inherited

Specify that this Action depends on another one.

◆ apply()

inlineoverridevirtual

Apply an Action.

This method is called one time per step. The set of all Actions is applied in backward order.

Implements PLMD::Action.

◆ beforeUpdate()

virtual void PLMD::Action::beforeUpdate ( )

inlinevirtualinherited

Before Update.

This is a special method that is called just before the update() method. It can be used by actions that want to do something irrespectively of the fact that update() is active or not. In other words, this is always called, even when action is not active.

Reimplemented in PLMD::generic::UpdateIf.

◆ calculate()

void PLMD::generic::RandomExchanges::calculate ( )

inlineoverridevirtual

Calculate an Action.

This method is called one or more times per step. The set of all Actions is calculated in forward order.

Implements PLMD::Action.

◆ calculateFromPDB()

void PLMD::Action::calculateFromPDB ( const PDB & pdb )

inherited

Calculate the action given a pdb file as input.

This is used to initialize things like distance from a point in CV map space given a pdb as an input file

◆ calculateNumericalDerivatives()

void PLMD::Action::calculateNumericalDerivatives ( ActionWithValue * a = NULL )

virtualinherited

Perform calculation using numerical derivatives N.B.

only pass an ActionWithValue to this routine if you know exactly what you are doing.
