    Entries of indices object passed to calculateAdditive to be passed to added derivation


Derived Types

type, public, extends(Derivation) ::  AdditiveDerivation

Composite derivation class containing a number of calculation rules applied additively. All derivations must return same length array

Components

Type Visibility Attributes Name Initial
logical, public :: userDefined = .false.

True only if user explicitly sets it to true
type(DerivationContainer), private, allocatable, dimension(:) :: derivs

Derivation whose results to be added
type(IntArray), private, allocatable, dimension(:) :: derivIndices

Subset of indices vector passed to each derivation
integer(kind=ik), private :: numAddedDerivations

Counter for keeping track of added derivations
integer(kind=ik), private :: expectedNumIndices

Expected size of indices array - for errorChecking
real(kind=rk), private :: resultPower

Optional power to which the result is raised = default 1
real(kind=rk), private, allocatable, dimension(:) :: linearCoefficients

Additive linear combination coefficients associated with each derivation. Defaults to ones.
