Member Function Documentation

virtual void itk::LightProcessObject::AbortGenerateDataOff ( ) [virtual, inherited]

virtual void itk::LightProcessObject::AbortGenerateDataOn ( ) [virtual, inherited]

Turn on and off the AbortGenerateData flag.

unsigned long itk::Object::AddObserver	(	const EventObject &	event,
		Command *
	)			`[inherited]`

Allow people to add/remove/invoke observers (callbacks) to any ITK object. This is an implementation of the subject/observer design pattern. An observer is added by specifying an event to respond to and an itk::Command to execute. It returns an unsigned long tag which can be used later to remove the event or retrieve the command. The memory for the Command becomes the responsibility of this object, so don't pass the same instance of a command to two different objects

unsigned long itk::Object::AddObserver	(	const EventObject &	event,
		Command *
	)			const `[inherited]`

Allow people to add/remove/invoke observers (callbacks) to any ITK object. This is an implementation of the subject/observer design pattern. An observer is added by specifying an event to respond to and an itk::Command to execute. It returns an unsigned long tag which can be used later to remove the event or retrieve the command. The memory for the Command becomes the responsibility of this object, so don't pass the same instance of a command to two different objects

void itk::ImageIOBase::AddSupportedReadExtension ( const char * extension ) [protected, inherited]

Insert an extension to the list of supported extensions for reading.

void itk::ImageIOBase::AddSupportedWriteExtension ( const char * extension ) [protected, inherited]

Insert an extension to the list of supported extensions for writing.

static void itk::LightObject::BreakOnError ( ) [static, inherited]

Determine the file type. Returns true if this ImageIO can read the file specified.

Implements itk::ImageIOBase.

virtual bool itk::MetaImageIO::CanStreamRead ( void ) [inline, virtual]

Determine if the ImageIO can stream reading from this file. Only time cannot stream read/write is if compression is used. CanRead must be called prior to this function.

Reimplemented from itk::ImageIOBase.

Definition at line 123 of file itkMetaImageIO.h.

virtual bool itk::MetaImageIO::CanStreamWrite ( void ) [inline, virtual]

Determine if the ImageIO can stream writing to this file. Only time cannot stream read/write is if compression is used. Assumes file passes a CanRead call and its pixels are of the same type as the template of the writer. Can verify by first calling CanRead and then CanStreamRead prior to calling CanStreamWrite.

Reimplemented from itk::ImageIOBase.

Definition at line 138 of file itkMetaImageIO.h.

virtual bool itk::MetaImageIO::CanWriteFile ( const char * ) [virtual]

Determine the file type. Returns true if this ImageIO can write the file specified.

Implements itk::ImageIOBase.

void itk::ImageIOBase::ComputeStrides ( ) [protected, inherited]

Calculates the different strides (distance from one thing to the next). Upon return, strides[0] = bytes to get to the next component of a pixel, strides[1] = bytes to get to the next pixel in x direction, strides[2] = bytes to get to the next row in y direction, strides[3] = bytes to get to the next slice in z direction, etc.

virtual LightObject::Pointer itk::Object::CreateAnother ( ) const [virtual, inherited]

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::LightObject.

virtual void itk::Object::DebugOff ( ) const [virtual, inherited]

Turn debugging output off.

virtual void itk::Object::DebugOn ( ) const [virtual, inherited]

Turn debugging output on.

virtual void itk::LightObject::Delete ( ) [virtual, inherited]

Delete an itk object. This method should always be used to delete an object when the new operator was used to create it. Using the C delete method will not work with reference counting.

virtual void itk::LightProcessObject::GenerateData ( void ) [inline, protected, virtual, inherited]

This method causes the filter to generate its output.

Reimplemented in itk::ClassifierBase< TDataContainer >, itk::ImageClassifierBase< TInputImage, TClassifiedImage >, itk::ImageGaussianModelEstimator< TInputImage, TMembershipFunction, TTrainingImage >, itk::ImageKmeansModelEstimator< TInputImage, TMembershipFunction >, itk::ImageModelEstimatorBase< TInputImage, TMembershipFunction >, itk::LevelSetNeighborhoodExtractor< TLevelSet >, itk::Statistics::SampleClassifier< TSample >, itk::Statistics::SampleClassifierWithMask< TSample, TMaskSample >, itk::ClassifierBase< TInputImage >, and itk::ClassifierBase< TSample >.

