It seems like you code against a concrete implementation and not the interface Railt\Parser\Ast\NodeInterface as the method getChild() does only exist in the following implementations of said interface: Railt\Compiler\Grammar\Delegate\IncludeDelegate, Railt\Compiler\Grammar\Delegate\RuleDelegate, Railt\Compiler\Grammar\Delegate\TokenDelegate, Railt\Parser\Ast\Rule, Railt\SDL\Frontend\AST\Value\AbstractAstValueNode, Railt\SDL\Frontend\AST\Value\ConstantValueNode, Railt\SDL\Frontend\AST\Value\NullValueNode, Railt\SDL\Frontend\AST\Value\NumberValueNode, Railt\SDL\Frontend\AST\Value\StringValueNode.
