Detailed Description

Generic interface for standard and user written I/O handlers.

Qwt3DIO provides a generic interface for standard and user written I/O handlers. It also provides functionality for the registering of such handlers in the framework. The interface mimics roughly Qt's QImageIO functions for defining image input/output functions.

Member Function Documentation

defineInputHandler() [1/2]

bool Qwt3DIO::defineInputHandler ( QString const &  format, Qwt3DIO::Function  func  )

static

Registers a new Qwt3DIO::Function for data input.

Parameters

format	Format string identifier
func	Input handler function

Returns

True on successful registration

Every call overwrites a formerly registered handler for the same format string (case sensitive).

defineInputHandler() [2/2]

bool Qwt3DIO::defineInputHandler ( QString const &  format, Qwt3DIO::Functor const &  func  )

static

Registers a new Functor for data input.

Parameters

format	Format string identifier
func	Input handler functor

Returns

True on successful registration

Every call overwrites a formerly registered handler for the same format string (case sensitive).

defineOutputHandler() [1/2]

bool Qwt3DIO::defineOutputHandler ( QString const &  format, Qwt3DIO::Function  func  )

static

Registers a new Qwt3DIO::Function for data output.

Parameters

format	Format string identifier
func	Output handler function

Returns

True on successful registration

Every call overwrites a formerly registered handler for the same format string (case sensitive).

defineOutputHandler() [2/2]

bool Qwt3DIO::defineOutputHandler ( QString const &  format, Qwt3DIO::Functor const &  func  )

static

Registers a new Functor for data output.

Parameters

format	Format string identifier
func	Output handler functor

Returns

True on successful registration

Every call overwrites a formerly registered handler for the same format string (case sensitive).

inputFormatList()

QStringList Qwt3DIO::inputFormatList ( )

static

Returns a list of currently registered input formats.

Returns

List of input format strings

inputHandler()

Qwt3DIO::Functor * Qwt3DIO::inputHandler ( QString const &  format )

static

Returns the input functor in charge for format.

Parameters

format

Format string identifier

Returns

Pointer to the input functor, or 0 if non-existent

load()

bool Qwt3DIO::load ( Qwt3DPlot *  plot, QString const &  fname, QString const &  format  )

static

Applies a reading Qwt3DIO::Function or Qwt3DIO::Functor.

Parameters

plot	Plot with the content that should be loaded
fname	File name
format	Input format

Returns

The return value from the called Function/Functor. Returns false if no registered handler could be found.

outputFormatList()

QStringList Qwt3DIO::outputFormatList ( )

static

Returns a list of currently registered output formats.

Returns

List of output format strings

outputHandler()

Qwt3DIO::Functor * Qwt3DIO::outputHandler ( QString const &  format )

static

Returns the output functor in charge for format.

Parameters

format

Format string identifier

Returns

Pointer to the output functor, or 0 if non-existent

save()

bool Qwt3DIO::save ( Qwt3DPlot *  plot, QString const &  fname, QString const &  format  )

static

Applies a writing Qwt3DIO::Function or Qwt3DIO::Functor.

Parameters

plot	Plot with the content that should be saved
fname	File name
format	Output format

Returns

The return value from the called Function/Functor. Returns false if no registered handler could be found.
