Constructor Detail

AbstractTextAttribute

public AbstractTextAttribute(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. 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.

attributeChanged

public void attributeChanged(Attribute attribute)
                      throws IllegalActionException

React to a changes in the attributes by changing the icon.

Overrides:

attributeChanged in class NamedObj

Parameters:

attribute - The attribute that changed.

Throws:

IllegalActionException - If the change is not acceptable to this container (should not be thrown).

clone

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

Clone the object into the specified workspace.

Overrides:

clone in class Attribute

Parameters:

workspace - The workspace for the new object.

Returns:

A new AbstractTextAttribute.

Throws:

java.lang.CloneNotSupportedException - If any of the attributes cannot be cloned.
