close()

void stromx::runtime::DirectoryFileInput::close ( )

virtual

Closes the file input. If this functions is not called the input is closed by the destructor.

Implements stromx::runtime::FileInput.

file()

std::istream & stromx::runtime::DirectoryFileInput::file ( )

virtual

Returns the input stream with the file representation of the data.

Exceptions

WrongState

If the input provider has not been correctly initialized or if openFile() has not been called before calling this function.

Implements stromx::runtime::InputProvider.

hasFile()

bool stromx::runtime::DirectoryFileInput::hasFile ( ) const

virtual

Returns true if a file representation of the data exists.

Implements stromx::runtime::InputProvider.

initialize()

void stromx::runtime::DirectoryFileInput::initialize ( const std::string &  text, const std::string &  filename  )

virtual

Initializes the file input to text and file data.

Parameters

text	The text data.
filename	The name of the file which contains the file data. Pass an empty string if no file should be provided.

Implements stromx::runtime::FileInput.

openFile()

std::istream & stromx::runtime::DirectoryFileInput::openFile ( const OpenMode  mode )

virtual

Opens the file representation of the data and returns the associated input stream.

Exceptions

NoInputFile	If no file is provided.
WrongState	If the input provider has not been correctly initialized or if this function has already been called.
FileAccessFailed	If the file could not be opened.

Implements stromx::runtime::InputProvider.

text()

std::istream & stromx::runtime::DirectoryFileInput::text ( )

virtual

Returns an input stream with the text representation of the data.

Exceptions
