template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>

AbstractTetrahedralElement< ELEMENT_DIM, SPACE_DIM >::AbstractTetrahedralElement	(	unsigned	index,
		const std::vector< Node< SPACE_DIM > * > &	rNodes
	)

Constructor which takes in a vector of nodes.

Parameters:

index	the index of the element in the mesh
rNodes	the nodes owned by the element

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>

AbstractTetrahedralElement< ELEMENT_DIM, SPACE_DIM >::AbstractTetrahedralElement ( unsigned index = INDEX_IS_NOT_USED )

Default constructor, which doesn't fill in any nodes. The nodes must be added later.

Parameters:

index the index of the element in the mesh (defaults to INDEX_IS_NOT_USED)

Definition at line 105 of file AbstractTetrahedralElement.cpp.

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>

virtual AbstractTetrahedralElement< ELEMENT_DIM, SPACE_DIM >::~AbstractTetrahedralElement ( ) [inline, virtual]

Virtual destructor, since this class has virtual methods.
