Detailed Description

template<typename ValueTypeOperator, typename ValueTypeOperand, utils::MemorySpace memorySpace, size_type dim>
class dftefe::basis::CFEOverlapOperatorContext< ValueTypeOperator, ValueTypeOperand, memorySpace, dim >

A derived class of linearAlgebra::OperatorContext to encapsulate the action of a discrete operator on vectors, matrices, etc.

Template Parameters

ValueTypeOperator	The datatype (float, double, complex<double>, etc.) for the underlying operator. Ususlly ValueTypeBasisData in FE basis
ValueTypeOperand	The datatype (float, double, complex<double>, etc.) of the vector, matrices, etc. on which the operator will act. Ususlly ValueTypeBasisCoeff in FE basis
memorySpace	The memory space (HOST, DEVICE, HOST_PINNED, etc.) in which the data of the operator and its operands reside
