```
    Set the PrintStream on which the debug output is printed.
    
    Parameters:
    s - The stream that is used for debugging output.
  - getDebugLevel
```
public final int getDebugLevel()
```
    Answer the verbosity of the debugging output; 0 means that all kinds of output from the parser are suppressed.

    getDebugLevel in class Dapparse
  - setDebugLevel
```
public final void setDebugLevel(int level)
```
    Set the verbosity of the debugging output; 0 means that all kinds of output from the parser are suppressed.
    
    Specified by:
    
    setDebugLevel in class Dapparse
    
    Parameters:
    level - The verbosity level for debugging output.
  - yyerror
```

```
protected final void yycdebug(String s)
```
  - recovering
```
public final boolean recovering()
```
    Return whether error recovery is being done. In this state, the parser reads token until it reaches a known state, and then restarts normal operation.
  - parse
```
public boolean parse()
              throws ParseException,
                     ParseException
```
    Parse input from the scanner that was specified at object construction time. Return whether the end of the input was reached successfully.
    
    Returns:
    true if the parsing succeeds. Note that this does not imply that there were no syntax errors.
    
    Throws:
    
    ParseException
  - parse
```
public boolean parse(String input)
              throws ParseException
