    • Constructor Detail

      • TableauParameter

        public TableauParameter​(NamedObj container,
                        java.lang.String name)
                 throws IllegalActionException,
                        NameDuplicationException
        Construct a parameter with the given name contained by the specified entity. The container argument must not be null, or a NullPointerException will be thrown. This parameter will use the workspace of the container for synchronization and version counts. If the name argument is null, then the name is set to the empty string. The object is not added to the list of objects in the workspace unless the container is null. Increment the version of the workspace.
        Parameters:
        container - The container.
        name - The name of the parameter.
        Throws:
        IllegalActionException - If the parameter is not of an acceptable class for the container.
        NameDuplicationException - If the name coincides with a parameter already in the container.

      • clone

        public java.lang.Object clone​(Workspace workspace)
                       throws java.lang.CloneNotSupportedException
        Clone the variable. This creates a new variable containing the same token (if the value was set with setToken()) or the same (unevaluated) expression, if the expression was set with setExpression(). The list of variables added to the scope is not cloned; i.e., the clone has an empty scope. The clone has the same static type constraints (those given by setTypeEquals() and setTypeAtMost()), but none of the dynamic type constraints (those relative to other variables).
        Overrides:
        clone in class Parameter
        Parameters:
        workspace - The workspace in which to place the cloned variable.
        Returns:
        The cloned variable.
        Throws:
        java.lang.CloneNotSupportedException - Not thrown in this base class.

      • setContainer

        public void setContainer​(NamedObj container)
                  throws IllegalActionException,
                         NameDuplicationException
        Specify the container, and add this variable to the list of attributes in the container. If this variable already has a container, remove this variable from the attribute list of the current container first. Otherwise, remove it from the directory of the workspace, if it is there. If the specified container is null, remove this variable from the list of attributes of the current container. If the specified container already contains an attribute with the same name, then throw an exception and do not make any changes. Similarly, if the container is not in the same workspace as this variable, throw an exception. If this variable is already contained by the specified container, do nothing.

        If this method results in a change of container (which it usually does), then remove this variable from the scope of any scope dependent of this variable.

        This method is write-synchronized on the workspace and increments its version number.

        Overrides:
        setContainer in class Variable
        Parameters:
        container - The proposed container of this variable.
        Throws:
        IllegalActionException - If the container will not accept a variable as its attribute, or this variable and the container are not in the same workspace, or the proposed container would result in recursive containment.
        NameDuplicationException - If the container already has an attribute with the name of this variable.

        Attribute.getContainer()

      • setExpression

        public void setExpression​(java.lang.String expression)
        Do nothing because a tableau cannot be specified with an exception.
        Specified by:
        setExpression in interface Settable
        Overrides:
        setExpression in class Variable
        Parameters:
        expression - The expression.
