getNodesForAddingRule

public List<Node> getNodesForAddingRule(RuleInput ruleInput)

Specified by:

getNodesForAddingRule in class Node

getCount

public int getCount()

Specified by:

getCount in class Node

getMatchingRule

public Node getMatchingRule(String value)

Description copied from class: Node

This method is specifically added to enable traversal of the rule system trie to find a specific rule. It takes the exact values of rule input fields (value or range) and literally matches them against the keys of the trie. This allows us to locate a specific rule in the trie.

Specified by:

getMatchingRule in class Node

Parameters:

value - value to be matched

Returns:

matching node if one exists, null otherwise
