Member Function Documentation

virtual OFCondition DcmUnsignedLongOffset::clear ( )
virtual

clear the currently stored value

Returns
status, EC_Normal if successful, an error code otherwise

Reimplemented from DcmElement.

virtual DcmObject* DcmUnsignedLongOffset::clone ( ) const
inlinevirtual

clone method

Returns
deep copy of this object

Reimplemented from DcmUnsignedLong.

References DcmUnsignedLongOffset().

virtual OFCondition DcmUnsignedLongOffset::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 DcmUnsignedLong.

virtual DcmObject* DcmUnsignedLongOffset::getNextRecord ( )
virtual

get stored object reference

Returns
pointer to the currently referenced object (might be NULL)
virtual DcmEVR DcmUnsignedLongOffset::ident ( ) const
virtual

get element type identifier

Returns
type identifier of this class (internal type: EVR_up)

Reimplemented from DcmUnsignedLong.

DcmUnsignedLongOffset& DcmUnsignedLongOffset::operator= ( const DcmUnsignedLongOffset )

assignment operator.

Parameters
theoffset to be copied
virtual DcmObject* DcmUnsignedLongOffset::setNextRecord ( DcmObject record)
virtual

set stored object reference

Parameters
recordpointer to the object to be referenced
Returns
pointer to the newly referenced object (might be NULL)
virtual OFCondition DcmUnsignedLongOffset::verify ( const OFBool  autocorrect = OFFalse)
virtual

check the currently stored element value

Parameters
autocorrectcorrect value length if OFTrue
Returns
status, EC_Normal if value length is correct, an error code otherwise

Reimplemented from DcmUnsignedLong.
