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 [inline, virtual]

clone method

Returns:

deep copy of this object

Reimplemented from DcmUnsignedLong.

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:

the	offset to be copied

virtual DcmObject* DcmUnsignedLongOffset::setNextRecord

(

DcmObject *

record

)

[virtual]

set stored object reference

Parameters:

record

pointer 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:

autocorrect

correct value length if OFTrue

Returns:

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

Reimplemented from DcmUnsignedLong.
