◆ computePolarized()

std::complex< double > PARTONS::DVCSCFFDispersionRelation::computePolarized ( )

privatevirtual

Method to compute some CFFs.

Can be implemented and used in child class, if needed.

Returns: Complex result.

Reimplemented from PARTONS::DVCSConvolCoeffFunctionModule.

◆ configure()

void PARTONS::DVCSCFFDispersionRelation::configure ( const ElemUtils::Parameters & parameters )

virtual

Provides a generic method to configure all types of modules by passing a Parameters object.

Parameters class represents a list of couples key/value (see Parameters class documentation for more info).

Parameters

parameters ElemUtils::Parameters object.

Reimplemented from PARTONS::DVCSConvolCoeffFunctionModule.

private

Initialize functors.

◆ initModule()

void PARTONS::DVCSCFFDispersionRelation::initModule ( )

protectedvirtual

Pure virtual function that provides skeleton for module initialization.

virtual

Method used in automation to prepare all the modules used by this current module and configure them recursively.

The recursion is linked to the imbrication in XML files.
Can be implemented in the child class if it needs modules not needed by the parent class. But there must be first a call to the parent method.

subModulesData Data used to retrieve the needed modules and their configuration.

Reimplemented from PARTONS::DVCSConvolCoeffFunctionModule.

◆ resolveObjectDependencies()

void PARTONS::DVCSCFFDispersionRelation::resolveObjectDependencies ( )

virtual

Because of the initialization step order of the program, objects are registered in a total random order and some objects depend on others.

To avoid the problem of pointer resolution order, this method is called by the BaseObjectRegistery after all objects are well registered in it. See BaseObjectRegistry class documentation for more details.

Reimplemented from PARTONS::DVCSConvolCoeffFunctionModule.
