public class StringValueParser
extends FieldParser<StringValue>

  - createValue
```
public StringValue createValue()
```
    Description copied from class: FieldParser
    
    Returns an instance of the parsed value type.
    
    Specified by:
    
    createValue in class FieldParser<StringValue>
    
    Returns:
    
    An instance of the parsed value type.
  - getLastResult
```
public StringValue getLastResult()
```
    Description copied from class: FieldParser
    
    Gets the parsed field. This method returns the value parsed by the last successful invocation of FieldParser.parseField(byte[], int, int, byte[], Object). It objects are mutable and reused, it will return the object instance that was passed the parse function.
    
    Specified by:
    
    getLastResult in class FieldParser<StringValue>
    
    Returns:
    
    The latest parsed field.
