Private Attributes | |
| DcmVR | vr |
| VR of this attribute tag. | |
| char * | tagName |
| name of this attribute tag, remains NULL unless getTagName() is called | |
| char * | privateCreator |
| private creator code, remains NULL unless setPrivateCreator() is called | |
| OFCondition | errorFlag |
| current error code, EC_Normal if a valid VR for the tag is known | |
It maintains a private creator name for private tags and caches the attribute name, once it is looked up in the data dictionary. This class maintains the interface to the DICOM data dictionary, i.e. performs look-ups of attribute VR and name in the background. Therefore, creation of DcmTag element is significantly more expensive than creation of simple DcmTagKey objects unless the VR is passed in the constructor.

| DcmTag::DcmTag | ( | const DcmTagKey & | akey | ) |
constructor.
Initializes group/element from given tag key and performs a dictionary lookup for the VR. The lookup only considers standard tags, tags with private creator are ignored.
| akey | tag key |
| DcmTag::DcmTag | ( | Uint16 | g, | |
| Uint16 | e | |||
| ) |
constructor.
Initializes group/element from given parameters and performs a dictionary lookup for the VR. The lookup only considers standard tags, tags with private creator are ignored.
| g | tag group | |
| e | tag element |
constructor.
Initializes group/element and VR from given parameters. No dictionary lookup needed/performed.
| akey | tag key | |
| avr | VR |
| DcmTag::DcmTag | ( | Uint16 | g, | |
| Uint16 | e, | |||
| const DcmVR & | avr | |||
| ) |
constructor.
Initializes group/element and VR from given parameters. No dictionary lookup needed/performed.
| g | tag group | |
| e | tag element | |
| avr | VR |
| Uint16 DcmTag::getGTag | ( | ) | const [inline] |
returns tag group

| Uint16 DcmTag::getETag | ( | ) | const [inline] |
returns tag element

| DcmTagKey DcmTag::getXTag | ( | ) | const [inline] |
| const char* DcmTag::getTagName | ( | ) |
returns name of attribute tag.
If name has not been accessed before, a dictionary lookup under consideration of the current private creator code is performed. If no attribute name is found, a default name is used. Never returns NULL.
Referenced by I2DOutputPlug::checkAndInventType1Attrib(), I2DOutputPlug::checkAndInventType2Attrib(), and DcmObject::getTagName().
| const char* DcmTag::getPrivateCreator | ( | ) | const |
returns the current private creator string for this object if any, NULL otherwise.
| void DcmTag::setPrivateCreator | ( | const char * | privCreator | ) |
assigns a private creator code and deletes a possibly cached attribute name since the attribute name could change if a different private creator code is used.
| privCreator | private creator code, may be NULL |
| void DcmTag::lookupVRinDictionary | ( | ) |
performs a look-up of the VR for the current tag key in the dictionary, under consideration of the private creator (if defined).
If a dictionary entry is found, the VR of this object is copied from the dictionary entry, otherwise the VR remains unmodified.
| OFBool DcmTag::isSignable | ( | ) | const |
returns true if a data element with the given tag and VR can be digitally signed, false otherwise
| static OFCondition DcmTag::findTagFromName | ( | const char * | name, | |
| DcmTag & | value | |||
| ) | [static] |
convert the given string to a DICOM tag value
| name | name or tag of the attribute to be searched for. If the name of the attribute is given the spelling has to be consistent with the spelling used in the data dictionary (e.g. "PatientName"). If the tag values are used the format is "gggg,eeee" (i.e. two hexa- decimal numbers separated by a comma). | |
| value | variable in which the resulting tag value is stored. If this functions fails to find the specified tag, this variable remains unchanged. |
| void DcmTag::updateTagName | ( | const char * | c | ) | [private] |
replace tagName with copy of given string
| c | new tag name |
| void DcmTag::updatePrivateCreator | ( | const char * | c | ) | [private] |
replace privateCreator with copy of given string
| c | new private creator |
