Member Function Documentation

virtual const char* DJLSRepresentationParameter::className

(

)

const [virtual]

returns the class name as string.

can be used in operator== as poor man's RTTI replacement.

Implements DcmRepresentationParameter.

virtual DcmRepresentationParameter* DJLSRepresentationParameter::clone

(

)

const [virtual]

this methods creates a copy of type DcmRepresentationParameter * it must be overweritten in every subclass.

Returns:

copy of this object

Implements DcmRepresentationParameter.

Uint16 DJLSRepresentationParameter::getnearlosslessDeviation

(

)

const [inline]

returns the desired NEAR parameter

Returns:

return desired NEAR-Parameter

virtual OFBool DJLSRepresentationParameter::operator==

(

const DcmRepresentationParameter &

arg

)

const [virtual]

compares an object to another DcmRepresentationParameter.

Implementation must make sure that classes are comparable.

Parameters:

arg	representation parameter to compare with

Returns:

true if equal, false otherwise.

Implements DcmRepresentationParameter.

OFBool DJLSRepresentationParameter::useLosslessProcess

(

)

const [inline]

returns true if lossless compression is desired

Returns:

true if lossless compression is desired
