Method Detail

addChildNode

public abstract void addChildNode(RuleInput ruleInput,
                                  Node childNode)

removeChildNode

public abstract void removeChildNode(RuleInput ruleInput)

getNodes

public abstract List<Node> getNodes(String value,
                                    boolean getAnyValue)
                             throws Exception

Throws:

Exception

getNodesForAddingRule

public abstract List<Node> getNodesForAddingRule(RuleInput ruleInput)
                                          throws Exception

Throws:

Exception

getCount

public abstract int getCount()

getMatchingRule

public abstract Node getMatchingRule(String value)

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.

Parameters:

value - value to be matched

Returns:

matching node if one exists, null otherwise

getRule

public Rule getRule()

setRule

public void setRule(Rule rule)

getName

public String getName()
