Standard input stream backed by a bsl::basic_string character sequence.

Synopsis

Declared in <bslstl_istringstream.h>

template<
    class CHAR_TYPE,
    class CHAR_TRAITS = char_traits<CHAR_TYPE>,
    class ALLOCATOR = allocator<CHAR_TYPE>>
class basic_istringstream
    : public std::basic_istream<CHAR_TYPE, CHAR_TRAITS>

Description

This class implements a standard input stream that provides a constructor and manipulator for setting the sequence of characters from which input is streamed to a supplied bsl::basic_string.

tellg

Getting the current read position.

unget

Unextracting the previous character.

view

Return a view of the internally buffered sequence of characters maintained by this stream object.

Using Declarations

Name

Description

gcount

Return the number of characters extracted by the last unformatted input.

ignore

Discard characters from the stream (inherited).

operator=

Assign from a base basic_istream (inherited).

peek

Return the next character without extracting it (inherited).

putback

Push a character back onto the input sequence (inherited).

read

Extract a block of characters into a buffer (inherited).

readsome

Extract available characters into a buffer (inherited).

sentry

Prefixed input operations sentry type inherited from basic_istream.

swap

Exchange this stream with another basic_istream (inherited).

sync

Synchronize the stream buffer with the underlying sequence (inherited).

tellg

Return the current get position in the input sequence (inherited).

unget
