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().
