AbstractSettableAttribute
ptolemy.kernel.util.AbstractSettableAttribute

This is an abstract base class for attributes that implement the Settable interface. In particular, it provides a default implementation of the getDefaultExpression() method. If this object is derived from another, then the default value is obtained from that other. Otherwise, the default value is the first value set using setExpression().
