## Detailed Description

This class implements a nonbonded interaction between pairs of particles typically used along with AmoebaGeneralizedKirkwoodForce as part of an implicit solvent model.

To use it, create an AmoebaWcaDispersionForce object then call addParticle() once for each particle. After a particle has been added, you can modify its force field parameters by calling setParticleParameters(). This will have no effect on Contexts that already exist unless you call updateParametersInContext().

def updateParametersInContext | ( |  | self,
|  |  | args |
| ) |  |  |

updateParametersInContext(AmoebaWcaDispersionForce self, Context context)

Update the per-particle parameters in a Context to match those stored in this Force object. This method provides an efficient method to update certain parameters in an existing Context without needing to reinitialize it. Simply call setParticleParameters() to modify this object's parameters, then call updateParametersInState() to copy them over to the Context.

The only information this method updates is the values of per-particle parameters. All other aspects of the Force are unaffected and can only be changed by reinitializing the Context.
