	Apply the inverse Maps to the point(s) target_point. The returned std::optional is invalid if the map is not invertible at target_point, or if target_point can be easily determined to not make sense for the map. An example of the latter is passing a point with a negative value of z into a positive-z Wedge<3> inverse map. The inverse function is only callable with doubles because the inverse might fail if called for a point out of range, and it is unclear what should happen if the inverse were to succeed for some points in a DataVector but fail for other points.

Member Function Documentation

function_of_time_names()

template<typename SourceFrame , typename TargetFrame , size_t Dim>

virtual const std::unordered_set< std::string > & domain::CoordinateMapBase< SourceFrame, TargetFrame, Dim >::function_of_time_names ( ) const

pure virtual

Get a set of all FunctionOfTime names used in this mapping.

Implemented in domain::CoordinateMap< SourceFrame, TargetFrame, Maps >.

get_to_grid_frame()

template<typename SourceFrame , typename TargetFrame , size_t Dim>

virtual std::unique_ptr< CoordinateMapBase< SourceFrame, Frame::Grid, Dim > > domain::CoordinateMapBase< SourceFrame, TargetFrame, Dim >::get_to_grid_frame ( ) const

pure virtual

Retrieve the same map but going from SourceFrame to Frame::Grid.

This functionality is needed when composing time-dependent maps with time-independent maps, where the target frame of the time-independent map is Frame::Grid.

Implemented in domain::CoordinateMap< SourceFrame, TargetFrame, Maps >.

inv_jacobian_is_time_dependent()

template<typename SourceFrame , typename TargetFrame , size_t Dim>

virtual bool domain::CoordinateMapBase< SourceFrame, TargetFrame, Dim >::inv_jacobian_is_time_dependent ( ) const

pure virtual

Returns true if the inverse Jacobian depends on time.

Implemented in domain::CoordinateMap< SourceFrame, TargetFrame, Maps >.

is_identity()

template<typename SourceFrame , typename TargetFrame , size_t Dim>

virtual bool domain::CoordinateMapBase< SourceFrame, TargetFrame, Dim >::is_identity ( ) const

pure virtual

Returns true if the map is the identity.

Implemented in domain::CoordinateMap< SourceFrame, TargetFrame, Maps >.

jacobian_is_time_dependent()

template<typename SourceFrame , typename TargetFrame , size_t Dim>

virtual bool domain::CoordinateMapBase< SourceFrame, TargetFrame, Dim >::jacobian_is_time_dependent ( ) const

pure virtual

Returns true if the Jacobian depends on time.

Implemented in domain::CoordinateMap< SourceFrame, TargetFrame, Maps >.
