All Implemented Interfaces:

Configurable, Contextualizable

public final class UnnecessarySemicolonAfterTypeMemberDeclarationCheck
extends AbstractCheck

Checks if unnecessary semicolon is used after type member declaration.

Notes: This check is not applicable to empty statements (unnecessary semicolons inside methods or init blocks), EmptyStatement is responsible for it.

• Property tokens - tokens to check Type is java.lang.String[]. Validation type is tokenSet. Default value is: CLASS_DEF, INTERFACE_DEF, ENUM_DEF, ANNOTATION_DEF, VARIABLE_DEF, ANNOTATION_FIELD_DEF, STATIC_INIT, INSTANCE_INIT, CTOR_DEF, METHOD_DEF, ENUM_CONSTANT_DEF, COMPACT_CTOR_DEF, RECORD_DEF.

Method Details

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:

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.

See Also:

• 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.