Definition at line 123 of file itkLightProcessObject.h.

virtual ImageIORegion itk::MetaImageIO::GenerateStreamableReadRegionFromRequestedRegion ( const ImageIORegion & requested ) const [virtual]

Method for supporting streaming. Given a requested region, calculate what could be the region that we can read from the file. This is called the streamable region, which will be smaller than the LargestPossibleRegion and greater or equal to the RequestedRegion

Reimplemented from itk::ImageIOBase.

virtual const bool& itk::LightProcessObject::GetAbortGenerateData ( ) [virtual, inherited]

Get the AbortGenerateData flag for the process object. Process objects may handle premature termination of execution in different ways.

virtual unsigned int itk::MetaImageIO::GetActualNumberOfSplitsForWriting	(	unsigned int	numberOfRequestedSplits,
		const ImageIORegion &	pasteRegion,
		const ImageIORegion &	largestPossibleRegion
	)			`[virtual]`

Before this method is called all the configuration will be done, that is Streaming/PasteRegion/Compression/Filename etc If pasting is being used the number of requested splits is for that region not the largest. The derived ImageIO class should verify that the file is capable of being writen with this configuration. If pasted is enabled and is not support or does not work with the file, then an excepetion should be thrown.

The default implementation depends on CanStreamWrite. If false then 1 is returned (unless pasting is indicated), so that the whole file will be updated in one region. If true then its assumed that any arbitrary region can be writen to any file. So the users request will be respected. If a derived class has more restictive conditions then they should be checked

Reimplemented from itk::ImageIOBase.

virtual unsigned int itk::ImageIOBase::GetActualNumberOfSplitsForWritingCanStreamWrite	(	unsigned int	numberOfRequestedSplits,
		const ImageIORegion &	pasteRegion
	)			const `[protected, virtual, inherited]`

virtual ByteOrder itk::ImageIOBase::GetByteOrder ( ) const [virtual, inherited]

These methods indicate the byte ordering of the file you are trying to read in. These methods will then either swap or not swap the bytes depending on the byte ordering of the machine it is being run on. For example, reading in a BigEndian file on a BigEndian machine will result in no swapping. Trying to read the same file on a LittleEndian machine will result in swapping. Note: most UNIX machines are BigEndian while PC's and VAX's are LittleEndian. So if the file you are reading in was generated on a VAX or PC, SetByteOrderToLittleEndian() otherwise SetByteOrderToBigEndian(). Some ImageIOBase subclasses ignore these methods.

std::string itk::ImageIOBase::GetByteOrderAsString ( ByteOrder ) const [inherited]

Convenience method returns the ByteOrder as a string. This can be used for writing output files.

Command* itk::Object::GetCommand ( unsigned long tag ) [inherited]

Get the command associated with the given tag. NOTE: This returns a pointer to a Command, but it is safe to asign this to a Command::Pointer. Since Command inherits from LightObject, at this point in the code, only a pointer or a reference to the Command can be used.

virtual void itk::ImageIOBase::SetByteOrder ( const ByteOrder _arg ) [virtual, inherited]

These methods indicate the byte ordering of the file you are trying to read in. These methods will then either swap or not swap the bytes depending on the byte ordering of the machine it is being run on. For example, reading in a BigEndian file on a BigEndian machine will result in no swapping. Trying to read the same file on a LittleEndian machine will result in swapping. Note: most UNIX machines are BigEndian while PC's and VAX's are LittleEndian. So if the file you are reading in was generated on a VAX or PC, SetByteOrderToLittleEndian() otherwise SetByteOrderToBigEndian(). Some ImageIOBase subclasses ignore these methods.

void itk::ImageIOBase::SetByteOrderToBigEndian ( ) [inline, inherited]

These methods indicate the byte ordering of the file you are trying to read in. These methods will then either swap or not swap the bytes depending on the byte ordering of the machine it is being run on. For example, reading in a BigEndian file on a BigEndian machine will result in no swapping. Trying to read the same file on a LittleEndian machine will result in swapping. Note: most UNIX machines are BigEndian while PC's and VAX's are LittleEndian. So if the file you are reading in was generated on a VAX or PC, SetByteOrderToLittleEndian() otherwise SetByteOrderToBigEndian(). Some ImageIOBase subclasses ignore these methods.
