Constructor Detail

BaseMultipleMethodsActor

public BaseMultipleMethodsActor(CompositeEntity container,
                                java.lang.String name)
                         throws IllegalActionException,
                                NameDuplicationException

Create a new instance of an ASCETClassActor with the given name and container.

Parameters:

container - The model in which the new actor will be contained.

name - The name of the new actor

Throws:

IllegalActionException - If the new actor cannot be created.

NameDuplicationException - If there is already a NamedObj with the same name in the container model.

Method Detail

getDefaultFireMethodName

public java.lang.String getDefaultFireMethodName()

Return the name of the default fire method for this actor.

Specified by:

getDefaultFireMethodName in interface MultipleFireMethodsInterface

Returns:

The string name of the default fire method for the actor. If the actor does not have multiple fire methods, return null.

getFireMethodNames

public java.util.List<java.lang.String> getFireMethodNames()

Return the list of strings that represent the names of all the fire methods the actor has.

Specified by:

getFireMethodNames in interface MultipleFireMethodsInterface

Returns:

The list of fire method names strings.

getMethodInputPortList

public java.util.List<IOPort> getMethodInputPortList(java.lang.String methodName)

Return the list of input ports associated with the given method name. If the method has no input ports, return an empty list. If the actor does not have multiple methods, return null.

Specified by:

getMethodInputPortList in interface MultipleFireMethodsInterface

Parameters:

methodName - The specified method name.

Returns:

The list of input ports associated with the method name.

getMethodOutputPort

public IOPort getMethodOutputPort(java.lang.String methodName)

Return the output port associated with the given method name, if there is one. If the method does not have any outputs, or the actor does not have multiple fire methods, return null

Specified by:

getMethodOutputPort in interface MultipleFireMethodsInterface

Parameters:

methodName - The specified name of the method.

Returns:

The output port associated with this method, or null is there is none.

numFireMethods

public int numFireMethods()

Return the number of fire methods the actor has.

Specified by:

numFireMethods in interface MultipleFireMethodsInterface

Returns:

the number of fire methods the actor has, which should be at least one.

setFireMethod

public void setFireMethod(java.lang.String methodName)
                   throws IllegalActionException

Set the fire method to the method that matches the specified string name.

Specified by:

setFireMethod in interface MultipleFireMethodsInterface

Parameters:

methodName - The name of the method to be used.

Throws:

IllegalActionException - If the specified fire method cannot be found in the actor.

_addFireMethod

protected void _addFireMethod(java.lang.String methodName,
                              IOPort outputPort,
                              java.util.List<IOPort> inputPorts)
                       throws IllegalActionException,
                              NameDuplicationException

Add a fire method for this actor with the specified name. A fire method can optionally be associated with one output port and a list of input ports. No two methods can be associated with the same input port or output port. And no two methods can have the same name.

Parameters:

methodName - The name of the fire method to be added.

outputPort - The output port associated with this method, or null if there is none.

inputPorts - The list of input ports associated with this method, or null if there are none.

Throws:

IllegalActionException - If a the method specifies an output port or input ports already associated with another fire method.

NameDuplicationException - If there is already another method with the same name specified for this actor.
