Method Detail

compileNode	back to summary
private void compileNode(Node inputNode, StringBuilder stringBuilder, Stack<Node> cycleCheckStack) throws ScanException

constructRecursionErrorMessage	back to summary
private String constructRecursionErrorMessage(Stack<Node> recursionNodes)

equalNodes	back to summary
private boolean equalNodes(Node node1, Node node2)

handleLiteral	back to summary
private void handleLiteral(Node n, StringBuilder stringBuilder)

handleVariable	back to summary
private void handleVariable(Node n, StringBuilder stringBuilder, Stack<Node> cycleCheckStack) throws ScanException

haveVisitedNodeAlready	back to summary
private boolean haveVisitedNodeAlready(Node node, Stack<Node> cycleDetectionStack) Determine if a node has already been visited already by checking the cycleDetectionStack for its existence. This method is used -- rather than Stack.contains() -- because we want to ignore the Node's 'next' attribute when comparing for equality.
