Detailed Description

template<typename CharT, typename ByteT>
class Pt::BasicTextIStream< CharT, ByteT >

This stream decodes an external character sequence using a codec. Reading from the stream will convert from the the encoding of external characters.

Constructor & Destructor Documentation

◆ BasicTextIStream() [1/2]

BasicTextIStream	(	StreamType &	is,
		CodecType *	codec
	)

The input stream is is used to read a character sequence and convert it using the codec codec. The codec object which is passed as pointer will be managed by this class and deleted if its reference count reaches 0.

◆ BasicTextIStream() [2/2]

BasicTextIStream ( CodecType * codec )

explicit

The codec object which is passed as pointer will be managed by this class and deleted if its reference count reaches 0.

Member Function Documentation

◆ setCodec()

void setCodec ( CodecType * codec )

The codec object which is passed as pointer will be managed by this class and deleted if its reference count reaches 0.

◆ reset() [1/2]

void reset ( )

The target is detached and the buffer content is discarded. The codec is kept, if one was set previously.

◆ reset() [2/2]

void reset ( StreamType & is )

Attaches to the new target and discards the buffer. The codec is kept, if one was set previously.

◆ peeksome()

std::streamsize peeksome	(	CharT *	buffer,
		std::streamsize	n
	)

inherited

The number of bytes that can be peeked depends on the current stream buffer get area and maybe less than requested, similar to istream::readsome().
