Constructs the function using the initial time, initial values, derivative and expiration time. If rotation is true, the function will be converted to a quaternion before it is output as used by the Rotation map. | |

Updates the function to the next global time step. The updated_value_and_derivative argument needs to be a DataVector of size 2, with the zeroth element holding the function's value and the first element holding its derivative. If rotation_ is set to true, this corresponds to the angle and the angular velocity for a rotation about the z-axis. More... | |

bool | operator== (const IntegratedFunctionOfTime &lhs, const IntegratedFunctionOfTime &rhs) |
A function that is integrated manually.
This function only works with global time steppers that have strictly positively increasing substeps. When evaluated at this global time step, it returns the function and first derivative at that time step. It therefore needs to be updated every time step with its current values.

The first expiration time after time
.
For non-updatable functions, this returns infinity. For updatable functions, the first expiration time after time
is found by determining the update immediately before time
. The expiration time of this update is what is returned. If time
happens to be an update itself, then the expiration of that update is returned.

Updates the function to the next global time step. The updated_value_and_derivative
argument needs to be a DataVector of size 2, with the zeroth element holding the function's value and the first element holding its derivative. If rotation_
is set to true, this corresponds to the angle and the angular velocity for a rotation about the z-axis.
