Calling the accept() function on a Visitable class, i.e. a Node (or subclass thereof) causes the supplied Visitor to traverse the AST.

Parameters

Visitor

$visitor

Implemented in MathParser\Parsing\Nodes\ExpressionNode, MathParser\Parsing\Nodes\FunctionNode, MathParser\Parsing\Nodes\RationalNode, MathParser\Parsing\Nodes\ConstantNode, MathParser\Parsing\Nodes\IntegerNode, MathParser\Parsing\Nodes\SubExpressionNode, MathParser\Parsing\Nodes\NumberNode, MathParser\Parsing\Nodes\PostfixOperatorNode, and MathParser\Parsing\Nodes\VariableNode.
