- Method Detail
  - setInput
```
public void setInput(java.io.InputStream is)
```
    Set the current input.
    
    Parameters:
    
    is - the new input.
  - getInput
```
public java.io.InputStream getInput()
```
    Obtain the current input.
    
    Returns:
    
    the current input
  - yyPushInput
```
public void yyPushInput(java.io.InputStream is)
```
    Switch the current input to the new input. The old input and already buffered characters are pushed onto the stack.
    
    Parameters:
    
    is - the new input
  - yyPopInput
```
public void yyPopInput()
```
    Switch the current input to the old input on stack. The currently buffered characters are inserted infront of the old buffered characters.
  - yyInputStackSize
```
public int yyInputStackSize()
```
    Obtain the number of input objects on the stack.
    
    Returns:
    
    the number of input objects on the stack.
  - yyText
```
public java.lang.String yyText()
```
    Get the current token text.
    Avoid calling this function unless it is absolutely necessary since it creates a copy of the token string. The string length can be found by reading _yyLength or calling yyLength () function.
    
    Returns:
    
    the current text token.
  - yyLength
```
public int yyLength()
```
    Get the current text token's length. Actions specified in the CookCC file can directly access the variable _yyLength.
    
    Returns:
    
    the string token length
  - echo
```
public void echo()
```
    Print the current string token to the standard output.
  - yyLess
```
protected void yyLess(int n)
```
    Put all but n characters back to the input stream. Be aware that calling yyLess (0) is allowed, but be sure to change the state some how to avoid an endless loop.
    
    Parameters:
    
    n - The number of characters.
  - begin
```
protected void begin(int baseState)
```
    Set the lexer's current state.
    
    Parameters:
    
    baseState - the base state index
  - yyPushLexerState
```
protected void yyPushLexerState(int newState)
```
    Push the current state onto lexer state onto stack and begin the new state specified by the user.
    
    Parameters:
    
    newState - the new state.
  - yyPopLexerState
```
protected void yyPopLexerState()
```
    Restore the previous lexer state.
  - yyRefreshBuffer
```
protected boolean yyRefreshBuffer()
                           throws java.io.IOException
```
    Throws:
    
    java.io.IOException
  - yyResetBuffer
```
public void yyResetBuffer()
```
    Reset the internal buffer.
  - setBufferSize
```
public void setBufferSize(int bufferSize)
```
    Set the internal buffer size. This action can only be performed when the buffer is empty. Having a large buffer is useful to read a whole file in to increase the performance sometimes.
    
    Parameters:
    
    bufferSize - the new buffer size.
  - yyLex
```
protected int yyLex()
             throws java.io.IOException
```
    Call this function to start the scanning of the input.
    
    Returns:
    
    a token or status value.
    
    Throws:
    
    java.io.IOException - in case of I/O error.
  - yyParse
```
public int yyParse()
            throws java.io.IOException
```
    Call this function to start parsing.
    
    Returns:
    
    0 if everything is okay, or 1 if an error occurred.
    
    Throws:
    
    java.io.IOException - in case of error
  - yyPeekLookahead
```
protected JSONParser.YYParserState yyPeekLookahead()
```
    This function is used by the error handling grammars to check the immediate lookahead token on the stack.
    
    Returns:
    
    the top of lookahead stack.
  - yyPopLookahead
```
protected void yyPopLookahead()
```
    This function is used by the error handling grammars to pop an unwantted token from the lookahead stack.
  - yyClearError
```
protected void yyClearError()
```
    Clear the error flag. If this flag is present and the parser again sees another error transition, it would immediately calls yyParseError, which would by default exit the parser.
    This function is used in error recovery.
  - yyParseError
```
protected boolean yyParseError(int terminal)
                        throws java.io.IOException
```
    This function reports error and return true if critical error occurred, or false if the error has been successfully recovered. IOException is an optional choice of reporting error.
    
    Parameters:
    
    terminal - the terminal that caused the error.
    
    Returns:
    
    true if irrecoverable error occurred. Or simply throw an IOException. false if the parsing can be continued to check for specific error tokens.

```
protected java.lang.Object yyGetValue(int arg)
```
    Gets the object value associated with the symbol at the argument's position.

    the object value associated with symbol.
  - yySetValue
```
protected void yySetValue(java.lang.Object value)
```
    Set the object value for the current non-terminal being reduced.
    
    Parameters:
    
    value - the object value for the current non-terminal.
  - begin
```
protected void begin(java.lang.String state)
```
    This function is used to change the initial state for the lexer.
    
    Parameters:
    
    state - the name of the state
  - yyPushLexerState
```
protected void yyPushLexerState(java.lang.String state)
```
    Push the current state onto lexer state onto stack and begin the new state specified by the user.
    
    Parameters:
    
    state - the new state.
  - yyWrap
```
protected boolean yyWrap()
                  throws java.io.IOException
```
    Check if there are more inputs. This function is called when EOF is encountered.
    
    Returns:
    
    true to indicate no more inputs.
    
    Throws:
    
    java.io.IOException - in case of an IO error
