Detailed Description

template<class CHARTYPE, class INPUTITERATOR = bsl::istreambuf_iterator<CHARTYPE>>
class bdldfp::DecimalNumGet< CHARTYPE, INPUTITERATOR >

A facet type (mechanism) used in reading decimal floating-point types. Note that this type does not follow BDE conventions because its content is dictated by the C++ standard and native standard library implementations. See ISO/IEC TR 24733 3.10.2 for details.

See Component bdldfp_decimal

Constructor & Destructor Documentation

template<class CHARTYPE, class INPUTITERATOR = bsl::istreambuf_iterator<CHARTYPE>>

bdldfp::DecimalNumGet< CHARTYPE, INPUTITERATOR >::DecimalNumGet ( bsl::size_t refs = 0 ) [explicit]

Constructs a DecimalNumGet object. Optionally specify starting reference count refs, which will default to 0. If refs is non-zero, the DecimalNumGet object will not be deleted when the last locale referencing it goes out of scope.

template<class CHARTYPE, class INPUTITERATOR = bsl::istreambuf_iterator<CHARTYPE>>

bdldfp::DecimalNumGet< CHARTYPE, INPUTITERATOR >::~DecimalNumGet ( ) [protected]

Destroy this object. Note that the destructor is virtual.

Interpret characters from the half-open iterator range denoted by the specified begin and end, generate a decimal floating-point number and store it into the specified value. During conversion the formatting flags of the specified str (str.flags()) are obeyed; character classifications are determined by the bsl::ctype while punctuation characters are determined by the bsl::numpunct facet imbued to the str stream-base. Use the specified err to report back failure or EOF streams states. For further, more detailed information please consult the section [lib.facet.num.get.virtuals] of the C++ Standard. Note that for the conversions to the Decimal32, 64 and 128 types the conversion specifiers are Hg, Dg and DDg, respectively. Also note that these (possibly overridden) do_get virtual function are used by every formatted C++ stream input operator call (in >> aDecNumber).
