RWTPortalStreambuf is a streambuf that uses an RWPortal as its source and sink of bytes.

Member Typedef Documentation

template<class charT , class traits >

typedef charT RWTPortalStreambuf< charT, traits >::char_type

A typedef for the character type used by this stream buffer. This is an alias for the charT template parameter.

template<class charT , class traits >

typedef traits_type::int_type RWTPortalStreambuf< charT, traits >::int_type

A typedef for an integer type that is able to store all possible values of type char_type, including end-of-file.

template<class charT , class traits >

typedef traits RWTPortalStreambuf< charT, traits >::traits_type

A typedef for the character traits used by this stream buffer. This is an alias for the traits template parameter.

Constructor & Destructor Documentation

template<class charT , class traits >

RWTPortalStreambuf< charT, traits >::RWTPortalStreambuf

(

void

)

Constructs a streambuf without a source or sink of bytes. You need to set the source and sink using setPortal() before using self.

template<class charT , class traits >

RWTPortalStreambuf< charT, traits >::RWTPortalStreambuf

(

const RWPortal &

portal

)

Constructs a streambuf connected to the portal portal.

Member Function Documentation

template<class charT , class traits >

virtual int_type RWTPortalStreambuf< charT, traits >::overflow ( int_type  = traits_type::eof() )

protectedvirtual

Writes to the portal when the buffer overflows.

template<class charT , class traits >

void RWTPortalStreambuf< charT, traits >::setPortal	(	const RWPortal &	portal,
		bool	force = false
	)

Sets the communications channel into which you are writing. If force is true, the underlying portal is reassigned, and any exceptions thrown by the assignment are caught and ignored.

template<class charT , class traits >

virtual int_type RWTPortalStreambuf< charT, traits >::underflow ( void  )

protectedvirtual

Reads from the portal when the buffer underflows.
