- Method Detail
  - preventLoops
```
public static Predicate<Matcher> preventLoops()
```
    A predicate for rule tree printing. Prevents SOEs by detecting and suppressing loops in the rule tree.
    
    Returns:
    a predicate
  - lines
```
public static Predicate<Tuple2<Context<?>,Boolean>> lines(int firstLine,
                                          int lastLine)
```
    A predicate usable as a filter (element) of a TracingParseRunner. Enables printing of rule tracing log messages for all input in the given range of input lines.
    
    Parameters:
    firstLine - the number of the first input line to generate tracing message for
    lastLine - the number of the last input line to generate tracing message for
    
    Returns:
    a predicate
  - fromLine
```
public static Predicate<Tuple2<Context<?>,Boolean>> fromLine(int firstLine)
```
    A predicate usable as a filter (element) of a TracingParseRunner. Enables printing of rule tracing log messages for all input in the given range of input lines.
    
    Parameters:
    firstLine - the number of the first input line to generate tracing message for
    
    Returns:
    a predicate
  - untilLine
```
public static Predicate<Tuple2<Context<?>,Boolean>> untilLine(int lastLine)
```
    A predicate usable as a filter (element) of a TracingParseRunner. Enables printing of rule tracing log messages for all input in the given range of input lines.
    
    Parameters:
    lastLine - the number of the last input line to generate tracing message for
    
    Returns:
    a predicate
  - rules
```
public static Predicate<Tuple2<Context<?>,Boolean>> rules(Rule... rules)
```
    A predicate usable as a filter (element) of a TracingParseRunner. Enables printing of rule tracing log messages for all given rules and their sub rules.
    
    Parameters:
    rules - the rules to generate tracing message for
    
    Returns:
    a predicate
  - onlyRules
```
public static Predicate<Tuple2<Context<?>,Boolean>> onlyRules(Rule... rules)
```
    A predicate usable as a filter (element) of a TracingParseRunner. Enables printing of rule tracing log messages for all given rules (without their sub rules).
    
    Parameters:
    rules - the rules to generate tracing message for
    
    Returns:
    a predicate
  - rulesBelow
```
public static Predicate<Tuple2<Context<?>,Boolean>> rulesBelow(Rule... rules)
```
    A predicate usable as a filter (element) of a TracingParseRunner. Enables printing of rule tracing log messages for all sub rules of the given rules.
    
    Parameters:
    rules - the rules whose sub rules to generate tracing message for
    
    Returns:
    a predicate
  - onlyMatches
```
public static Predicate<Tuple2<Context<?>,Boolean>> onlyMatches()
```
    A predicate usable as a filter (element) of a TracingParseRunner. Enables printing of rule tracing log messages for all matched rules.
    
    Returns:
    a predicate
  - onlyMismatches
```
public static Predicate<Tuple2<Context<?>,Boolean>> onlyMismatches()
```
    A predicate usable as a filter (element) of a TracingParseRunner. Enables printing of rule tracing log messages for all mismatched rules.
    
    Returns:
