| 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 | * <module name="TypecastParenPad"/> | |
| 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> | |
