## Detailed Description

the list of referenced images contained in a presentation state (internal use only).

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

## ◆ addImageReference() [1/2]

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.

## ◆ addImageReference() [2/2]

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

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.
  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.

## ◆ clear()

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.

## ◆ clone()

DVPSReferencedImage_PList * DVPSReferencedImage_PList::clone | ( |  | ) |
| inline

clone method.

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

References DVPSReferencedImage_PList().

## ◆ findImageReference()

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.

## ◆ getImageReference()

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.

## ◆ isApplicable()

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.

## ◆ isValid()

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.

## ◆ matchesApplicability()

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.

## ◆ read()

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.

## ◆ removeFrameReference()

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

## ◆ removeImageReference() [1/2]

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.

## ◆ removeImageReference() [2/2]

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()

size_t DVPSReferencedImage_PList::size | ( |  | ) | const
| inline

gets the number of image references in this list.

Returns
  the number of image references.

References list_.

## ◆ write()

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.
