Constructor Detail

GTIngredientsAttribute

public GTIngredientsAttribute()

Construct an attribute in the default workspace with an empty string as its name. The object is added to the directory of the workspace. Increment the version number of the workspace.

GTIngredientsAttribute

public GTIngredientsAttribute(NamedObj container,
                              java.lang.String name)
                       throws IllegalActionException,
                              NameDuplicationException

Construct an attribute with the given name contained by the specified container. The container argument must not be null, or a NullPointerException will be thrown. This attribute 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 added to the directory of the workspace if the container is null. Increment the version of the workspace.

Parameters:

container - The container.

name - The name of this attribute.

Throws:

IllegalActionException - If the attribute is not of an acceptable class for the container, or if the name contains a period.

NameDuplicationException - If the name coincides with an attribute already in the container.

GTIngredientsAttribute

public GTIngredientsAttribute(Workspace workspace)

Construct an attribute in the specified workspace with an empty string as a name. The object is added to the directory of the workspace. Increment the version number of the workspace.

Parameters:

workspace - The workspace that will list the attribute.

Method Detail

clone

public java.lang.Object clone(Workspace workspace)
                       throws java.lang.CloneNotSupportedException

Clone the object into the specified workspace. The new object is not added to the directory of that workspace (you must do this yourself if you want it there). The result is an object with no container.

Overrides:

clone in class StringAttribute

Parameters:

workspace - The workspace for the cloned object.

Returns:

The new object.

Throws:

java.lang.CloneNotSupportedException - Not thrown in this base class

NamedObj.exportMoML(Writer, int, String), NamedObj.setDeferringChangeRequests(boolean)

getIngredientList

public GTIngredientList getIngredientList()
                                   throws MalformedStringException

Parse the expression of this attribute if necessary and return the up-to-date ingredient list contained in this attribute.

Returns:

The ingredient list.

Throws:

MalformedStringException - If error occurs while parsing the expression.

setExpression

public void setExpression(java.lang.String expression)
                   throws IllegalActionException

Set the expression of this attribute and defers parsing to the time when the ingredient list is obtained with getIngredientList() or when validate() is invoked.

Specified by:

setExpression in interface Settable

Overrides:

setExpression in class StringAttribute

Parameters:

expression - The new expression.

Throws:

IllegalActionException - If thrown by the superclass.

See Also:

StringAttribute.getExpression()

validate

public java.util.Collection<?> validate()
                                 throws IllegalActionException

Parse the expression if necessary.

Specified by:

validate in interface Settable

Overrides:

validate in class StringAttribute

Returns:

Always null.

Throws:

IllegalActionException - If error occurs while parsing the expression.
