Method Detail

acceptInOrder

public abstract void acceptInOrder(AbstractTCLVisitor visitor)

accept a visitor for traversal Inorder

Parameters: visitor

acceptPostOrder

public abstract void acceptPostOrder(AbstractTCLVisitor visitor)

accept a visitor for traversal in Postorder. the right and left subtrees are visited before the root node is visited.

Parameters: visitor

acceptPreOrder

public abstract void acceptPreOrder(AbstractTCLVisitor visitor)

accept a visitor for traversal in Preorder. the root node is visited before the left and the right subtrees are visited.

Parameters: visitor

evaluate

public EvaluationResult evaluate(EvaluationContext context)

Evaluate this Node.

Parameters: context an EvaluationContext value contains all context information necessary for the evaluation

Returns: an EvaluationResult value

Throws: EvaluationException occurs if e.g. an expression contains a reference to a non-existent struct member or if it is tried to add a string and a number
