Detailed Description

Abstract element base class, a technicality.

The element class of FieldAbstract. This element has no knowledge of the field to which it belongs. All operations and functions requiring knolwedge of the field, such as addition and other arithmetic operations, are supplied by the field and not the element class.

Constructor & Destructor Documentation

◆ ElementAbstract()

ElementAbstract ( void )

inlineprotected

Default Constructor.

Required by derived classes, but protected because this class should never be constructed by itself.

Member Function Documentation

◆ clone()

virtual ElementAbstract* clone ( void ) const

pure virtual

Virtual copy constructor.

Required because constructors cannot be virtual. Passes construction on to derived classes. Purely virtual.

Returns: pointer to new ElementAbstract object in dynamic memory.

Implemented in ElementEnvelope< Field >, and ElementEnvelope< Ring >.

◆ operator=()

virtual ElementAbstract& operator= ( const ElementAbstract & x )

pure virtual

Assignment operator.

Purely virtual.

Parameters

x	constant reference to ElementAbstract object

Returns: reference to self
