Detailed Description

abstract base class for codec representation parameter sets.

A codec parameter set subclass is implemented for each codec and passed to the codec by the encode() and decode() routines. It is supposed to contain data that may vary between compressed image representations using the same transfer syntax, for example the quality factor or compression factor for lossy compression.

Member Function Documentation

virtual const char* DcmRepresentationParameter::className

(

)

const [pure virtual]

returns the class name as string.

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

Implemented in DJLSRepresentationParameter, DJ_RPLossless, DJ_RPLossy, and DcmRLERepresentationParameter.

virtual DcmRepresentationParameter* DcmRepresentationParameter::clone

(

)

const [pure virtual]

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

Returns:

copy of this object

Implemented in DJLSRepresentationParameter, DJ_RPLossless, DJ_RPLossy, and DcmRLERepresentationParameter.

virtual OFBool DcmRepresentationParameter::operator==

(

const DcmRepresentationParameter &

arg

)

const [pure 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.

Implemented in DJLSRepresentationParameter, DJ_RPLossless, DJ_RPLossy, and DcmRLERepresentationParameter.
