AbstractStateSpaceSimulator
public AbstractStateSpaceSimulator(CompositeEntity container, java.lang.String name) throws NameDuplicationException, IllegalActionException
Construct the composite actor with a name and a container. This constructor creates the ports, parameters, and the icon.- Parameters:
container
- The container.name
- The name.- Throws:
NameDuplicationException
- If another entity already had this name.IllegalActionException
- If there was an internal problem.
-
AbstractStateSpaceSimulator
public AbstractStateSpaceSimulator(Workspace workspace) throws IllegalActionException, NameDuplicationException
Construct an actor in the specified workspace with no container and an empty string as a name. You can then change the name with setName(). If the workspace argument is null, then use the default workspace.- Parameters:
workspace
- The workspace that will list the actor.- Throws:
IllegalActionException
- If the name has a period in it, or the director is not compatible with the specified container.NameDuplicationException
- If the container already contains an entity with the specified name.
-
-
Method Detail
-
attributeChanged
public void attributeChanged(Attribute attribute) throws IllegalActionException
If the argument is any parameter other than stateVariableNames t, or any parameter matching an input port, then request reinitialization.- Overrides:
attributeChanged
in classTypedCompositeActor
- Parameters:
attribute
- The attribute that changed.- Throws:
IllegalActionException
- If the numerator and the denominator matrix is not a row vector.
-
fire
public void fire() throws IllegalActionException
Override the base class to first set the value of the parameter t to match current time, then to set the local parameters that mirror input values, and then to fire the contained actors.- Specified by:
fire
in interfaceExecutable
- Overrides:
fire
in classCompositeActor
- Throws:
IllegalActionException
- If there is no director, or if the director's fire() method throws it, or if the actor is not opaque.
-
preinitialize
public void preinitialize() throws IllegalActionException
Create the model inside from the parameter values. This method gets write access on the workspace.- Specified by:
preinitialize
in interfaceInitializable
- Overrides:
preinitialize
in classCompositeActor
- Throws:
IllegalActionException
- If there is no director, or if any contained actors throws it in its preinitialize() method.
-
wrapup
public void wrapup() throws IllegalActionException
Description copied from class:CompositeActor
If this actor is opaque, then invoke the wrapup() method of the local director. This method is read-synchronized on the workspace.- Specified by:
wrapup
in interfaceInitializable
- Overrides:
wrapup
in classCompositeActor
- Throws:
IllegalActionException
- If there is no director, or if the director's wrapup() method throws it, or if this actor is not opaque.
-
_checkParameters
protected abstract void _checkParameters() throws IllegalActionException
Check the dimensions of all parameters and ports.- Throws:
IllegalActionException
- If the dimensions are illegal.
-
getUserDefinedParameterExpression
protected java.lang.String getUserDefinedParameterExpression(java.lang.String parameterName) throws IllegalActionException
Return the expression for a user-defined parameter.- Parameters:
parameterName
- Name of parameter- Returns:
- parameter expression
- Throws:
IllegalActionException
-
getUserDefinedParameter
protected abstract Parameter getUserDefinedParameter(java.lang.String parameterName) throws IllegalActionException
Return the Parameter that is part of a state space model.- Parameters:
parameterName
- Name of parameter- Returns:
- Parameter object
- Throws:
IllegalActionException
