AdjointsManagement
Policies for management of the tape's interal adjoints.
Definition: tapeParameters.hpp:98
@ Automatic
Manage internal adjoints automatically, including locking, bounds checking, and resizing.
Allow for a direct access to the gradient information computed by the tape.

void setGradient(Identifier const &identifier, Gradient const &gradient, AdjointsManagement adjointsManagement=AdjointsManagement::Automatic)
Set the gradient.
Gradient & gradient(Identifier const &identifier, AdjointsManagement adjointsManagement=AdjointsManagement::Automatic)
Reference access to gradient.
Gradient const & gradient(Identifier const &identifier, AdjointsManagement adjointsManagement=AdjointsManagement::Automatic) const
Constant reference access to gradient.
Gradient const & getGradient(Identifier const &identifier, AdjointsManagement adjointsManagement=AdjointsManagement::Automatic) const
Set the gradient.
