Detailed Description

template<typename CharType, typename Traits>
class mvIMPACT::acquire::GenICam::ODevFileStreamBuf< CharType, Traits >

Constructor & Destructor Documentation

ODevFileStreamBuf()

template<typename CharType , typename Traits >

ODevFileStreamBuf ( )

inline

Constructs a new mvIMPACT::acquire::GenICam::ODevFileStreamBuf object.

~ODevFileStreamBuf()

template<typename CharType , typename Traits >

~ODevFileStreamBuf ( )

inline

class destructor.

Member Function Documentation

close()

template<typename CharType , typename Traits >

filebuf_type * close ( void )

inline

Closes a file on the device.

Returns

• A pointer to itself if successful
• 0 otherwise

is_open()

template<typename CharType , typename Traits >

bool is_open ( void ) const

inline

Determines if a file is open.

Returns

• true if the file is open
• false otherwise

open()

template<typename CharType , typename Traits >

filebuf_type * open ( mvIMPACT::acquire::Device * pDev, const char * pFileName, std::ios_base::openmode mode )

inline

Opens a file on the device.

The member function calls rdbuf -> open(_Filename, _Mode | ios_base::in). If open fails, the function calls setstate(failbit), which may throw an ios_base::failure exception.

Parameters

pDev	A pointer to a mvIMPACT::acquire::Device object obtained from a mvIMPACT::acquire::DeviceManager object.
pFileName	Name of the file to open
mode	File open mode

overflow()

template<typename CharType , typename Traits >

int_type overflow ( int_type c = traits_type::eof() )

inlineprotected

sync()

template<typename CharType , typename Traits >

int sync ( void )

xsputn()

template<typename CharType , typename Traits >

std::streamsize xsputn ( const char_type * s, std::streamsize n )
