Operation
There is a newer version of this page. You can find it here.
This is the mother class of any operation in general. Sum, Product and Quotient all derive from Operation.
An operation has elements (terms in a Sum, factors in a Product...), a neutral element (Item(1) for the Product and Quotient, Item(0) for the Sum), and a symbol ('+' for Sum, '×' for Product, 'like_a_fraction' or 'use_divide_symbol' for a Quotient)
| Fields | Methods (provided) | Methods (must be reimplemented) |
|---|---|---|
| element | get_element() | operator() |
| neutral | get_neutral() | |
| symbol | get_symbol() | |
| get_iteration_list() | ||
| set_element() | ||
| set_symbol() | ||
| reset_element() | ||
| __get_item__() | ||
| __set_item__() | ||
| is_expandable() | ||
| is_numeric() | ||
| is_literal() |
operator() has to be redefined in each instanciated Operation. It will make the operation between self and arg.
