| 26 | * <p> | |
| 27 | * Checks that a token is followed by whitespace, with the exception that it | |
| 28 | * does not check for whitespace after the semicolon of an empty for iterator. | |
| 29 | * Use Check {@link EmptyForIteratorPadCheck EmptyForIteratorPad} to validate | |
| 30 | * empty for iterators. | |
| 31 | * </p> | |
| 32 | * <p> By default the check will check the following tokens: | |
| 33 | * {@link TokenTypes#COMMA COMMA}, | |
| 34 | * {@link TokenTypes#SEMI SEMI}, | |
| 35 | * {@link TokenTypes#TYPECAST TYPECAST}. | |
| 36 | * </p> | |
| 37 | * <p> | |
| 38 | * An example of how to configure the check is: | |
| 39 | * </p> | |
| 40 | * <pre> | |
| 41 | * <module name="WhitespaceAfter"/> | |
| 42 | * </pre> | |
| 43 | * <p> An example of how to configure the check for whitespace only after | |
| 44 | * {@link TokenTypes#COMMA COMMA} and {@link TokenTypes#SEMI SEMI} tokens is: | |
| 45 | * </p> | |
| 46 | * <pre> | |
| 47 | * <module name="WhitespaceAfter"> | |
| 48 | * <property name="tokens" value="COMMA, SEMI"/> | |
