Detailed Description

Used to create a PLMD::Action that has some scalar or vectorial output that may or may not have some derivatives. This is used for PLMD::Bias, PLMD::Colvar and PLMD::Function

The vast majority of the PLMD::Action objects that are implemented in plumed calculate some quantity or a set of quantities. This could be the value of a CV, the value of a function or the potential due to a bias. PLMD::ActionWithValue provides the functionality for storing these quantities and (in tandem with PLMD::ActionWithArguments) the functionality for passing quantities between PLMD::Actions. When you are deciding what quantities your new PLMD::Action will need to store using PLMD::ActionWithValue you must ask yourself the following two questions:

Do I need to differentiate my output quantities
Is my PLMD::Action calculating a single thing or does the output have multiple components

If the answer to the first of these questions is yes then you must setup your values you using either PLMD::ActionWithValue::addValueWithDerivatives() or PLMD::ActionWithValue::addComponentWithDerivatives. If the answer is no you can set up values using PLMD::ActionWithValue::addValue() or PLMD::ActionWithValue::addComponent(). The precise routine you use to setup your values will depend on your answer to the second question. As you are probably aware if the output of your PLMD::Action is a single quantity you can reference that quantity in the input file using the label of the PLMD::Action it was calculated in. If your action outputs only one quantity we call that quantity the value of the Action. To set the value and get pointers to it you should use the set of routines that have the word value in the name . If, by contrast, your PLMD::Action calculates multiple quantities then these quantities are referenced in input using the label.component syntax. We refer to these multiple quantities the components of the PLMD::Action. Perhaps unsurprisingly, when you manipulate the components of an PLMD::Action you should use the routines with the word component in the name.
