Constructor & Destructor Documentation

Power::Power	(	Node *	one,
		Node *	two,
		Node *	parent,
		bool	neg = `false`,
		Node::Select	s = `Node::Select::NONE`
	)

inline

Constructor for Power class.

Parameters

one	First expression.
two	Second expression.
parent	Parent node.
neg	If true, node is negative.
s	Selection state of node.

Power::Power	(	EqnXMLParser &	in,
		Node *	parent
	)

inline

XML constructor for Divide class. Read in XML for Divide class.

Parameters

in	XML input stream.
parent	Parent node object.

Power::~Power ( )

inline

Abstract base class needs virtual destructor.

Member Function Documentation

void Power::calcOrig	(	UI::Graphics &	gc,
		int	x,
		int	y
	)

privatevirtual

Calculate origin of this node offset from the point (x,y) given it.

Parameters

gc	Graphics context.
x	Horizontal origin.
y	Vertical origin.

Implements Node.

Node::Frame Power::calcSize ( UI::Graphics & gc )

privatevirtual

void Power::normalize ( )

virtual

Refactor subtree to a standard form. For Power class, replace (ab)^2(c^d)^2 with (a^2)(b^2)c^(2d)

Reimplemented from Node.

bool Power::simplify ( )

virtual

Attempt to algebraically simplify the subtree this node is the root.

Returns: True, if subtree was changed.

Reimplemented from Node.

bool Power::simplify ( NodeVector & factors )

static

Static helper function for simplifying Power expressions. Simplify each node in the vector against every other node.

Returns: True, if node vector was changed.

bool Power::simplify	(	NodeVector::iterator	a,

	)

staticprivate

Static helper function for simplifying Power expressions. If both iterators point to a Power object, see if they can be combined.

Parameters

a	First iterator.
b	Second iterator.

Returns: True, if node vector was changed.
