Constructor & Destructor Documentation

def core.base_calculus.Operation.__init__

(

self

)

Constructor.

Warning:

Operation objects are not really usable

Returns:

An "instance" of Operation

Reimplemented from core.root_calculus.Exponented.

Reimplemented in core.base_calculus.CommutativeOperation.

Definition at line 1872 of file base_calculus.py.

References core.base_calculus.Operation._element, core.base_calculus.Operation._neutral, and core.base_calculus.Operation._symbol.

Referenced by core.calculus.Equation.__init__(), and core.root_calculus.Value.substitute().

Member Function Documentation

def core.base_calculus.Operation.__hash__

(

self

)

Makes any Operation hashable (so, usable as dictionnary keys)

Warning:

Seems that subclasses that redefine __eq__() are forgetting __hash__()

Reimplemented in core.base_calculus.Product.

Definition at line 1994 of file base_calculus.py.

def core.base_calculus.Operation.is_expandable

(

self

)

True if the Operation contains any Expandable.

Returns:

True|False

Reimplemented in core.base_calculus.Expandable.

Definition at line 2032 of file base_calculus.py.

def core.base_calculus.Operation.set_element	(		self,
			n,
			arg
	)

Parameters:

n	: number of the element to set
arg	: the object to put as n-th element
