Constructor & Destructor Documentation

madara::expression::CompositeSquareRootNode::CompositeSquareRootNode	(	logger::Logger &	logger,
		ComponentNode *	right
	)

Constructor.

Parameters

logger	the logger to use for printing
right	right expression

Definition at line 16 of file CompositeSquareRootNode.cpp.

madara::expression::CompositeSquareRootNode::~CompositeSquareRootNode ( void )

virtual

Destructor.

Definition at line 23 of file CompositeSquareRootNode.cpp.

Member Function Documentation

void madara::expression::CompositeSquareRootNode::accept ( Visitor & visitor ) const

virtual

Accepts a visitor subclassed from the Visitor class.

Parameters

visitor visitor instance to use

Reimplemented from madara::expression::ComponentNode.

Definition at line 82 of file CompositeSquareRootNode.cpp.

madara::knowledge::KnowledgeRecord madara::expression::CompositeSquareRootNode::evaluate ( const madara::knowledge::KnowledgeUpdateSettings & settings )

virtual

Evaluates the node.

Evaluates the node and its children.

Parameters

settings settings for evaluating the node

Returns: negation of the right expression

This does not prune any of the expression tree, and is much faster than the prune function

Implements madara::expression::ComponentNode.

Definition at line 68 of file CompositeSquareRootNode.cpp.

madara::knowledge::KnowledgeRecord madara::expression::CompositeSquareRootNode::item ( void ) const

virtual

Returns the printable character of the node.

Returns: value of the node

Reimplemented from madara::expression::ComponentNode.

Definition at line 28 of file CompositeSquareRootNode.cpp.

madara::expression::ComponentNode * madara::expression::ComponentNode::left ( void ) const

virtualinherited

Returns the left expression.

Returns: a pointer to the left expression

Reimplemented in madara::expression::CompositeBinaryNode.

Definition at line 34 of file ComponentNode.cpp.

madara::knowledge::KnowledgeRecord madara::expression::CompositeSquareRootNode::prune ( bool & can_change )

virtual

Prunes the expression tree of unnecessary nodes.

Prune the tree of unnecessary nodes.

Parameters

can_change set to true if variable nodes are contained

Returns: negation of the right expression

Returns evaluation of the node and sets can_change appropriately. if this node can be changed, that means it shouldn't be pruned.

Implements madara::expression::ComponentNode.

Definition at line 37 of file CompositeSquareRootNode.cpp.

madara::expression::ComponentNode * madara::expression::CompositeUnaryNode::right ( void ) const

virtualinherited

Returns the right expression.

Returns: a pointer to the right expression

Reimplemented from madara::expression::ComponentNode.

Definition at line 24 of file CompositeUnaryNode.cpp.

void madara::expression::ComponentNode::set_logger ( logger::Logger & logger )

inherited

Sets the logger for printing errors and debugging info.

Parameters

logger the logger to use

Definition at line 53 of file ComponentNode.cpp.
