Detailed Description

Base class for nodes represent an operator that contains two expressions. Not all pure virtual functions are overriden so is an abstract base class.

Constructor & Destructor Documentation

Binary::Binary	(	char	op,
		Node *	one,
		Node *	two,
		Node *	parent,
		bool	neg,
		Node::Select	s
	)

inline

Constructor for Binary class.

Parameters

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

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

XML constructor for Binary class. Read in XML that is common for all nodes that have a Binary base class.

Parameters

in	XML input stream.
parent	Parent node object.

virtual Binary::~Binary ( )

inlinevirtual

Virtual desctructor. Abstract base class needs virtual desctructor.

Member Function Documentation

Node* Binary::downLeft ( )

inlineprivatevirtual

Get left node. For Binary class is its first expression.

Returns: Left node.

Reimplemented from Node.

Node* Binary::downRight ( )

inlineprivatevirtual

Get right node. For Binary class is its second expression.

Returns: Right node.

Reimplemented from Node.

Node * Binary::findNode	(	int	x,
		int	y
	)

virtual

Rescursive search to find deepest node at point (x,y).

Parameters

x	horizontal coordinate.
y	vertical coordinate.

Returns: Deepest node at point (x,y).

Reimplemented from Node.

Node * Binary::findNode ( const Box & b )

virtual

Recursive function to return first node from a top to bottom search whose frame is inside Box b.

Parameters

b	Bounding box.

Returns: Top node inside bounding box.

Reimplemented from Node.

ExpressionPtr Binary::getFirstExpression ( )

Get first expression of this node.

Returns: First expression.

Node* Binary::getLeftSibling ( Node * node )

inlineprivatevirtual

Left sibiling of given node. If node given is right node, return left node.

Parameters

node	Reference node.

Returns: Left sibiling or null.

Reimplemented from Node.

Node* Binary::getRightSibling ( Node * node )

inlineprivatevirtual

Right sibiling of given node. If node given is left node, return right node.

Parameters

node	Reference node.

Returns: Right sibiling or null.

Reimplemented from Node.

ExpressionPtr Binary::getSecondExpression ( )

Get second expression of this node.

Returns: Second expression.

bool Binary::isLeaf ( ) const

inlinevirtual

Override for isLeaf virtual function.

Returns: False, this node has child nodes.

Reimplemented from Node.

int Binary::numFactors ( ) const

inlinevirtual

Get number of factor in this subtree.

Returns: Return number of factors in both expressions.

Reimplemented from Node.

Node * Binary::parse	(	Parser &	p,
		Node *	one,
		Node *	parent
	)

static

Static helper function to parse Binary class.

Parameters

p	Parser object pointing to operator.
one	First expression already parsed.
parent	Parent node.

Returns: Binary object or null if operator not binary.

std::string Binary::toString ( ) const

inlinevirtual

Get string representation of Binary object. Simply first node, operator, second node.

Returns: String representation of Binary object.

Implements Node.

void Binary::xml_out ( XML::Stream & xml ) const

privatevirtual

Output XML of this node.

Parameters

xml	XML output stream.

Implements Node.
