Class TreeNodePattern

java.lang.Object
  org.kahina.core.breakpoint.TreeNodePattern

All Implemented Interfaces:

Serializable

public class TreeNodePattern
extends Object
implements Serializable

TreeNodePatterns are a means of defining which nodes are accepted for use within TreeAutomatonRules as part of the Kahina breakpoint mechanism. Some basic functionality is predefined, allowing the user to exploit Kahina's predefined tree node properties such as For more complex breakpoint patterns based on associated step data, it is possible to use one of the specialized TreeNodePattern classes (such as SourceCodePattern) or to directly inherit from this class and overwrite or overload the decision methods. It is not recommended to use this for child pattern matching, because this breaks the tree automaton logic. For such patterns, use the TreeAutomaton mechanism of node annotations.
