Detailed Description

The common interface of all MITK file writers.

Implementations of this interface must be registered as a service to make themselves available via the service registry. If the implementation is stateful, the service should be registered using a PrototypeServiceFactory.

The file writer implementation is associated with a mime-type, specified in the service property PROP_MIMETYPE() and a mitk::BaseData sub-class as specified in the PROP_BASEDATA_TYPE() service property. The specified mime-type should have a corresponding CustomMimeType service object, registered by the reader or some other party.

It is recommended to derive new implementations from AbstractFileWriter or AbstractFileIO (if both reader and writer is implemented), which provide correct service registration semantics.

A more in-depth explanation is available on the concepts pages in the developer manual.

Constructor & Destructor Documentation

◆ ~IFileWriter()

mitk::IFileWriter::~IFileWriter ( )

override

Member Function Documentation

◆ GetInput()

virtual const BaseData* mitk::IFileWriter::GetInput ( ) const

pure virtual

Get the input data set via SetInput().

Returns: The input data.

Implemented in mitk::AbstractFileWriter.

◆ GetOutputLocation()

virtual std::string mitk::IFileWriter::GetOutputLocation ( ) const

pure virtual

Get the current output location.

Returns: The output location.

If no stream is set (i.e. GetOutputStream returns nullptr), the returned location string is required to represent a file-system path.

Implemented in mitk::AbstractFileWriter.

◆ GetOutputStream()

virtual std::ostream* mitk::IFileWriter::GetOutputStream ( ) const

pure virtual

Get the output stream.

Returns: The currently set output stream.

Implemented in mitk::AbstractFileWriter.

◆ PROP_BASEDATA_TYPE()

static std::string mitk::IFileWriter::PROP_BASEDATA_TYPE ( )

static

Service property name for the supported mitk::BaseData sub-class.

The property value must be of type std::string.

Returns: The property name.

◆ SetInput()

virtual void mitk::IFileWriter::SetInput ( const BaseData * data )

pure virtual

Set the input data for writing.

Parameters

data	The input data.

Implemented in mitk::AbstractFileWriter.

◆ SetOutputLocation()

virtual void mitk::IFileWriter::SetOutputLocation ( const std::string & location )

pure virtual

Set the output location.

Parameters

location A file-system path.

The location argument specifies a file-system path where the input data must be written. This method must remove any previously set output stream.

Implemented in mitk::AbstractFileWriter.

◆ SetOutputStream()

virtual void mitk::IFileWriter::SetOutputStream	(	const std::string &	location,
		std::ostream *	os
	)

pure virtual

Set an output stream for writing.

Parameters

location	A custom label for the output stream.
os	The output stream.

If os is nullptr, this clears the current output stream and location is interpreted as a file-system path. Otherwise, location is a custom label describing the output stream os.

Implemented in mitk::AbstractFileWriter.

◆ Write()

virtual void mitk::IFileWriter::Write ( )

pure virtual

Write the input data.

If GetOutputStream() returns a non-null value, this method must use the returned stream object to write the data set via SetInput(). If no output stream was set, the data must be written to the path returned by GetOutputLocation().
