Class UnnecessarySemicolonAfterOuterTypeDeclarationCheck

  • All Implemented Interfaces:
    Configurable, Contextualizable
    public final class UnnecessarySemicolonAfterOuterTypeDeclarationCheck
extends AbstractCheck

    Checks if unnecessary semicolon is used after type declaration.

    This check is not applicable to nested type declarations, UnnecessarySemicolonAfterTypeMemberDeclaration is responsible for it.

    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

      • getDefaultTokens

        public int[] getDefaultTokens()
        Description copied from class: AbstractCheck
        Returns the default token a check is interested in. Only used if the configuration for a check does not define the tokens.
        Specified by:
        getDefaultTokens in class AbstractCheck
        Returns:
        the default tokens
        See Also:
        TokenTypes

      • getAcceptableTokens

        public int[] getAcceptableTokens()
        Description copied from class: AbstractCheck
        The configurable token set. Used to protect Checks against malicious users who specify an unacceptable token set in the configuration file. The default implementation returns the check's default tokens.
        Specified by:
        getAcceptableTokens in class AbstractCheck
        Returns:
        the token set this check is designed for.

        TokenTypes

      • getRequiredTokens

        public int[] getRequiredTokens()
        Description copied from class: AbstractCheck
        The tokens that this check must be registered for.
        Specified by:
        getRequiredTokens in class AbstractCheck
        Returns:
        the token set this must be registered for.
