Iterator after reading.
