Detailed Description

This class manages the data structures comprising one complete Reference Image Sequence which is contained in one item of the Referenced Series Sequence in a Presentation State object.

Member Function Documentation

DVPSReferencedImage_PList* DVPSReferencedImage_PList::clone ( ) [inline]

clone method.

Returns:: a pointer to a new DVPSReferencedImage_PList object containing a deep copy of this object.

Definition at line 59 of file dvpsril.h.

References DVPSReferencedImage_PList().

OFCondition DVPSReferencedImage_PList::read ( DcmItem & dset )

reads a list of image references (ReferencedImageSequence) from a DICOM dataset.

The DICOM elements of the image references item are copied from the dataset to this object. The completeness of all items (presence of all required elements, value multiplicity) is checked. If this method returns an error code, the object is in undefined state afterwards.

Parameters:

dset

the DICOM dataset from which the sequence is to be read

Returns:: EC_Normal if successful, an error code otherwise.

OFCondition DVPSReferencedImage_PList::write ( DcmItem & dset )

writes the list of image references managed by this object to a DICOM dataset.

Copies of the DICOM element managed by this object are inserted into the DICOM dataset.

Parameters:

dset

the DICOM dataset to which the ReferencedImageSequence is written

Returns:: EC_Normal if successful, an error code otherwise.

void DVPSReferencedImage_PList::clear ( )

reset the object to initial state.

After this call, the object is in the same state as after creation with the default constructor.

Referenced by DVPSSoftcopyVOI::clearImageReferences(), and DVPSDisplayedArea::clearImageReferences().

OFBool DVPSReferencedImage_PList::isValid ( OFString & sopclassuid )

checks if images are referenced within this ReferencedImageSequence and whether all images share the same SOP class UID.

Parameters:

sopclassuid

should be an empty string when called. Returns the SOP class UID of the images in the list.

Returns:: OFTrue if the sequence is valid (correct), OFFalse otherwise.

DVPSReferencedImage* DVPSReferencedImage_PList::findImageReference ( const char * sopinstanceuid )

checks if an image reference with the given SOP instance UID exists in this ReferencedImageSequence.

Parameters:

sopinstanceuid

the SOP instance UID of the searched image reference

Returns:: a pointer to the matching DVPSReferencedImage if found, NULL otherwise.

void DVPSReferencedImage_PList::removeFrameReference	(	const char *	sopinstanceuid,
		unsigned long	frame,
		unsigned long	numberOfFrames
	)

update the reference to the given image such that the given frame is not referenced any more.

Parameters:

	sopinstanceuid	the SOP instance UID of the image reference
	frame	the frame reference
	numberOfFrames	the number of frames of the image reference

void DVPSReferencedImage_PList::removeImageReference ( const char * sopinstanceuid )

checks if an image reference with the given SOP instance UID exists in this ReferencedImageSequence and deletes it.

Parameters:

sopinstanceuid

the SOP instance UID of the image reference to be removed.

OFCondition DVPSReferencedImage_PList::addImageReference	(	const char *	sopclassUID,
		const char *	instanceUID,
		const char *	frames = `NULL`
	)

add a new image reference.

Checks if the referenced SOP instance UID already exists in this sequence. If it exists, an error code is returned. Otherwise a new image reference is created and added to the ReferencedImageSequence.

Parameters:

	sopclassUID	the SOP class UID of the image reference to be added.
	instanceUID	the SOP instance UID of the image reference to be added.
	frames	a list of frame numbers in DICOM IS format (integer numbers separated by '\' characters). Default: frame numbers absent. The frame numbers are required if the referenced image is a multiframe image.

OFCondition DVPSReferencedImage_PList::addImageReference	(	const char *	sopclassUID,
		const char *	instanceUID,
		unsigned long	frame,
		DVPSObjectApplicability	applicability
	)

add a new image reference.

Parameters:

	sopclassUID	the SOP class UID of the image reference to be added.
	instanceUID	the SOP instance UID of the image reference to be added.
	frame	the frame number of the image reference (current image) to be added.
	applicability	the applicability of the image reference (DVPSB_currentFrame or DVPSB_currentImage)

Returns:: EC_Normal if successful, an error code otherwise.

void DVPSReferencedImage_PList::removeImageReference	(	DVPSReferencedSeries_PList &	allReferences,
		const char *	instanceUID,
		unsigned long	frame,
		unsigned long	numberOfFrames,
		DVPSObjectApplicability	applicability
	)

removes a reference to an image or frame.

If the current reference is empty ("global"), an explicit list of references is constructed from the list of series/instance references. The image or frame reference is removed from the total list of references in this object. If the only reference contained in this object is removed, the reference list becomes empty which means that the current reference becomes "global". This case must be handled by the caller.

Parameters:

	allReferences	list of series/instance references registered for the presentation state.
	instanceUID	SOP instance UID of the current image
	frame	number of the current frame
	numberOfFrames	the number of frames of the current image
	applicability	the applicability of the image reference to be removed (DVPSB_currentFrame or DVPSB_currentImage)

size_t DVPSReferencedImage_PList::size ( ) const [inline]

gets the number of image references in this list.

Returns:: the number of image references.

Definition at line 170 of file dvpsril.h.

References list_, and OFList< T >::size().

Referenced by DVPSSoftcopyVOI::imageReferencesEmpty(), DVPSDisplayedArea::imageReferencesEmpty(), and DVPSReferencedSeries::numberOfImageReferences().

OFCondition DVPSReferencedImage_PList::getImageReference	(	size_t	idx,
		OFString &	sopclassUID,
		OFString &	instanceUID,
		OFString &	frames
	)

gets an image reference with the given index.

Parameters:

	idx	index, must be < size().
	sopclassUID	the SOP Class UID is returned in this string
	instanceUID	the SOP Instance UID is returned in this string
	frames	the list of frames is returned in this string

Returns:: EC_Normal if successful, an error code otherwise.

OFBool DVPSReferencedImage_PList::isApplicable	(	const char *	instanceUID,
		unsigned long	frame
	)

checks if the object containing this list of image references is applicable to the given image and frame.

Parameters:

	instanceUID	SOP instance UID of the current image
	frame	number of the current frame

Returns:: OFTrue if applicable.

OFBool DVPSReferencedImage_PList::matchesApplicability	(	const char *	instanceUID,
		unsigned long	frame,
		DVPSObjectApplicability	applicability
	)

checks if the object containing this list of image references matches exactly the applicability defined by the instanceUID, frame and applicability parameters.

Parameters:

	instanceUID	SOP instance UID of the current image
	frame	number of the current frame

Returns:: OFTrue if matching.
