Constructor & Destructor Documentation
|
Element::Element (
|
int tag,
|
|
int classTag )
|
|
|
|
To construct an element whose unique integer among elements in the domain is given by {tag}, and whose class identifier is given by {classTag}. Both of these integers are passed to the DomainComponent constructor.
Definition at line 50 of file Element.cpp. |
|
Element::~Element (
|
) [virtual]
|
|
|
|
The destructor. Declared as virtual to allow subclass destructors to be invoked.
