Detailed Description

This class is used to create a usually threadsafe resolver to evaluate forces. It binds most of the data to cut the number of parameter evaluations needed, caching where sensible. Each thread should have its own resolver for thread-local caches, so use the copy() method for each thread.

	)			[virtual]

Reimplemented in SIM_ForceResolverGeneric.

virtual bool SIM_ForceResolver::hasJacobian

(

)

const [inline, virtual]

Whether the getForceJacobian returns non-zero values. The default implementation is to always return a 0 jacobian, hence hasJacobian of false.

Reimplemented in SIM_ForceResolverGeneric.

const SIM_ForceResolver &

src

)

[virtual]

virtual bool SIM_ForceResolver::threadsafe

(

)

const [virtual]

Defaults to the resolver being threadsafe provided all of the noise resolvers are threadsafe.

Reimplemented in SIM_ForceResolverGeneric.
