Detailed Description

a class representing the DICOM value representation 'Attribute Tag' (AT)

Constructor & Destructor Documentation

DcmAttributeTag::DcmAttributeTag	(	const DcmTag &	tag,
		const Uint32	len = `0`
	)

constructor.

Create new element from given tag and length.

Parameters:

tag	DICOM tag for the new element
len	value length for the new element

DcmAttributeTag::DcmAttributeTag ( const DcmAttributeTag & old )

copy constructor

Parameters:

old	element to be copied

Member Function Documentation

static OFCondition DcmAttributeTag::checkStringValue	(	const OFString &	value,
		const OFString &	vm = `"1-n"`
	)		`[static]`

check whether given string value conforms to the VR "AT" (Attribute Tag) and to the specified VM.

Parameters:

value	string value to be checked (possibly multi-valued)
vm	value multiplicity (according to the data dictionary) to be checked for. (See DcmElement::checkVM() for a list of valid values.)

Returns:: status of the check, EC_Normal if value is correct, an error code otherwise

virtual OFCondition DcmAttributeTag::checkValue	(	const OFString &	vm = `"1-n"`,
		const OFBool	oldFormat = `OFFalse`
	)		`[virtual]`

check whether stored value conforms to the VR and to the specified VM

Parameters:

vm	value multiplicity (according to the data dictionary) to be checked for. (See DcmElement::checkVM() for a list of valid values.)
oldFormat	parameter not used for this VR (only for DA, TM, PN)

Returns:: status of the check, EC_Normal if value is correct, an error code otherwise

Reimplemented from DcmElement.

virtual DcmObject* DcmAttributeTag::clone ( ) const [inline, virtual]

clone method

Returns:: deep copy of this object

Implements DcmObject.

virtual OFCondition DcmAttributeTag::copyFrom ( const DcmObject & rhs ) [virtual]

Virtual object copying.

This method can be used for DcmObject and derived classes to get a deep copy of an object. Internally the assignment operator is called if the given DcmObject parameter is of the same type as "this" object instance. If not, an error is returned. This function permits copying an object by value in a virtual way which therefore is different to just calling the assignment operator of DcmElement which could result in slicing the object.

Parameters:

rhs	- [in] The instance to copy from. Has to be of the same class type as "this" object

Returns:: EC_Normal if copying was successful, error otherwise

Reimplemented from DcmElement.

virtual OFCondition DcmAttributeTag::getOFString	(	OFString &	stringVal,
		const unsigned long	pos,
		OFBool	normalize = `OFTrue`
	)		`[virtual]`

get specified value as a character string.

The output format is "(gggg,eeee)" where "gggg" is the hexa-decimal group number and "eeee" the hexa-decimal element number of the attribute tag.

Parameters:

stringVal	variable in which the result value is stored
pos	index of the value in case of multi-valued elements (0..vm-1)
normalize	not used

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

Reimplemented from DcmElement.

virtual OFCondition DcmAttributeTag::getTagVal	(	DcmTagKey &	tagVal,
		const unsigned long	pos = `0`
	)		`[virtual]`

get particular tag value

Parameters:

tagVal	reference to result variable (cleared in case of error)
pos	index of the value to be retrieved (0..vm-1)

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

Reimplemented from DcmElement.

virtual OFCondition DcmAttributeTag::getUint16Array ( Uint16 *& uintVals ) [virtual]

get reference to stored integer data.

The array entries with an even-numbered index contain the group numbers and the odd entries contain the element numbers (see "putUint16Array()"). The number of entries is twice as large as the return value of "getVM()".

Parameters:

uintVals reference to result variable

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

Reimplemented from DcmElement.

virtual unsigned long DcmAttributeTag::getVM ( ) [virtual]

get value multiplicity

Returns:: number of tag value pairs (group,element)

Implements DcmObject.

virtual DcmEVR DcmAttributeTag::ident ( ) const [virtual]

get element type identifier

Returns:: type identifier of this class (EVR_AT)

Implements DcmObject.

DcmAttributeTag& DcmAttributeTag::operator= ( const DcmAttributeTag & obj )

assignment operator

Parameters:

obj	element to be assigned/copied

Returns:: reference to this object

virtual void DcmAttributeTag::print	(	STD_NAMESPACE ostream &	out,
		const size_t	flags = `0`,
		const int	level = `0`,
		const char *	pixelFileName = `NULL`,
		size_t *	pixelCounter = `NULL`
	)		`[virtual]`

print element to a stream.

The output format of the value is a backslash separated sequence of group and element value pairs, e.g. "(0008,0020)\(0008,0030)"

Parameters:

out	output stream
flags	optional flag used to customize the output (see DCMTypes::PF_xxx)
level	current level of nested items. Used for indentation.
pixelFileName	not used
pixelCounter	not used

Implements DcmObject.

virtual OFCondition DcmAttributeTag::putString ( const char * stringVal ) [virtual]

set element value from the given character string.

The input string is expected to be a backslash separated sequence of attribute tags, e.g. "(0008,0020)\(0008,0030)". This is the same format as used by "print()".

Parameters:

stringVal input character string

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

Reimplemented from DcmElement.

virtual OFCondition DcmAttributeTag::putString	(	const char *	stringVal,
		const Uint32	stringLen
	)		`[virtual]`

set element value from the given character string.

The input string is expected to be a backslash separated sequence of attribute tags, e.g. "(0008,0020)\(0008,0030)". This is the same format as used by "print()". The length of the string has to be specified explicitly. The string can, therefore, also contain more than one NULL byte.

Parameters:

stringVal	input character string
stringLen	length of the string (number of characters without the trailing NULL byte)

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

Reimplemented from DcmElement.

virtual OFCondition DcmAttributeTag::putTagVal	(	const DcmTagKey &	tagVal,
		const unsigned long	pos = `0`
	)		`[virtual]`

set particular tag value

Parameters:

tagVal	tag value to be set
pos	index of the value to be set (0 = first position)

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

Reimplemented from DcmElement.

virtual OFCondition DcmAttributeTag::putUint16Array	(	const Uint16 *	uintVals,
		const unsigned long	numUints
	)		`[virtual]`

set element value to given integer array data.

The array entries with an even-numbered index are expected to contain the group numbers and the odd entries to contain the element numbers, e.g. {0x0008, 0x0020, 0x0008, 0x0030}. This function uses the same format as "getUint16Array()".

Parameters:

uintVals	unsigned integer data to be set
numUints	number of integer values to be set (should be even)

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

Reimplemented from DcmElement.

virtual OFCondition DcmAttributeTag::verify ( const OFBool autocorrect = OFFalse ) [virtual]

check the currently stored element value

Parameters:

autocorrect correct value length if OFTrue

Returns:: status, EC_Normal if value length is correct, an error code otherwise

Implements DcmObject.
