com.puppycrawl.tools.checkstyle.checks.coding.UnnecessarySemicolonAfterOuterTypeDeclarationCheck
- All Implemented Interfaces:
Configurable
,Contextualizable
Checks if unnecessary semicolon is used after type declaration.
This check is not applicable to nested type declarations, UnnecessarySemicolonAfterTypeMemberDeclaration is responsible for it.
-
Property
tokens
- tokens to check Type isjava.lang.String[]
. Validation type istokenSet
. Default value is: CLASS_DEF, INTERFACE_DEF, ENUM_DEF, ANNOTATION_DEF, RECORD_DEF.
To configure the check:
<module name="UnnecessarySemicolonAfterOuterTypeDeclaration"/>
Example:
class A { class Nested { }; // OK, nested type declarations are ignored }; // violation interface B { }; // violation enum C { }; // violation @interface D { }; // violation
To configure the check to detect unnecessary semicolon only after top level class definitions:
<module name="UnnecessarySemicolonAfterOuterTypeDeclaration"> <property name="tokens" value="CLASS_DEF"/> </module>
Example:
class A { }; // violation interface B { }; // OK enum C { }; // OK @interface D { }; // OK
