Detailed Description

Base class for writing mitk::BaseData objects to files or streams.

In general, all file writers should derive from this class, this way it is made sure that the new implementation is exposed to the Microservice-Framework and that is automatically available troughout MITK. The default implementation only requires one Write() method and the Clone() method to be implemented.

◆ AddProgressCallback()

void mitk::AbstractFileWriter::AddProgressCallback ( const ProgressCallback callback)

Implements mitk::IFileIO.

◆ GetBaseDataType()

virtual std::string mitk::AbstractFileWriter::GetBaseDataType ( ) const

◆ GetConfidenceLevel()

ConfidenceLevel mitk::AbstractFileWriter::GetConfidenceLevel ( ) const

The confidence level of the reader or writer implementation.

Confidence level.

The level is used to rank multiple competing implementations.

Implements mitk::IFileIO.

Reimplemented in mitk::LegacyFileWriterService.

Referenced by mitk::AbstractFileIOWriter::GetWriterConfidenceLevel().

◆ GetDefaultOptions()

Options mitk::AbstractFileWriter::GetDefaultOptions ( ) const

◆ GetDescription()

std::string mitk::AbstractFileWriter::GetDescription ( ) const

◆ GetInput()

const BaseData* mitk::AbstractFileWriter::GetInput ( ) const

Get the input data set via SetInput().

The input data.

Implements mitk::IFileWriter.

◆ GetMimeType()

const CustomMimeType* mitk::AbstractFileWriter::GetMimeType ( ) const
Get the mime-type this writer can handle.

◆ GetMimeTypePrefix()

std::string mitk::AbstractFileWriter::GetMimeTypePrefix ( ) const

◆ GetOption()

us::Any mitk::AbstractFileWriter::GetOption ( const std::string &  name) const

Implements mitk::IFileIO.

◆ GetOptions()

Options mitk::AbstractFileWriter::GetOptions ( ) const

returns a list of the supported options

Options are strings that are treated as flags when passed to the write method.

Implements mitk::IFileIO.

◆ GetOutputLocation()

std::string mitk::AbstractFileWriter::GetOutputLocation ( ) const

Get the current output location.

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.

Implements mitk::IFileWriter.

◆ GetOutputStream()

std::ostream* mitk::AbstractFileWriter::GetOutputStream ( ) const

Get the output stream.

The currently set output stream.

Implements mitk::IFileWriter.

◆ GetRanking()

int mitk::AbstractFileWriter::GetRanking ( ) const

◆ GetRegisteredMimeType()

MimeType mitk::AbstractFileWriter::GetRegisteredMimeType ( ) const

◆ GetServiceProperties()

virtual us::ServiceProperties mitk::AbstractFileWriter::GetServiceProperties ( ) const

◆ RegisterMimeType()

virtual us::ServiceRegistration<CustomMimeType> mitk::AbstractFileWriter::RegisterMimeType ( us::ModuleContext *  context)

Registers a new CustomMimeType service object.

This method is called from RegisterService and the default implementation registers a new mime-type service object if all of the following conditions are true:

  • TODO
std::invalid_argumentif context is nullptr.

◆ RegisterService()

us::ServiceRegistration<IFileWriter> mitk::AbstractFileWriter::RegisterService ( us::ModuleContext *  context = us::GetModuleContext())

◆ RemoveProgressCallback()

void mitk::AbstractFileWriter::RemoveProgressCallback ( const ProgressCallback callback)

Implements mitk::IFileIO.

◆ SetBaseDataType()

void mitk::AbstractFileWriter::SetBaseDataType ( const std::string &  baseDataType)

Sets the name of the mitk::Basedata that this writer is able to handle.

The correct value is the one given as the first parameter in the mitkNewMacro of that BaseData derivate. You can also retrieve it by calling GetNameOfClass() on an instance of said data.

◆ SetDefaultOptions()

void mitk::AbstractFileWriter::SetDefaultOptions ( const Options defaultOptions)

◆ SetDescription()

void mitk::AbstractFileWriter::SetDescription ( const std::string &  description)

Sets a human readable description of this writer.

This will be used in file dialogs for example.

◆ SetInput()

void mitk::AbstractFileWriter::SetInput ( const BaseData data)

Set the input data for writing.

dataThe input data.

Implements mitk::IFileWriter.

◆ SetMimeType()

void mitk::AbstractFileWriter::SetMimeType ( const CustomMimeType mimeType)

◆ SetMimeTypePrefix()

void mitk::AbstractFileWriter::SetMimeTypePrefix ( const std::string &  prefix)

◆ SetOption()

void mitk::AbstractFileWriter::SetOption ( const std::string &  name,
const us::Any value 

Implements mitk::IFileIO.

◆ SetOptions()

void mitk::AbstractFileWriter::SetOptions ( const Options options)

Implements mitk::IFileIO.

◆ SetOutputLocation()

void mitk::AbstractFileWriter::SetOutputLocation ( const std::string &  location)

Set the output location.

locationA 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.

Implements mitk::IFileWriter.

◆ SetOutputStream()

void mitk::AbstractFileWriter::SetOutputStream ( const std::string &  location,
std::ostream *  os 

Set an output stream for writing.

locationA custom label for the output stream.
osThe 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.

Implements mitk::IFileWriter.

◆ SetRanking()

void mitk::AbstractFileWriter::SetRanking ( int  ranking)

Set the service ranking for this file writer.

Default is zero and should only be chosen differently for a reason. The ranking is used to determine which writer to use if several equivalent writers have been found. It may be used to replace a default writer from MITK in your own project. E.g. if you want to use your own writer for nrrd files instead of the default, implement it and give it a higher ranking than zero.

◆ UnregisterService()

void mitk::AbstractFileWriter::UnregisterService ( )

◆ ValidateOutputLocation()

void mitk::AbstractFileWriter::ValidateOutputLocation ( ) const

◆ Write()

void mitk::AbstractFileWriter::Write ( )
overridepure virtual

Write the base data to the specified location or output stream.

This method must be implemented for each specific writer. Call GetOutputStream() first and check for a non-null stream to write to. If the output stream is nullptr, use GetOutputLocation() to write to a local file-system path.

If the reader cannot use streams directly, use GetLocalFile() to retrieve a temporary local file name instead.
