 /**
 25  
  * <p>Checks the padding of parentheses for typecasts. That is whether a space
 26  
  * is required after a left parenthesis and before a right parenthesis, or such
 27  
  * spaces are forbidden.
 28  
  * <p>
 29  
  * </p>
 30  
  * The policy to verify is specified using the {@link PadOption} class and
 31  
  * defaults to {@link PadOption#NOSPACE}.
 32  
  * </p>
 33  
  * <p>
 34  
  * An example of how to configure the check is:
 35  
  * </p>
 36  
  * <pre>
 37  
  * &lt;module name="TypecastParenPad"/&gt;
 38  
  * </pre>
 39  
  * <p>
 40  
  * An example of how to configure the check to require spaces for the
 41  
  * parentheses of constructor, method, and super constructor invocations is:
 42  
  * </p>
 43  
  * <pre>
 44  
  * &lt;module name="TypecastParenPad"&gt;
 45  
  *     &lt;property name="option" value="space"/&gt;
