Methods in ptolemy.graph that return Element

Modifier and Type	Method and Description
Element	ElementList.element(java.lang.Object weight) Return an element in this list that has a specified weight.

Methods in ptolemy.graph with parameters of type Element

Modifier and Type	Method and Description
boolean	ElementList.cancelWeight(Element element) Disassociate the given element from its weight information.
boolean	ElementList.changeWeight(Element element) Given an element in this list, check if the weight has changed (since the element was added to the graph or was last validated, whichever is more recent), and if so, change the current mapping of a weight to the element or remove the element from the set of unweighted elements.
static java.lang.String	GraphException.elementDump(Element element, Graph graph) Return a dump of a graph element and the container graph suitable to be appended to an error message.
void	ElementList.registerWeight(Element element) Associate a graph element to its weight given the relevant mapping of weights to elements, and the set of unweighted elements of the same type (nodes or edges).
boolean	ElementList.remove(Element element) Remove an element from this list if it exists in the list.
boolean	ElementList.validateWeight(Element element, java.lang.Object oldWeight) Validate the weight of a given graph element, given the previous weight of that element.
