Detailed Description

This class represents a node in the abstract syntax tree representation of an expression.

Each node is defined by an Operation and a set of children. When the expression is evaluated, each child is first evaluated in order, then the resulting values are passed as the arguments to the Operation's evaluate() method.

Constructor & Destructor Documentation

ExpressionTreeNode() [1/7]

PLMD::ExpressionTreeNode::ExpressionTreeNode	(	Operation *	operation,
		const std::vector< ExpressionTreeNode > &	children )

Create a new ExpressionTreeNode.

Parameters

operation	the operation for this node. The ExpressionTreeNode takes over ownership of this object, and deletes it when the node is itself deleted.
children	the children of this node

ExpressionTreeNode() [2/7]

PLMD::ExpressionTreeNode::ExpressionTreeNode	(	Operation *	operation,
		const ExpressionTreeNode &	child1,
		const ExpressionTreeNode &	child2 )

Create a new ExpressionTreeNode with two children.

Parameters

operation	the operation for this node. The ExpressionTreeNode takes over ownership of this object, and deletes it when the node is itself deleted.
child1	the first child of this node
child2	the second child of this node

ExpressionTreeNode() [3/7]

PLMD::ExpressionTreeNode::ExpressionTreeNode	(	Operation *	operation,
		const ExpressionTreeNode &	child )

Create a new ExpressionTreeNode with one child.

Parameters

operation	the operation for this node. The ExpressionTreeNode takes over ownership of this object, and deletes it when the node is itself deleted.
child	the child of this node
