Constructor & Destructor Documentation

DcmDecimalString::DcmDecimalString	(	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

(

const DcmDecimalString &

old

)

copy constructor

Parameters:

old	element to be copied

Member Function Documentation

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

check whether given string value conforms to the VR "DS" (Decimal String) 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 DcmDecimalString::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* DcmDecimalString::clone

(

)

const [inline, virtual]

clone method

Returns:

deep copy of this object

Reimplemented from DcmByteString.

virtual OFCondition DcmDecimalString::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 DcmByteString.

virtual OFCondition DcmDecimalString::getFloat64	(	Float64 &	doubleVal,
		const unsigned long	pos = 0
	)		[virtual]

get particular float value

Parameters:

doubleVal	reference to result variable
pos	index of the value to be retrieved (0..vm-1)

Returns:

status, EC_Normal if successful, an error code otherwise

Reimplemented from DcmElement.

virtual OFCondition DcmDecimalString::getFloat64Vector

(

OFVector< Float64 > &

doubleVals

)

[virtual]

get stored float values as a vector.

Please note that only an element value consisting of zero or more spaces is considered as being empty and, therefore, results in an empty vector with status ".good()"; use isEmpty() before calling this method if you also want to check for other non-significant characters (e.g. the backslash).

Parameters:

doubleVals

reference to result variable (cleared automatically before entries are added)

Returns:

status, EC_Normal if successful, an error code otherwise

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

get a particular value as a character string

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	delete leading and trailing spaces if OFTrue

Returns:

status, EC_Normal if successful, an error code otherwise

Reimplemented from DcmByteString.

virtual DcmEVR DcmDecimalString::ident

(

)

const [virtual]

get element type identifier

Returns:

type identifier of this class (EVR_DS)

Reimplemented from DcmByteString.

DcmDecimalString& DcmDecimalString::operator=

(

const DcmDecimalString &

obj

)

assignment operator

Parameters:

obj	element to be assigned/copied

Returns:

reference to this object

virtual OFCondition DcmDecimalString::writeXML	(	STD_NAMESPACE ostream &	out,
		const size_t	flags = 0
	)		[virtual]

write object in XML format

Parameters:

out	output stream to which the XML document is written
flags	optional flag used to customize the output (see DCMTypes::XF_xxx)

Returns:

status, EC_Normal if successful, an error code otherwise

Reimplemented from DcmElement.
