Detailed Description

Enumeration and functions to specify a model for polymer chains.

PSCF allows the use of either a continuous "thread" or a discrete "bead" model for chain conformations. The PolymerModel::Type enumeration type has two allowed values of PolymerModel::Thread and PolymerModel::Bead that identify these two models.

Functions defined in the PolymerModel namespace can be used to set and query a globally accessible pseudo private variable of type PolymerModel::Type that specifies which of these two models is being used throughout a program. This model type variable is initialized to PolymerModel::Thread by default. In PSCF programs that can support either thread or bead models, a choice of model should be set in the early stages of program execution and not changed again before the program terminates.

Function Documentation

◆ setModel()

void Pscf::PolymerModel::setModel ( PolymerModel::Type model )

Set the global polymer model enumeration value.

Parameters

model polymer model type enumeration value

Definition at line 45 of file PolymerModel.cpp.

References model(), and UTIL_CHECK.

◆ lock()

void Pscf::PolymerModel::lock ( )

Make the polymer model immutable.

Locking the polymer model is irreversible - there is no unlock function.

Advice: Lock the model shortly after it is set in the execution path of the main program for PSCF executable programs. Do not lock the model in unit tests, so that a unit test runner can run different tests that test the thread and bead model.

◆ isLocked()

bool Pscf::PolymerModel::isLocked ( )

Has the model type been locked (i.e., made immutable) ?

◆ nSet()

int Pscf::PolymerModel::nSet ( )

How many times has setModel been called?

This returns a counter that is initialized to zero, and is incremented every times setModel is invoked. It can be used confirm that polymer model was not changed within a section of code..
