mitk::AbstractFileReader::AbstractFileReader	(	const CustomMimeType &	mimeType,
		const std::string &	description
	)

explicitprotected

Associate this reader instance with the given MIME type.

If mimeType does not provide an extension list, an already registered mime-type object is used. Otherwise, the first entry in the extensions list is used to construct a mime-type name and register it as a new CustomMimeType service object in the default implementation of RegisterMimeType().

Parameters

mimeType	The mime type this reader can read.
description	A human readable description of this reader.

Exceptions

std::invalid_argument if mimeType is empty.

std::string mitk::AbstractFileReader::GetLocalFileName ( ) const

protected

Get a local file name for reading.

This is a convenience method for readers which cannot work natively with input streams. If no input stream has been been set, this method just returns the result of GetLocation(). However, if SetLocation(std::string, std::istream*) has been called with a non-null input stream, this method writes the contents of the stream to a temporary file and returns the name of the temporary file.

The temporary file is deleted when either SetLocation(std::string, std::istream*) is called again with a different input stream or the destructor of this class is called.

This method does not validate file names set via SetInput(std::string).

Returns: A file path in the local file-system for reading.

std::vector< BaseData::Pointer > mitk::AbstractFileReader::Read ( )

overridepure virtual

Reads a path or stream and creates a list of BaseData objects.

This method must be implemented for each specific reader. Call GetInputStream() first and check for a non-null stream to read from. If the input stream is NULL, use GetInputLocation() to read from a local file-system path.

If the reader cannot use streams directly, use GetLocalFileName() instead.

Returns: The created BaseData objects.

Exceptions

mitk::Exception

DataStorage::SetOfObjects::Pointer mitk::AbstractFileReader::Read ( mitk::DataStorage & ds )

Parameters

ds	The DataStorage to which the data is added.

Returns: The set of added DataNodes to ds.

This method may be overridden by implementations to create or reconstructed a hierarchy of mitk::DataNode instances in the provided mitk::DataStorage.

us::ServiceRegistration< CustomMimeType > mitk::AbstractFileReader::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

Parameters

context

Returns

Exceptions

std::invalid_argument if context is NULL.

Definition at line 203 of file mitkAbstractFileReader.cpp.

us::ServiceRegistration< IFileReader > mitk::AbstractFileReader::RegisterService ( us::ModuleContext * context = us::GetModuleContext() )

Associate this reader with the MIME type returned by the current IMimeTypeProvider service for the provided extension if the MIME type exists, otherwise registers a new MIME type when RegisterService() is called.

If no MIME type for extension is already registered, a call to RegisterService() will register a new MIME type and associate this reader instance with it. The MIME type id can be set via SetMimeType() or it will be auto-generated using extension, having the form "application/vnd.mitk.<extension>".

Parameters

extension	The file extension (without a leading period) for which a registered mime-type object is looked up and associated with this reader instance.
description	A human readable description of this reader.

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

Set the service ranking for this file reader.

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