        Parameters:
        sourceCodeFile - The File.
      • getSourceCodeFilename

        public String getSourceCodeFilename()
        Get the file name associated with the current source file. If there is no source file, then an empty string is returned.
        Returns:
        The file name.
      • setSourceCodeFilename

        @Deprecated
        public void setSourceCodeFilename​(String filename)
        Deprecated.
        This method will be removed. The file should only be set with setSourceCodeFile(File). Setting the filename here has no effect.
        Set the file name associated with the current source file.

        filename - The file name.
      • getLanguageVersion

        public LanguageVersion getLanguageVersion()

      • setLanguageVersion

        public void setLanguageVersion​(LanguageVersion languageVersion)
        Set the LanguageVersion associated with the current source file. This may be set to null to indicate the version is unknown and should be automatically determined.

      • setIgnoreExceptions

        public void setIgnoreExceptions​(boolean ignoreExceptions)
        Configure whether exceptions during applying a rule should be ignored or not. If set to true then such exceptions are logged as warnings and the processing is continued with the next rule - the failing rule is simply skipped. This is the default behavior.
        If set to false then the processing will be aborted with the exception. This is especially useful during unit tests, in order to not oversee any exceptions.
        Parameters:
        ignoreExceptions - if true simply skip failing rules (default).
      • isIgnoreExceptions

        public boolean isIgnoreExceptions()
        Gets the configuration whether to skip failing rules (true) or whether to throw a a RuntimeException and abort the processing for the first failing rule.
        Returns:
        true when failing rules are skipped, false otherwise.
