State Wrapper

State Wrapper

Description

The State Wrapper concept describes the way odeint creates temporary state objects to store intermediate results within the stepper's do_step methods.

Notation

State: A type that is the state_type of the ODE
WrappedState: A type that is a model of State Wrapper for the state type State.
x: Object of type State
w: Object of type WrappedState

Valid Expressions

Name	Expression	Type	Semantics
Get resizeability	`is_resizeable< State >`	`boost::false_type` or `boost::true_type`	Returns `boost::true_type` if the `State` is resizeable, `boost::false_type` otherwise.
Create `WrappedState` type	`state_wrapper< State >`	`WrappedState`	Creates the type for a `WrappedState` for the state type `State`
Constructor	`WrappedState()`	`WrappedState`	Constructs a state wrapper with an empty state
Copy Constructor	`WrappedState( w )`	`WrappedState`	Constructs a state wrapper with a state of the same size as the state in `w`
Get state	`w.m_v`	`State`	Returns the `State` object of this state wrapper.
