Member Function Documentation

virtual DcmObject* DcmOverlayData::clone

(

)

const [inline, virtual]

clone method

Returns:

deep copy of this object

Reimplemented from DcmPolymorphOBOW.

virtual OFCondition DcmOverlayData::copyFrom

(

const DcmObject &

rhs

)

[inline, 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 DcmPolymorphOBOW.

virtual DcmEVR DcmOverlayData::ident

(

void

)

const [inline, virtual]

return identifier for this class.

Every class derived from this class returns a unique value of type enum DcmEVR for this call. This is used as a "poor man's RTTI" to correctly identify instances derived from this class even on compilers not supporting RTTI.

Returns:

type identifier of this class

Reimplemented from DcmOtherByteOtherWord.

DcmOverlayData& DcmOverlayData::operator=

(

const DcmOverlayData &

obj

)

[inline]

copy assignment operator

Parameters:

obj	element to be copied
