constructor

Parameters

DSRCompositeReferenceValue::DSRCompositeReferenceValue | ( | const DSRCompositeReferenceValue & | referenceValue | ) |

copy constructor

Parameters

References DSRCompositeReferenceValue().

## Member Function Documentation

## ◆ checkCurrentValue()

OFCondition DSRCompositeReferenceValue::checkCurrentValue | ( | const OFBool | reportWarnings = OFFalse | ) | const
| protected

check the currently stored reference value for validity.

See above checkXXX() methods for details.

Parameters

  reportWarnings | if enabled, report a warning message on each deviation from an expected value to the logger

Returns
  status, EC_Normal if current value is valid, an error code otherwise

## ◆ checkSOPClassUID()

virtual OFCondition DSRCompositeReferenceValue::checkSOPClassUID | ( | const OFString & | sopClassUID,
|  | const OFBool | reportWarnings = OFFalse ) const
| protectedvirtual

check the specified SOP class UID for validity.

The only checks performed are that the UID is non-empty and that it conforms to the corresponding VR (UI) and VM (1). Derived classes should overwrite this method for more specific tests (e.g. allowing only particular SOP classes).

Parameters

  sopClassUID | SOP class UID to be checked
  reportWarnings | if enabled, report warning messages to the logger

Returns
  status, EC_Normal if value is valid, an error code otherwise

virtual OFCondition DSRCompositeReferenceValue::checkSOPInstanceUID | ( | const OFString & | sopInstanceUID,
|  | const OFBool | reportWarnings = OFFalse ) const
| protectedvirtual

check the specified SOP instance UID for validity.

The only checks performed are that the UID is non-empty and that it conforms to the corresponding VR (UI) and VM (1). Derived classes should overwrite this method for more specific tests.

Parameters
