Classes
class	ROL::ElementwiseVector< Real >
	Intermediate abstract class which does not require users implements plus, set, scale, axpy, norm, dot, or zero if they implement the three elementwise functions: applyUnary, applyBinary, and reduce. More...
class	ROL::MultiVector< Real >
	Provides a container and operations on multiple ROL vectors for use with other Trilinos packages which require multivectors. More...
class	ROL::MultiVectorDefault< Real >
	Default implementation of the ROL::MultiVector container class. More...
class	ROL::PartitionedVector< Real >
	Defines the linear algebra of vector space on a generic partitioned vector. More...

class	ROL::Vector_SimOpt< Real >
	Defines the linear algebra or vector space interface for simulation-based optimization. More...
class	ROL::SimulatedVector< Real >
	Defines the linear algebra of a vector space on a generic partitioned vector where the individual vectors are distributed in batches defined by ROL::BatchManager. This is a batch-distributed version of ROL::PartitionedVector. More...
