basic_stringbuf 클래스

아티클
06/09/2015

Describes a stream buffer that controls the transmission of elements of type Elem, whose character traits are determined by the class Tr, to and from a sequence of elements stored in an array object.

template <class Elem, class Tr = char_traits<Elem>, 
   class Alloc = allocator<Elem> 
>
   class basic_stringbuf : public basic_streambuf<Elem, Tr>

매개 변수

Alloc
The allocator class.
Elem
The type of the basic element of the string.
Tr
The character traits specialized on the basic element of the string.

설명

The object is allocated, extended, and freed as necessary to accommodate changes in the sequence.

An object of class basic_stringbuf<Elem, Tr, Alloc> stores a copy of the ios_base::openmode argument from its constructor as its stringbuf mode mode:

If mode & ios_base::in is nonzero, the input buffer is accessible. 자세한 내용은 basic_streambuf 클래스을 참조하십시오.
If mode & ios_base::out is nonzero, the output buffer is accessible.

'basic_stringbuf' 형식의 개체를 생성합니다.

형식 정의

allocator_type	The type is a synonym for the template parameter Alloc.
char_type	Associates a type name with the Elem template parameter.
int_type	Makes this type within basic_filebuf's scope equivalent to the type of the same name in the Tr scope.
off_type	Makes this type within basic_filebuf's scope equivalent to the type of the same name in the Tr scope.
pos_type	Makes this type within basic_filebuf's scope equivalent to the type of the same name in the Tr scope.
특성 형식	Associates a type name with the Tr template parameter.

멤버 함수

오버플로(overflow)	A protected, virtual function that can be called when a new character is inserted into a full buffer.
pbackfail	The protected virtual member function tries to put back an element into the input buffer, then makes it the current element (pointed to by the next pointer).
seekoff	The protected virtual member function tries to alter the current positions for the controlled streams.
seekpos	The protected virtual member function tries to alter the current positions for the controlled streams.
str	Sets or gets the text in a string buffer without changing the write position.
underflow	The protected virtual member function to extract the current element from the input stream.
