public final class UnnecessarySemicolonAfterTypeMemberDeclarationCheck extends AbstractCheck
Checks if unnecessary semicolon is used after type member declaration.
This check is not applicable to empty statements (unnecessary semicolons inside methods or init blocks), EmptyStatement is responsible for it.

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 classAbstractCheck
