  - operators
```
List<String> operators()
```

    Returns:
    
    A list of operators.
  - getSymbol
```
String getSymbol(String text)
```
    Return the symbol related to an operator text which can be used with this parser.
    
    Parameters:
    
    text - The operator text
    
    Returns:
    
    A symbol.
  - isValid
```
boolean isValid(String text)

    Checks if the supplied text is valid or not.
    
    Parameters:
    
    text - The text to be validated.
    
    Returns:
    
    true if text is valid, else returns false.
  - getErrorMessage
```
String getErrorMessage()
```
    A string with the error message if the parser fails to parse the supplied string.
    
    Returns:
    
    An error message if the parse fails.
  - aggregate
```
default Predicate<T> aggregate(String text)
```
    Aggregates a text i.e. performs aggregation before parsing the text.
